“…Rare examples occurring outside the CNS include one behind the urinary bladder (7) and another as a component of an ovarian mature cystic teratoma (11). Thus, proximity to the subventricular zone is not requisite to the diagnosis.…”

“…In addition, the clinical course and the low proliferative index are clearly inconsistent with the highly malignant features of PNET. A further differential diagnosis is a teratoma of the pelvis with neuroepithelial differentiation [7]. However, sacrococcygeal teratomas tend to manifest in infancy [8] and, in the present case, additional structures indicating a teratoma were not present.…”

“…In the literature, cases of extraventricular neurocytomas occurring in the central nervous system [3,9] and also in unusual locations like the cauda equina [12] have been well documented. Hirschowitz et al [7] described a neurocytoma arising within a mature cystic teratoma of the ovary. Primarily due to the pelvic origin of the present case, the differential diagnostic exclusion of soft tissue tumors had to be performed to prove immunonegativity for vimentin and pan-keratin.…”

Central neurocytoma represents a rare neoplasm of the central nervous system with advanced neurocytic and sometimes focal lipomatous differentiation, a low proliferative potential and a favorable prognosis depending on the efficiency of surgical resection. This entity has been described as an intraventricular tumor near the foramen Monroi. Here, we report a case of a 21-year-old male with peripheral neurocytoma. Using computed tomography, a tumor of unknown origin was located behind the bladder. After complete surgical resection of the tumor, histologically small uniform cells, zones of fibrillarity and neuropil-like islands were seen. Immunohistochemistry revealed positivity for the neuronal markers synaptophysin, neuron-specific enolase and neurofilaments. Vimentin, pan-keratin, desmin, chromogranin, CD-99 and glial fibrillary acidic protein were immuno-negative. A low proliferation rate (1-2%) was found. Several case reports described extraventricular central neurocytomas. A sole publication documented a peripheral neurocytoma arising within a mature cystic teratoma of the ovary. To our knowledge, this is the second reported case of a neurocytoma outside the central nervous system, indicating that this entity may also occur infrequently in peripheral tissues.

“…Literature data suggest that the presence of brain tissue in mature teratoma is rare. (21,22,23) Although the HP appearance was highly suggestive for the diagnosis of carcinosarcoma associated with mature teratoma, we performed immunohistochemical testing for confirmation of the mixed character of the malignant proliferation (for the carcinomatous component AE1 / AE3, CA-125, ER, WT1, Although we have no data to prove the existence of a previously asymptomatic ovarian mature teratoma we believe that the coexistence of mature teratoma elements with malignant ones in the peritoneal and ovarian tumor formations support the diagnosis of malignant mature teratoma.…”

RezumatTeratom matur ovarian bilateral asociat cu carcinosarcom -asociere întâmplãtoare sau determinism etiopatogenic? -prezentare de caz Carcinosarcomul este o forma rarã de cancer ovarian cu origine mixtã, iar asocierea sa cu teratomul matur este extrem de rarã. Prezentãm cazul pacientei T.M. în vârstã de 67 ani, internatã în clinicã în 15.05.2016, F.O. 4877 pentru creaeterea în volum a abdomenului. La internare, pacienta afebrilã, conaetientã, cooperantã, echilibratã cardio-respirator, cu abdomen destins de volum, matitate accentuatã pe flancuri, semnul valului pozitiv, bioumoral în limite normale cu excepåia: acid uric seric = 6.64 mg/dl, glicemie sericã = 113.7 mg/dl, proteine serice totale = 8.65 g/dl, raportul albuminã/globulinã subunitar, CRP 33.63 mg/l, sideremie 51 ug/dl, CA 125 = 588.4 UI. Ecografia abdominalã: cantitate mare de lichid decliv aei perihepatic aei multiple formaåiuni tumorale cu transformare chisticã la nivelul abdomenului aei pelvisului. Examen CT descrie multiple mase tisulare localizate intraperitoneal abdomino-pelvin, manaeonate în epanaeament lichidian, infiltrative, cu efect de masã pe lumenele digestive, fãrã obstrucåie vizibilã CT. Tratamentul chirurgical a constat în evacuarea lichidului de ascitã, excizia formaåiunilor tumorale din marele epiploon, a formaåiunilor tumorale din ligamentul gastro-colic, epiploonectomie, anexectomie bilateralã aei histerectomie totalã. Evoluåie postoperatorie simplã. Examenul histopatologic confirmã diagnosticul de carcinosarcom ovarian bilateral asociat cu teratom matur tridermic (prezenåa zonelor de åesut cerebral, asociat cu åesut cartilaginos, epiteliu de tip tranziåional, epiteliu de tip tubar, stromã de tip endometrial, åesut adipos). IHC confirmã compatibilitatea cu diagnosticul de carcinosarcom ovarian (tumorã malignã mixtã mullerianã). Pacienta a urmat polichimioterapie adjuvantã. Asocierea teratomului cu elemente carcinosarcomatoase conferã cazului un prognostic infaust. Cuvinte cheie: teratom matur, carcinosarcom ovarianAbstract Carcinosarcoma is a rare form of ovarian cancer with mixed origin, and its association with mature teratoma is extremely rare. We present the case of patient T. M. aged 67, admitted into our clinic on the 15/05/2016, F.O. 4877 for the increase of the abdominal volume. On admission, the patient was afebrile, conscious, cooperative, cardio-respiratory balanced, having the abdomen distended in volume, sharp dullness in the flanks, positive wave sign bioumoral within normal limits except: uric acid = 6.64 mg / dL, serum glucose = 113.7 mg / dl, serum total proteins = 8.65 g / dl, the albumin / globulin subunit, CRP 33.63 mg / l, sideremia 51 ug / dl, CA 125 = 588.4 IU.
