hamartoma vs teratoma

The comparison of these three cases should serve to emphasize the diversity of multilineage tumors (hamartomas and GCT) of the upper respiratory tract in regards to their biology, age of presentation and clinical outcomes. Cowden syndrome is a serious genetic disorder[13] characterized by multiple hamartomas.

Many other hamartomatous and teratoid lesions may arise in sinonasal region including mesenchymal, adenomatoid, and glandular hamartomas depending on the predominance of the specific structures [2]. Immunohistochemical analysis revealed diffuse expressions of cytokeratins (AE1/3 and CK5/6) in the branching ductal epithelium and focal expression among myoepithelial cells. http://www.biomedcentral.com/1472-6815/8/8/prepub, http://creativecommons.org/licenses/by/2.0. Hamartomas result from an abnormal formation of normal tissue, although the underlying reasons for the abnormality are not fully understood. On cut section the tumor was composed of different mature tissue structures including skin, hair, cartilage and centrally located bone. Prognosis will depend upon the location and size of the lesion, as well as the overall health of the patient. 1998, 32: 84-10.1046/j.1365-2559.1998.0241a.x. We describe here two new cases of multilineage tumors including sinonasal teratocarcinosarcoma [SNTCS], and congenital oronasopharyngeal teratoma (epignathus) and compare their features with those of a new case of a rare salivary gland anlage tumor [SGAT], an entity for which the pathogenesis is unclear (i.e. Hum Pathol. Send thanks to the doctor. 10.1046/j.1440-1827.2000.01012.x. In pathology|lang=en terms the difference between hamartoma and teratoma. On dissection, the tumor was found to arise from the hard palate and completely filled the oral cavity and upper aero/digestive tract with dilatation of the pharynx (Figure 3A). Rarely solid with mature tissues Benign. Salem F, Rosenblum MK, Jhanwar SC, Kancherla P, Ghossein RA, Carlson DL: Teratocarcinosarcoma of the nasal cavity and paranasal sinuses: report of three cases with assessment for chromosome 12p status. A 30-year-old G2P1 woman presented at 29 weeks gestation with signs of polyhydramnios. Because a hamartoma typically lacks elastic tissue, it may lead to the formation of aneurysms and thus possible hemorrhage. A hypothalamic hamartoma (HH) is a rare, benign (noncancerous) brain tumor or lesion of the hypothalamus. 10.1016/j.humpath.2007.09.002. On physical exam a large polypoid lesion filled the right naris and MRI identified an extensive right nasal passage mass eroding through the cribriform plate of the right ethmoid sinus into the cranial cavity (Figure 1). A clinicopathologic study of 20 cases. It usually occurs when an abnormal amount of normal cells collect on healthy tissue. Tera Term for Windows 32-bit/64-bit (latest version 2021). Malignant tumors of germ cell origins are more likely to affect adults with insidious symptom development, while benign tumors can nevertheless cause dramatic clinical symptoms which, under certain circumstances, can be fatal. Google Scholar. Hamartomas can look similar to cancer on imaging studies, and for this reason, can be very frightening. These aberrations are detectable by conventional cytogenetics when fresh tissue is available for cultures. … 10.1007/s00383-003-1048-8. Arch Otolaryngol Head Neck Surg. 10.1038/nrc1568. 10.1016/j.joms.2003.05.012. Ovarian teratomas are the most common group of ovarian germ cell tumors. Briefly, 200 ng of each rhodamine-5-dUTP labeled BAC clone was precipitated together with 5 times Human Cot-1 DNA (Invitrogen, Carlsbad, CA, USA) and a spectrum green alpha-satellite probe for the centromeric region of chromosome 12. Barrow Neurological Institute 268 views. The most important factors that determine the outcome include: size of the tumor, degree of facial distortion, airway obstruction, difficulties in management and uni/bidirectional growth pattern of the tumor [18]. Fetal Diagn Ther. However, when immature elements predominate, extraskeletal Ewing sarcoma, small cell carcinoma, lymphoma, and rhabdomyosarcoma enter the differential diagnosis. SNTCS lacks features of embryonal carcinoma, choriocarcinoma, and seminoma [3]. Additionally fluorescent in-situ hybridization (FISH) can be used to detect these abnormalities in formalin fixed paraffin embedded tissues. Sinonasal teratocarcinosarcoma (SNTCS), also previously described as teratoid carcinosarcoma, malignant teratoma, blastoma, and teratocarcinosarcoma is among the rarest with one study revealing only 1 case (0.5%) of SNTCS among 200 malignant sinonasal tumors [2]. Immunohistochemically, the epithelial components were positive for keratins and EMA, and showed focal positivity for AFP. 10.1055/s-2006-942271. Martínez Redondo R, Rey López A, Reguerra Parra V, Bolaòos Rodríguez C: Sinusal teratocarcinosarcoma. Br J Oral Maxillofac Surg. A hamartoma resembles a neoplasm, but in most cases, it does not show any tendency to evolve into one. SGAT exhibits benign behavior and no recurrences after complete surgical resection were reported in the literature [26]. 2006, 10: 339-342. Due to its histologic features this lesion can be easily misdiagnosed as a neoplasm of a germ cell origin. It comes from a pluri ... Read More. It is a part of any tissue that either grows faster or without the usual organization of its neighbor cells. Surgical resection is the treatment of choice when the cyst grows in size and if a solid component is present. ZG participated in diagnostics, conceived the study design, wrote and approved the final manuscript. By strict definition, a mature teratoma contains all three germinal layers. hamartoma A tumor-like, non-neoplastic disordered proliferation of mature tissues that are native to a site of origin–eg, exostoses, nevi and soft tissue hamartomas; although most hamartomas are benign, some histologic subtypes–eg, neuromuscular hamartoma, may proliferate aggressively. Albrecht in 1904. Dr. Devon Webster answered. Google Scholar. Cite this article. 1999, 115: 1-10. Not surprisingly, therefore, the pathologic evaluation and clinical management of these tumors can be very difficult. Smooth muscle bundles (arrows) and fibrous tissue. The head and neck region including the upper respiratory tract is a very rare location for such tumors in both children and adults, which can cause diagnostic and therapeutic difficulties. The tumor measured 5.5 × 4 × 2.5 cm and weighed 36 g. It was completely covered by skin including an area of showing hairy growth. However, cases of neoplastic evolution have occurred with these lesions. Neural markers (S100, GFAP, synaptophysin, chromogranin, NSE) were focally positive in all elements, as were CD99 and desmin. Teratomas are histologically classified as either mature or immature, where immature elements consist mainly of primitive neuroglial tissue and neuroepithelial rosettes. They are rare congenital tumors constituting less than 2% of all congenital teratomas, and with an incidence estimated at from 1:35.000 to 1:200.000 live births [12]. 10.1542/peds.112.1.e66. AFIP images. Two centre report. 2 thanks. [5][6] The two can be differentiated as follows: a hamartoma is an excess of normal tissue in a normal situation (e.g., a birthmark on the skin), while a choristoma is an excess of tissue in an abnormal situation (e.g., pancreatic tissue in the duodenum). SGAT is quite rare tumor with only 24 cases (including the case presented in this paper) described since Dehner et al [20] introduced this entity. A tumor was visible through the slightly opened mouth appearing as a tongue-like structure with a blunt border and skin-like surface. Epub 2007 Mar 26. Pathol Res Pract. They did not consider hamartoma as a solitary lesion and, apart from Carney's triad, tried to define a "pulmonary hamartoma syndrome." Teratoma typically form in the ovary, testicle, or coccyx.. Mature ovarian teratomas are slow-growing (1-2 mm a year) and, therefore, some advocate nonsurgical management. In our cases we were able to perform cytogenetic analysis on SNCTS and identify trisomy of 12 with a subpopulation of cells showing additional deletion of 1p chromosome. Conventional cytogenetic analysis of 20 metaphase cells identified a hyperdiploid clone characterized by trisomy 12, with an additional subclone characterized by a del(1 p). https://doi.org/10.1186/1472-6815-8-8, DOI: https://doi.org/10.1186/1472-6815-8-8. Part of The search utilized the pathology files of Yale-New Haven Hospital using CoPath laboratory information system. In our case this one feature prevented successful intubation after birth and caused death from what might otherwise have been considered a benign neoplasm. Labor was induced with successful delivery, but postnatal intubation was unsuccessful and the infant died shortly after delivery. Additionally, the definition of hamartoma versus benign neoplasm is often unclear, since both lesions can be clonal. 10.1080/14767050600647621. With ductal hyperplasia resembling gynecomastia. 10.1002/1097-0142(19840515)53:10<2140::AID-CNCR2820531025>3.0.CO;2-Y. As teratomas are germ cell tumours they can host a variety of non-tumour native tissues. No transphenoidal intracranial extension of the tumor was found. Both teratoma and seminoma are germ cell tumors, which share some of the similar characteristics, but they do differ in many ways. SNTCS is highly aggressive and occurs mainly located in the nose and paranasal sinuses although tumors occurring in other locations including the nasopharynx and oral cavity have been described [3, 8, 11] though recently published review of 10 cases with long follow up (up to 372 months) from a single institution revealed significantly better outcome in patients with SNTCS than previously reported [7].

A hamartoma is a mostly benign,[2] local malformation of cells that resembles a neoplasm of local tissue but is usually due to an overgrowth of multiple aberrant cells, with a basis in a systemic genetic condition, rather than a growth descended from a single mutated cell (monoclonality), as would typically define a benign neoplasm/tumor. Cardesa A, Alos L, Franchi A: Nasal cavity and paranasal sinuses. The symptoms typically begin in early infancy and are progressive, often into general cognitive and/or functional disability. Get help now: 2008, 46: 317-319. Teratomas are most common in … Vranic, S., Caughron, S.K., Djuricic, S. et al. Trisomy 12, as a primary or secondary event, is a well known cytogenetic abnormality occurring in majority of malignant germ cell tumors [1, 27]. Hamartomas of the spleen are uncommon but can be dangerous. Neoplasm.   They are made up of abnormal but not cancerous cells similar to the cells that make up the tissue where they originate. Our case is the first described with delayed presentation (12 months) and the oldest previously described patient presented with the tumor at the age of three months [22]. Hamartomas, teratomas and teratocarcinosarcomas of the head and neck: Report of 3 new cases with clinico-pathologic correlation, cytogenetic analysis, and review of the literature. It is different from choristoma, a closely related form of heterotopia. (d) After excision of the mass, the pelvic floor muscles are closed vertically in the midline from below upwards. Imaging studies of the chest did not identify a cause. Karyotype of the tumor was described as: 47, XX, +12[18]/47, idem, del(1)(p31.1p36.3)[2] (see Figure 2, Table 1). View 1 more answer. Cowden syndrome is considered a PTEN hamartoma tumor syndrome (PHTS), which also includes Bannayan–Riley–Ruvalcaba syndrome, Proteus syndrome and Proteus-like syndrome. Pediatr Surg Int. 2007, 36: 534-538. No cartilaginous or other heterologous elements were found. Fluorescent in-situ hybridization (FISH) with LSI DNA probes for 1p36 and 1q25 was normal and did not identify chromosomal gains or losses in either. Fetal sonography presentation and perinatal risks of sacrococcygeal teratoma and terminal myelocystocele are compared, and we emphasize the importance of obtaining fetal MR imaging to establish an accurate diagnosis. Malagón HD, Valdez AM, Moran CA, Suster S: Germ cell tumors with sarcomatous components: A clinicopathologic and immunohistochemical study of 46 cases. Background Oropharyngeal teratoma may occur by itself or together with other craniofacial malformations, most commonly cleft palate. In addition, neoplasms can be associated with hamartomas without directly … A hamartoma is a benign, focal malformation that resembles a neoplasm in the tissue of its origin. 0 comment. (B-D): Histopathologically, the tumor was composed of different mature teratomatous tissue including brain (B), bone with moderately cellular bone marrow (C), epidermis with numerous hairy follicles and sebaceous glands (D). 1994, 18: 25-36. Crazzolara R, Puelacher W, Ninkovic M, Zelger B, Buchberger W, Meister B, Zimmerhackl LB, Klein-Franke A: Teratocarcinosarcoma of the oral cavity. Most are asymptomatic, but they can cause dyspepsia or upper gastrointestinal bleeding. hamartoma versus neoplasm). Teratomas represent true neoplasms rather than hamartomatous malformations. We also want to point out that our case of SNTCS bore an additional finding in a form of the deletion of 1p chromosome in a subclone of SNTCS. They are particularly likely to cause major health issues when located in the hypothalamus, kidneys, lips, or spleen. Prior to hybridization the slides were pretreated using the VP 2000 automated slide processor (Vysis/Abbott, Inc.) following a modified version of the manufacturer's recommended protocol. We correlate their presenting clinico-pathological features and compare histologic and cytogenetic features in an attempt to elucidate their pathogenesis and biologic potentials. The cancerous presence depends on the location of the teratoma in your body. 10.1016/j.ijporl.2004.08.014. Mature teratoma - Benign cystic. Learn new and interesting things. A teratoma is a rare type of tumor that can contain fully developed tissues and organs, including hair, teeth, muscle, and bone. Google Scholar.

Toggle navigation. 10.1002/(SICI)1098-2264(199906)25:2<134::AID-GCC9>3.0.CO;2-Y. Hamartomas are by definition benign, slow-growing or self-limiting,[2][3] though the underlying condition may still predispose the individual towards malignancies. Other associated problems with these lesions include developmental delay, behavioral problems and endocrinological disorders. Terms and Conditions, These are the first reported cytogenetic abnormalities found in SNTC. Petechiae were present on the anterior chest and neck region. Share to Twitter Share to Facebook Share to Pinterest. - Duration: 0:56. Lesions such as adenomas, developmental cysts, hemangiomas, lymphangiomas and rhabdomyomas within the kidneys, lungs or pancreas are interpreted by some experts as hamartomas while others consider them true neoplasms.

Ovarian teratoma: Also called a dermoid cyst of the ovary, this is a bizarre tumor, usually benign, in the ovary that typically contains a diversity of tissues including hair, teeth, bone, thyroid, etc. Lester D.R. The line between benign tumour and hamartoma is thin, if one considers that a hamartoma can be clonal and some benign tumours have a slow growth rate. They are congenital (meaning they are present at the time of birth) but ... Read More. Prenat Diagn. Diagnosis of tailgut is sometimes challenging. We describe here two new cases of multilineage tumors including sinonasal teratocarcinosarcoma [SNTCS], and congenital oronasopharyngeal teratoma (epignathus) and compare their features with those of a new case of a rare salivary gland anlage tumor [SGAT], an entity for which the pathogenesis is unclear (i.e. Shaffer LG, Tommerup N: ISCN 2005. The comparison of these three cases should serve to emphasize the diversity of multilineage tumors (hamartomas and GCT) of the upper respiratory tract in regards to their biology, age of presentation and clinical outcomes. is that hamartoma is (pathology) a benign mass of disorganized tissue while teratoma is (pathology) a benign or malignant tumour, especially of the gonads, that arises from germ cells and consists of different types of tissue such as skin, hair, or muscle. PubMed  In this article, I'll only try to mention the main tricky differences between them. Examples are chondrosarcomas arising in osteochondromas and neurofibrosarcomas arising in patients with von Recklinghausen disease. Teratoma: A tumor comprising of one or more of the three germinal layers and is composed of different kinds of tissue, none of which normally occur together or at the site of the tumor. Complications may include ovarian torsion, testicular torsion, or hydrops fetalis.

CAS  0. The terms hamartoma, choristoma, embryoma, teratoma and dermoid refer to separate and distinct tumors in the head and neck. Both structures expressed smooth muscle actin (SMA) and vimentin (Figure 4C). The cells that comprise the hamartoma maintain their function, unlike cells that create malignant tumors.They have limited growth potential, thus they are not considered tumors by the medical community. Dermoid cyst: usually mature teratoma which resembles skin; some use these terms interchangeably Gliomatosis peritonei: peritoneal implants exclusively composed of mature glial tissue; benign if all tissue is mature and other teratomatous elements are absent Case reports. 10.1148/rg.251045156.

Herrmann BW, Dehner LP, Lieu JEC: Congenital salivary gland anlage tumor: a case series and review of the literature. There is a strong association between cardiac rhabdomyomas and tuberous sclerosis (characterized by hamartomas of the central nervous system, kidneys, and skin, as well as pancreatic cysts); 25-50% of patients with cardiac rhabdomyomas will have tuberous sclerosis, and up to 100% of patients with tuberous sclerosis will have cardiac masses by echocardiography. It primarily affects adults (average age 60 years) with only 87 cases reported in the available literature [3–7]. 2005, Basel: Karger. Symptoms are usually from congestive heart failure; in utero heart failure may occur. One of the most troublesome hamartomas occurs on the hypothalamus.

Imaging is an important component of the initial workup. Klin Pädiatr. Genes Chromosomes Cancer. Acta Otorrinolaringol Esp. A study of Bussey et al [23] concluded that the gonadal and extragonadal teratomas, both mature and immature of children four years and younger, mainly carried normal karyotype without cytogenetic abnormalities though several papers reported diverse cytogenetic abnormalities even in congenital mature teratomas including epignathi [30, 31]. There was no pulmonary hypoplasia. It typically occurs in neonates in the midline of the nasopharynx with a potential to cause life-threatening airway-obstruction [20]. Deveci SM, Deveci G: Blastomatous tumor with teratoid features of nasal cavity: Report of a case and review of the literature. … Information about the SNOMED CT code 189847002 representing Malignant teratoma.

Cookies policy. A teratoma is a tumor that is made up of many different types of tissue. Herein, we describe for the first time a case of SNTCS with trisomy 12 with a subclone characterized by an additional deletion of 1 p. We further describe and contrast the case with an epignathus and SGAT that showed no cytogenetic aberrations. Hepatic MCN vs cystic hamartoma - how can we differentiate? This characteristic distinguishes SNTCS from other malignant germ cell tumors. They are the most common tumor of the heart in children and infants. By using this website, you agree to our (Nebraska Medical Center, Omaha, NE) for their excellent cytogenetics support. Larger lesions are often surgically removed. The authors declare that they have no competing interests. (A): Gross appearance of the epignathus with tongue-like structures with the blunt border and skin-like surface. Malignant sinonasal tumors are very rare and represent less than 1% of all cancers and approximately 3% of malignancies of the head and neck region [2]. CAS  Ovarian teratoma: Also called a dermoid cyst of the ovary, this is a bizarre tumor, usually benign, in the ovary that typically contains a diversity of tissues including hair, teeth, bone, thyroid, etc. This result combined with its histopathological and clinical features of SGAT support the thesis that SGAT might be a hamartomatous, developmental disorder rather than true neoplastic lesion. Notably, loss of 1p (like a gain of chromosome 12p) has also been detected in many other malignant tumor types (e.g. Ovarian teratomas are the most common group of ovarian germ cell tumors. 10.1159/000066379. In: Pediatric Tricky Topics, Volume 2. Loss of 1p is a well characterized genetic feature of embryonal tumors, particularly pediatric germ cell tumors as well as among malignant GCT where it is associated with aggressive clinical course and a poor prognosis [23, 28, 29]. Hamartoma vs Choristoma - What's the difference? Some lung hamartomas can compress surrounding lung tissue to a degree, but this is generally not debilitating and is often asymptomatic, especially for the more common peripheral growths. Possible differential diagnoses in this location include teratoma, dermoid cyst, anterior sacral meningocele, and presacral abscess. A teratoma is a type of germ cell tumor which contains several different types of cells, caused when germ cells run amok and start replicating where they shouldn't.
