Carcinossarcoma uterino: relato de um caso com invasão da bexiga, mimetizando mullerianose com transformação maligna / Carcinosarcoma of the uterus: report of a case with invasion of the urinary bladder, resembling mullerianosis with malignant transformation

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.

Tumores müllerianos mixtos malignos uterinos / Uterine malignant mixed mullerian tumors

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.

Extra genital heterologous malignant mixed mullerian tumor of primary peritoneal origin.

The case of an extragenital heterologous malignant mixed müllerian tumor (MMMT) of primary peritoneal origin occurring in a 76-year-old female is presented. A large tumor was seen between the uterus and rectosigmoid occupying the entire pelvis. The uterus, fallopian tubes and ovaries were uninvolved. The tumor was composed of carcinomatous areas showing endometrioid and serous papillary differentiation and sarcomatous areas showing cartilaginous differentiation. The extragenital primary MMMTs of the female peritoneum are thought to originate from the secondary müllerian system. This case is presented for its rarity. To the best our knowledge, this is the first case of extragenital MMMT of primary peritoneal origin in Indian literature.

[Mixed mullerian tumors of uterus - about 25 cases]

The malignant mixed mullerian tumours [MMMT] or carcinosarcoma of the uterus are rare tumours, they represent 1,4% of all uterine neoplasia. They are characterized historically by double components carcinomatous and sarcomatous. We performed a retrospective study about 25 cases of carcinosarcoma of the endometrium, collected in Salah Azaiz Institute over a period of 30 years going from 1970 to 2000. The mean patient age was 60 years, and 68% of patients were menopaused. The metrorrhagia was revealing in 66% of cases. Clinically, an abdominopelvic mass was found in 12% of the cases. The pathological diagnosis was done in 12 endometrial biopsies and 10 biopsies of the tumour exteriorisated by the cervix. Surgery is the mainstay of the treatment. The prognosis remains dismal

Post-irradiation carcinosarcoma of uterus--a case report.

The carcinosarcoma (malignant mixed mullerian tumour) of uterus is an aggressive neoplasm composing of malignant glands in the malignant stroma showing biphasic appearance. A 55 year old woman presented with discharge per vaginum of one month duration. Earlier she was given radiotherapy for squamous cell carcinoma of vulva, six years back. Abdominal examination was insignificant. USG suggested presence of post-radiation effect with uterine mass. Panhysterectomy was done and on histopathology, the diagnosis of carcinosarcoma (heterologous variant) was made. The case is being reported and discussed.

Mullerian adenosarcoma of the uterine cervix.

Sarcomas in the uterine cervix are rare, the incidence being 0.5% to 1% of all cervical malignancies. This is a report of cervical mullerian adenosarcoma, which was encountered in a hysterectomy performed for prolapse. The tumor was composed of benign glandular elements and malignant stromal component, thus justifying its nomenclature. We wish to emphasize the distinctive morphological features of this rare cervical tumor.

Adenosarcoma mulleriano heterólogo en la adolescencia: presentación de un caso clínico y revisión de la literatura / Mullerian, heterologous, adenosarcoma in adolescence: one case presentation and literature review
