hamartoma vs teratoma

Posted on January 17, 2021

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]. Shaffer LG, Tommerup N: ISCN 2005. 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. 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. A teratoma is a tumor that is made up of many different types of tissue. Although uncommon in the general population, they account for the largest proportion of fetal intracranial neoplasms (26-50% of fetal brain tumors 3,6). Areas with necrosis and cystic degeneration might also be present [22]. PubMed  10.1001/archotol.134.6.592. Subcutaneous fibro-fatty tissue contained skeletal muscle fascicles and salivary glands. Semir Vranic. 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. They are congenital (meaning they are present at the time of birth) but ... Read More. The most of epignathi are attached to the base of the skull (hard palate) or to the mandible and are rarely associated with other congenital anomalies [11, 13–17]. Co-denaturation of the DNA probes and patient slide was performed on a HYBrite™ instrument (Vysis/Abbott, Inc.) at 80° C for 5 minutes, followed by an overnight hybridization at 37°C, post-wash in 2 × SSC/0.1% NP-40 at 73° C and 2 × SSC at room temperature for 2 minutes each, and counter-stain with DAPI II. The pre-publication history for this paper can be accessed here:http://www.biomedcentral.com/1472-6815/8/8/prepub. Hamartomas of the spleen are uncommon but can be dangerous. Hybridization signals were assessed in 100 interphase nuclei and images were acquired using the Cytovision Image Analysis System (Applied Imaging, Santa Clara, CA). Teratomas are most common in … 2006, 218: 296-302. Teratomas are histologically classified as either mature or immature, where immature elements consist mainly of primitive neuroglial tissue and neuroepithelial rosettes. It is a part of any tissue that either grows faster or without the usual organization of its neighbor cells. Petechiae were present on the anterior chest and neck region. [14] They may obstruct practically any organ in the body, such as the colon, eye, etc. Epub 2007 Mar 26. Complications may include ovarian torsion, testicular torsion, or hydrops fetalis. It comes from a pluri ... Read More. Int J Pediatr Otorhinolaryngol. 2008, 134: 592-5. Both cytogenetic abnormalities are characteristically present in malignant germ cell tumors providing for the first time evidence that this rare tumor type indeed might represent a variant of a germ cell neoplasm. 2008, 46: 317-319. If it occurs in a newborn, it is usually benign (harmless) and can be removed surgically. 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. Histologic examination of the tumor showed variable mature tissue types including bone with bone marrow, hyaline cartilage, epidermis and thick dermis with hairy follicles and sebaceous glands (Figure 3B–D). 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. A hamartoma is a benign tumor that may occur in the lungs, heart, skin, brain, breast, or other regions. A hamartoma is a noncancerous tumor made of an abnormal mixture of normal tissues and cells from the area in which it grows.. Hamartomas can … [9] They almost always arise from connective tissue and are generally formed of cartilage, connective tissue, and fat cells, although they may include many other types of cells. 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]. The outcome and survival of newborns with epignathus are generally unfavorable. Tera Term is a free and open source terminal emulator software download filed under ssh/telnet clients and made available by TeraTerm Project for Windows.. Thus, SGAT is one of the rarest causes of neonatal nasal airway obstruction, and is rarer than congenital tumors like epignathus whose incidence is estimated to be 1:35.000 to 1:200.000 live births [12]. This type of tumor is actually present at birth, but it may not be noticed until later in life, and it could be considered a form of congenital birth defect. [3] Many of these conditions are classified as overgrowth syndromes or cancer syndromes. Hamartoma refers to a disorganized collection of normal mature tissues for the anatomic area.Heterotopias are normal tissue in an abnormal location (misplaced or displaced). 1993, 91: 223-228. Kosmaidou-Aravidou Z, Siabalioti G, Karpathios S, Grigori P, Panani A: Prenatal diagnosis of a cervical teratoma with a cytogenetic study. Cardiac rhabdomyomas are hamartomas composed of altered cardiac myocytes that contain large vacuoles and glycogen. However, the majority of these tumors are outside the heart or involve the pericardium only. Angiomyolipoma of the kidney was previously considered to be a hamartoma or choristoma. The clinical impression was of hypertrophied adenoids, but on closer examination, a mass at the midline posterior nasopharynx was discovered. Zahn S, Sievers S, Alemazkour K, Orb S, Harms D, Schulz WA, Calaminus G, Göbel U, Schneider DT: Imbalances of chromosome arm 1p in pediatric and adult germ cell tumors are caused by true allelic loss: a combined comparative genomic hybridization and microsatellite analysis. Examples are chondrosarcomas arising in osteochondromas and neurofibrosarcomas arising in patients with von Recklinghausen disease. Cite this chapter as: Houser C.M. Histological composition of the tumor fully corresponded to a solid mature teratoma (oronasopharyngeal teratoma/epignathus). PubMed  According to a news published inSeptember 2019, in Greater Noida, a baby boy was born with a teratoma on his coccyx (tailbone) that looked similar to a one and half inch tail. Atypical immature epithelial, mesenchymal and primitive neuroectodermal components were recognized at high magnification (Figure 2). In: Pediatric Tricky Topics, Volume 2. 10.1038/nrc1568. (2016) Selected Hematology and Oncology Topics: Hamartomas vs. Teratomas. 10.1016/j.cancergencyto.2006.11.013. Nature Rev Cancer. One general danger of hamartomas is that they may impinge into blood vessels, resulting in a risk of serious bleeding. No comments: Post a Comment. Hematoxylin and eosin (H&E) stain as well as automated immunohistochemistry (IHC) were used to characterize and diagnose these tumors. Imaging is an important component of the initial workup. Dermoid Cyst: mamillae or ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 1dbf32-ZDc1Z At CT and MR imaging, immature teratomas characteristically have a large, irregular solid component containing coarse calcifications. 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. Symptoms depend on the size of the tumor, its location relative to the conduction system, and whether or not it obstructs blood flow. Toggle navigation. Small foci of fat help identify these tumors. … 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]. Sort by: GROWING TERATOMA SYNDROME - A RARE COMPLICATION OF IMMATURE TERATOMA OF … 10.1017/S0022215100098546. There was no growth retardation. Because their growth is limited, hamartomas are not true tumours and some, such as hemangiomas that occur as birthmarks, may disappear with time. Teratomas: Teratomas are a type of tumor or mass made up of different types of tissues. … Carrizo F, Pineda-Daboin K, Neto AG, Luna MA: Pharyngeal teratocarcinosarcoma: review of the literature and report of two cases. 2008, 39: 605-609. 0. Because of their rarity, cytogenetic and molecular studies of these upper respiratory tract tumors showing multilineage histologic features have generally not been done. 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. BMC Ear Nose Throat Disord 8, 8 (2008). SD and NB carried out autopsy, wrote and approved the final manuscript. Pathol Int. The mesenchymal and neuroectodermal components were positive for vimentin. A hamartoma (from Greek hamartion “bodily defect”) is a benign (noncancerous) tumorlike malformation made up of an abnormal mixture of cells and tissues found in … Germ-cell tumors are a heterogeneous group of neoplasms that primarily occur in the gonads (both ovaries and testes) but can also occur at extragonadal sites along the midline of the body. Int J Pediatr Otorhinolaryngol. Newly developed procedures including ex-utero intra partum (EXIT) procedure may enable survival of newborns with epignathus. While malignant tumours contain poorly differentiated cells, hamartomas consist of distinct cell types retaining normal functions. Hamartoma vs Choristoma - What's the difference? Many are downloadable. Surg Pathol. A retrospective database search was conducted and coded as “tailgut cyst or retrorectal cystic hamartoma” to identify cases of possible TGC between January 2005 and January 2019. Post mortem examination revealed a female fetus with growth parameters in keeping with 28 weeks of gestation. 2003, 112: e66-e69. Parrington JM, West LF, Heyderman E: Chromosome analysis of parallel short-term cultures from four testicular germ-cell tumors. The following primary antibodies were used in IHC: cytokeratin AE1/3, HMB-45, epithelial membrane antigen (EMA), S100, chromogranin, CD99 (DakoCytomation, Carpinteria, CA); cytokeratin 5/6, smooth muscle actin (SMA), alpha-feto protein (AFP), glial fibrillary acidic protein (GFAP), synaptophysin, neuron specific enolase (NSE), myoglobin, myogenin, and p53 (Cell Marque, Hot Spring, AR); vimentin, desmin, bcl-2 (Ventana Medical Systems, Tucson, AZ). 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. A 30-year-old G2P1 woman presented at 29 weeks gestation with signs of polyhydramnios. Neoplasm, Hamartoma, Teratoma, Hyperplasia Pathology > Cell growth disturbances All of those conditions are types of different cell growth disturbances. Most are asymptomatic, but they can cause dyspepsia or upper gastrointestinal bleeding. In contrast to malignant germ cell tumors, benign teratomas of the oronasopharyngeal region (so called epignathus) are composed of mature, highly organized structures. For unknown reasons, SGAT is much more prevalent among males and this was supported in our case. All Time Show: Recommended. Diagnosis of tailgut is sometimes challenging. About 50% of such cases manifest abdominal pain, and they are often associated with hematologic abnormalities and spontaneous rupture. 10.1002/1097-0142(19840515)53:10<2140::AID-CNCR2820531025>3.0.CO;2-Y. It primarily affects adults (average age 60 years) with only 87 cases reported in the available literature [3–7]. Terms and Conditions, hamartoma versus neoplasm). 0 comment. An X-ray will often not provide a definitive diagnosis, and even a CT scan may be insufficient if the hamartoma lacks the typical cartilage and fat cells. 10.1016/S0165-5876(01)00575-4. They are particularly likely to cause major health issues when located in the hypothalamus, kidneys, lips, or spleen. The presentation of each lesion reflected in part the age of the patient, severity of disease and the biological potential of the tumor. 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). http://www.biomedcentral.com/1472-6815/8/8/prepub, http://creativecommons.org/licenses/by/2.0. Dr. Aarti Sekhar at May 14, 2020. Zhonghua Bing Li Xue Za Zhi. Hyaline cartilage and adipose tissue . 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]. An 85 year old African American female presented to her primary care physician with complaint of spitting up blood. They grow along with, and at the same rate as, the organ from whose tissue they are made, and, unlike cancerous tumors, only rarely invade or compress surrounding structures significantly. 10.1002/gcc.20363. 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. SUMMARY: This case exemplifies the difficulty in differentiating cystic sacrococcygeal teratoma and terminal myelocystocele. Germ-cell tumors (GCT) are a histologically and biologically diverse group of neoplasms which primarily occur in the gonads but also develop at different extragonadal sites in the midline of the body. 2000, 50: 71-75. Well defined fibrous tumor, ducts separated by connective tissue. They can be worrisome, especially if situated deep in the lung, as it is sometimes difficult to make the important distinction between a hamartoma and a lung malignancy. By using this website, you agree to our Myoid hamartoma: also has smooth muscle stroma; may contain epithelioid cells (Arch Pathol Lab Med 1996;120:676, Hum Pathol 1985;16:212) Microscopic (histologic) images. Shah A, Gordon AR, Ginsberg GG, Furth EE, Levine MS. Case report: ectopic pancreatic rest in the proximal stomach mimicking gastric neoplasms. 2 thanks. Because of its heterogeneous composition, the diagnosis of SNTCS can be quite challenging, particularly if the sampling is not sufficient. ZG participated in diagnostics, conceived the study design, wrote and approved the final manuscript. Background Oropharyngeal teratoma may occur by itself or together with other craniofacial malformations, most commonly cleft palate. No abstract available. These ducts were lined by cuboidal or low columnar epithelium that frequently was transformed into squamous-type lining. Information about the SNOMED CT code 255106001 representing Teratoma of testis. 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. Cohen EG, Yoder M, Thomas RM, Salerno D, Isaacson G: Congenital salivary gland anlage tumor of the nasopharynx. Genes Chromosomes Cancer. Despite this, many hamartomas are found to have clonal chromosomal aberrationsthat are acquired through somatic mutations, and on this basis the term hamartoma is som… (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). teratoma/dermoid cyst) and choristoma is thin. 1995, 191: 166-171. (b) The patient placed in the prone (face down) position. 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]. The hypothalamus is located at the base of the brain and regulates many of the “automatic” functions of the brain, including hunger, thirst, temperature, passion, and hormone regulation. Lung hamartomas may have popcorn-like calcifications on chest xray or computed tomography (CT scan). A hamartoma is a benign, focal malformation that resembles a neoplasm in the tissue of its origin. Br J Oral Maxillofac Surg. Immunohistochemical analysis revealed diffuse expressions of cytokeratins (AE1/3 and CK5/6) in the branching ductal epithelium and focal expression among myoepithelial cells. MRI revealed a large polypoid tumor mass eroding through the cribriform plate of the right ethmoid sinus into the cranial cavity. In addition, neoplasms can be associated with hamartomas without directly … Article  The histologically mature (benign) congenital oronasopharyngeal teratoma (epignathus) caused death from upper airway obstruction in a neonate. Teratoma is a well-encapsulated tumor having components derived from all three germ layers, but seminoma arises from the germ cell epithelium of the seminiferous tubules. They are treated, if at all, by surgical resection, with an excellent prognosis: generally, the only real danger is the inherent possibility of surgical complications. Additional growths can form in many parts of the body, especially in bones, CNS, the eyes, the genitourinary tract, the GI tract, and mucosa. Hamartomas occur in many different parts of the body and are most often asymptomatic incidentalomas (undetected until they are found incidentally on an imaging study obtained for another reason). Despite their low frequency, a variety of histological types can be found. (D): FISH analysis revealed 2 copies of 12p13.2 and 12 centromeres with no loss or gain of 1p36 or 1q25. Smith NM, Chambers SE, Billson VR, Lang I, West CP, Bell JE: Oral teratoma (epignathus) with intracranial extension: a report of two cases. Because their growth is limited, hamartomas are not true tumours and some, such as hemangiomas that occur as birthmarks, may disappear with time. Immunohistochemically, the epithelial components were positive for keratins and EMA, and showed focal positivity for AFP. … Hamartomas are usually caused by a genetic syndrome that affects the development cycle of all or at least multiple cells. of the nasal cavity and paranasal sinuses.
