hamartoma vs teratoma

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. A hamartoma resembles a neoplasm, but in most cases, it does not show any tendency to evolve into one. It is noteworthy that malignant teratomas usually do not exhibit the carcinosarcomatous features, present in SNTCS [3] although it is certainly recognized that a sarcomatous component might be present in some malignant germ cell tumors [32]. 10.1016/S0022-3468(98)90103-8. Br J Oral Maxillofac Surg. hamartoma versus neoplasm). About 5–8% of all solitary lung nodules and about 75% of all benign lung tumors, are hamartomas. 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. Google Scholar. By using this website, you agree to our These ducts were lined by cuboidal or low columnar epithelium that frequently was transformed into squamous-type lining. (A): Gross appearance of the epignathus with tongue-like structures with the blunt border and skin-like surface. 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. volume 8, Article number: 8 (2008) Google Scholar. The tumors are reported in patients of diverse ages, with significantly varied clinical signs. These symptoms will vary depending upon the location of the hamartoma. Int J Pediatr Otorhinolaryngol. No transphenoidal intracranial extension of the tumor was found. Teratomas are histologically classified as either mature or immature, where immature elements consist mainly of primitive neuroglial tissue and neuroepithelial rosettes. Below are the links to the authors’ original submitted files for images. The finding of trisomy 12 in our case of SNTCS supports the hypothesis that SNTCS has the germ cell origins though Salem et al [6] recently reported three cases of SNTCS with no amplification of chromosome 12p, thus questioning the germ cell origins of SNTCS. The majority of thyroid teratomas are easily recognizable as such on clinical, radiographic, and pathologic grounds. Hamartomas can look similar to cancer on imaging studies, and for this reason, can be very frightening. 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. A hamartoma is a mostly benign, 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. SGAT exhibits benign behavior and no recurrences after complete surgical resection were reported in the literature [26]. A hamartoma resembles a neoplasm, but in most cases, it does not show any tendency to evolve into one. Ann Diagn Pathol. Five months later she presented with complaints of sinus symptoms and CT scan identified a "large right nasal polyp". p53 stained approximately 10% of the neuroectodermal components. Cytogenetic analysis revealed chromosomal abnormalities only in the case of SNTCS that showed trisomy 12 and 1p deletion. 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. This article is published under license to BioMed Central Ltd. [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. 2007, 36: 534-538. Michal M, Sokol L, Mukensnabl P: Salivary gland anlage tumor. The histologically mature (benign) congenital oronasopharyngeal teratoma (epignathus) caused death from upper airway obstruction in a neonate. Salivary gland anlage tumor [SGAT, also described as congenital pleomorphic adenoma] is a very rare, probably hamartomatous tumor of the nasopharynx of neonates [20]. 2007, 31: 1356-1362. Well defined fibrous tumor, ducts separated by connective tissue. 0. A teratoma is a rare type of tumor that can contain fully developed tissues and organs, including hair, teeth, muscle, and bone. We correlate their presenting clinico-pathological features and compare histologic and cytogenetic features in an attempt to elucidate their pathogenesis and biologic potentials. 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 hypothalamic hamartoma (HH) is a rare, benign (noncancerous) brain tumor or lesion of the hypothalamus. 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. Send thanks to the doctor. Herrmann BW, Dehner LP, Lieu JEC: Congenital salivary gland anlage tumor: a case series and review of the literature. One general danger of hamartomas is that they may impinge into blood vessels, resulting in a risk of serious bleeding. 10.1001/archotol.134.6.592. 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. You can classify teratoma into two types namely the cancerous and non-cancerous teratoma. The great majority of them form in the connective tissue on the outside of the lungs, although about 10% form deep in the linings of the bronchi. hamartoma versus neoplasm). Cite this article. However, when immature elements predominate, extraskeletal Ewing sarcoma, small cell carcinoma, lymphoma, and rhabdomyosarcoma enter the differential diagnosis. Histopathology. - Duration: 0:56. Thus their origins remain largely unknown. Pediatrics. 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. 2006, 19: 377-379. In this article, I'll only try to mention the main tricky differences between them. It is a part of any tissue that either grows faster or without the usual organization of its neighbor cells. Medical records and histopathological reports were retrospectively analyzed. Cite this chapter as: Houser C.M. 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. Bussey KJ, Lawce HJ, Olson SB, Arthur DC, Kalousek DK, Krailo M, Giller R, Heifetz S, Womer R, Magenis RE: Chromosome abnormalities of eighty-one pediatric germ cell tumors: Sex-, age-, site-, and histopathology-related differences – A Children's Cancer Group Study. 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]. LSI ETV6 (TEL) probe at 12p13 and a homebrew probe set for ETV6 and CEP12 were unsuccessful. Histologically, SNTCS is composed of various tissues including epithelial, mesenchymal, and neural elements including teratoid elements. 10.1097/PAS.0b013e318033c7c4. A clinicopathologic study of 20 cases. 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. Cystic Teratoma. The diagnosis of mature cystic teratoma at CT and MR imaging is fairly straightforward because these modalities are more sensitive for fat (23). Neoplasm.

Imaging studies of the chest did not identify a cause. Hamartomas are usually caused by a genetic syndrome that affects the development cycle of all or at least multiple cells. This characteristic distinguishes SNTCS from other malignant germ cell tumors. 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 was excised and submitted for pathologic examination. Trisomy 12, as a primary or secondary event, is a well known cytogenetic abnormality occurring in majority of malignant germ cell tumors [1, 27]. Possible trisomic or tetrasomic zygote rescue in fetal teratoma with an additional isochromosome 1q. SGAT was first described by Har-El et al [21] in 1985, and a series of nine cases was described by Dehner et al in 1994 [20]. The search utilized the pathology files of Yale-New Haven Hospital using CoPath laboratory information system. A tumor was visible through the slightly opened mouth appearing as a tongue-like structure with a blunt border and skin-like surface. A hamartoma is a focal lesion that resembles a neoplasm, grossly and even microscopically, ... A mature teratoma also enters the differential, as it may occur in the mediastinum. 1 doctor agrees. 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].

MRI revealed a large polypoid tumor mass eroding through the cribriform plate of the right ethmoid sinus into the cranial cavity. 1993, 13: 945-952. A hamartomatous SGAT was diagnosed in a 12 month old male and prompt appropriate treatment avoided potentially life-threatening severe respiratory distress and feeding difficulties [26]. The cancerous presence depends on the location of the teratoma in your body. Moore SW, Satgé D, Sasco AJ, Zimmermann A, Plaschkes J: The epidemiology of neonatal tumors. Histopathological features of SGAT include the presence of the stratified squamous epithelium that extends into a loose, myxoid stroma forming a submucosal network of branching tubular structures (tubular to cord-like epithelial structures). If the diagnosis can be established, future cases may consider alternative treatment approaches including a recently developed EXIT procedure to allow for survival of the newborn. An 85 year old African American female presented to her primary care physician with complaint of spitting up blood. Areas with necrosis and cystic degeneration might also be present [22]. A clinicopathologic, immunohistochemical and ultrastructural study of nine cases. They did not consider hamartoma as a solitary lesion and, apart from Carney's triad, tried to define a "pulmonary hamartoma syndrome." Toggle navigation. In our cases, neither the SGAT nor epignathus carried such cytogenetic aberrations. The different elements blended morphologically into one another. 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. Additional growths can form in many parts of the body, especially in bones, CNS, the eyes, the genitourinary tract, the GI tract, and mucosa. 2006, Berlin, Heidelberg: Springer, 50-64. Part of the tumor consisted of mature neuroglial tissue covered by leptomeningeal-like layer, rich in blood-filled capillaries. hamartoma versus neoplasm). A hamartoma is a tumor-like growth that is benign. 10.1148/rg.251045156. Hamartomas can look similar to cancer on imaging studies, and for this reason, can be very frightening. 2005, 5: 210-222. Hamartomas result from an abnormal formation of normal tissue, although the underlying reasons for the abnormality are not fully understood. The leptomeningeal-like structures were lined by thin epidermal layer which was in continuity with epidermal skin layer of main part of the tumor. View Teratoma PPTs online, safely and virus-free! Moreover, resection is usually difficult, as the growths are generally adjacent to, or even intertwined with, the optic nerve. Because a hamartoma typically lacks elastic tissue, it may lead to the formation of aneurysms and thus possible hemorrhage. It usually occurs when an abnormal amount of normal cells collect on healthy tissue. Oosterhuis JW, Looijenga LHJ: Testicular germ-cell tumours in a broader perspective. 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]. 2007 Jun;62(6):600-2.

Immunohistochemically, the epithelial components were positive for keratins and EMA, and showed focal positivity for AFP. While malignant tumours contain poorly differentiated cells, hamartomas consist of distinct cell types retaining normal functions. It primarily affects adults (average age 60 years) with only 87 cases reported in the available literature [3–7]. PubMed  2003, 18: 26-28. Both teratoma and seminoma are germ cell tumors, which share some of the similar characteristics, but they do differ in many ways. The case reports were shared with Creighton's University Institutional Review Board; it is however the policy of this Board not to review case reports. Pathology. The incidence of teratoma is higher in females, but the risk of malignant teratoma is higher in males [10]. About 50% of such cases manifest abdominal pain, and they are often associated with hematologic abnormalities and spontaneous rupture. 2004, 43: 687-691.

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]. Carrizo F, Pineda-Daboin K, Neto AG, Luna MA: Pharyngeal teratocarcinosarcoma: review of the literature and report of two cases. 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). Petechiae were present on the anterior chest and neck region. Most are asymptomatic, but they can cause dyspepsia or upper gastrointestinal bleeding. Other tumors that may be considered include primarily olfactory neuroblastoma, squamous cell carcinoma, adenocarcinoma, neuroendocrine carcinoma, sarcoma, blastomatous tumors with teratoid features, and craniopharyngeoma [3, 33, 34]. 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. She was referred to the hospital because ultrasound revealed a large mass in the mouth of the live female fetus filling the oral cavity but not protruding out of the mouth. 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.
