ABSTRACT
Introdução: Os carcinossarcomas uterinos são neoplasias infrequentes, correspondendo a apenas 3-9 por cento de todas as neoplasias ginecológicas, representam 48 por cento de todos os sarcomas, e possuem incidência de 8,2 por 1 milhão mulheres/ano. As principais manifestações clínicas são o sangramento vaginal anormal em idade pós-menopausa e dor abdominal. Caracterizam-se morfologicamente por elementos epiteliais e estromais. Podem eventualmente invadir estruturas adjacentes, inclusive a bexiga urinária. Relato do caso: Apresentamos um caso de carcinossarcoma uterino com invasão de bexiga mimetizando mullerianose com transformação maligna. A paciente do sexo feminino de 69 anos apresentava hematuria macroscópica como queixa única. Durante a investigação diagnóstica, após cistoscopia com exame anatomopatológico, foi sugerida a hipótese de mullerianose com transformação benigna. A paciente foientão encaminhada para ressecção cirúrgica da neoplasia. Durante o procedimento cirúrgico, notou-se a existência deuma massa tumoral uterina que invadia a bexiga urinária, e, após análise anatomopatológica, mostrou tratar-se de umcarcinossarcoma uterino com invasão vesical. Conclusão: Manifestações incomuns em doenças com grande potencialde malignidade, além de retardar o processo diagnóstico, interferem diretamente no prognóstico do paciente.

Los tumores müllerianos mixtos malignos o carcinosarcomas son neoplasias poco frecuentes y altamente agresivas que suelen presentarse en pacientes mayores de 60 años, generalmente en forma de metrorragia posmenopáusica y/o presencia de masas uterinas. Entre los factores de riesgo reconocidos está descrita la historia de irradiación previa del área pélvica. Presentamos 3 casos clínicos de pacientes diagnosticadas y tratadas de tumores müllerianos mixtos uterinos malignos, existiendo en todos ellos el antecedente de neoplasias que habían precisado radioterapia pélvica como parte de su tratamiento.
The malignant Mullerian mixed tumors are rare and highly aggressive, these tumors usually occur in women over 60 years and the most common clinical appearance is that of postmenopausal vaginal bleeding or the presence of uterine mass. As a risk factor is described the history of prior irradiation of the pelvic area. We reported the case of three patients with mullerian mixed tumors, in all these cases the patients have a history of cancer who required pelvic radiation as part of their treatment.

Los tumores müllerianos mixtos malignos son neoplasias malignas muy infrecuentes. El sitio más común de su ocurrencia es el tracto genital del sexo femenino, dentro de él aparecen, el cuerpo del útero, el cuello, ovario, y trompas. Caso clínico: se presenta un caso con una gran dificultad diagnóstica tanto clínica, e imagenológica, con confirmación histológica de Tumor maligno mülleriano mixto gigante del cuello y el cuerpo del útero en una mujer postmenopáusica que se presentó con una masa abdominal grande, e historia de radioterapia hace ocho años para un carcinoma del cuello del útero. Al examen médico inicial y a la Tomografía axial computarizada impresionó como un tumor ovárico, durante el acto quirúrgico se observó un tumor gigante, deforme, irregular de cuerpo de útero, v/s sarcoma endometrial estromal , sin embargo, en el examen patológico reveló un tumor mülleriano mixto maligno de cuerpo y cuello de útero. El componente de epitelial maligno era un carcinoma escamoso, con un componente sarcomatoso homólogo. La paciente fue tratada quirúrgicamente. Conclusión: El diagnóstico exacto del Tumor maligno mülleriano mixto del cuello y cuerpo del útero es importante para el tratamiento apropiado del paciente (AU)
Müllerian mixed malignant tumors are very infrequent neoplasms. The commonest site of occurrence is in the female genital tract; inside him the body of uterus, uterine neck, ovary, and tuba uterina appear. Case presentation: a great difficult diagnostic case both clinical and imaging is presented, with histological confirmation of giant müllerian mixed malignant tumor of cervix and body of uterus in a postmenopausal woman who was presented with a large abdominal mass and a radiotherapy history of eight years ago for a uterine neck carcinoma. To the initial medical examination and computerized axial tomography appeared to be an ovarian tumor, during the surgical act appear like giant and deformed irregular uterus tumor, v/s endometrial stromal sarcoma, however, the pathological examination revealed a müllerian mixed malignant tumor of cervix and body of uterus. The malignant epithelial component was a squamous carcinoma with a homologous sarcomatous component. The patient was surgically treated. Conclusion: Accurate diagnosis of cervix MMMT is important for the patients appropriate treatment (AU)

PURPOSE OF REVIEW: Müllerian mixed malignant tumors of the ovary constitute an infrequently encountered group of malignant ovarian neoplasms, which are highly aggressive and respond poorly to treatment. The relatively low number of reported cases and the difficulty of preoperative diagnosis make it difficult to ascertain the biology of these tumors. RECENT FINDINGS: These are mixed, mostly monoclonal tumors, and the predominance of the stromal component aggravates the prognosis. The clinical presentation of these tumors is similar to that of epithelial ovarian tumors, although they tend to manifest themselves at later stages of disease. There are no useful biochemical markers: imaging diagnostic methods (ultrasound, computed tomography, magnetic resonance imaging) do not provide specific data. The staging and primary treatment are always surgical. Survival improves when cytoreduction is satisfactory. Chemotherapy (platinum) can prolong survival, but there are no effective second-line treatments. Radiotherapy is of no help. The prognosis of this cancer is always guarded. Genetic and molecular techniques will be very important in advancing our knowledge of tumoral biology. In order to improve therapeutic results, it will be necessary to design multicenter, cooperative studies including larger numbers of patients. SUMMARY: In clinical practice, treatment options for these tumors are few; a rapid downhill course is the rule rather than the exception.

Malignant mixed Mullerian tumors (MMMTs) are rare neoplasms. We report the clinical, pathologic, and immunohistochemical features of an MMMT primary of uterine cervix. This lesion was composed of a poorly differentiated epithelial component (cytokeratin positive) and a spindle cell component (vimentin positive) with heterologous (myoblastic) differentiation (focal 1A4 positive). There were also cells with neuroendocrine features that expressed S-100 and chromogranin A. Along with a brief review of this amazing neoplasm, some histogenetic concepts relevant to this case are discussed. To our knowledge this is the first report of a malignant mixed Mullerian tumor of the uterine cervix with neuroendocrine differentiation.
