ABSTRACT
Los tumores mesenquimáticos de la mucosa uterina son un grupo raro, heterogéneo y generalmente agresivo de neoplasias que conduce frecuentemente a una diseminación y muerte temprana. Constituyen menos del 3% de todos los tumores malignos del Tracto Genital Femenino y el 2-7% de las neoplasias malignas uterinas. Presentamos 4 casos de tumores mesenquimáticos diagnosticados en un período de 5 años en el Servicio de Anatomía Patológica del Hospital General de Agudos Carlos G. Durand, analizando su incidencia y haciendo una breve revisión de las características histopatológicas de los mismos
Mesenchymal tumors of the uterine lining are a rare and heterogeneous group of neoplasms, with an agressive behavior leading to an early dissemination and death. They represent less than 3% of all malignant tumors of the Female Genital Tract and 2-7% of uterine malignancies. We report 4 mesenchymal tumors diagnosed throughout a 5 years period at the Department of Pathology Hospital General Carlos G. Durand, analyzing their incidence and making a review of the histopathologic features

Endometrial stromal sarcoma (ESS) is a mesenchymal neoplasm that usually occurs as a primary tumor of the uterine corpus, but rarely arises in other sites, such as the ovary, pelvic cavity, mesentery, omentum and intestine. Herein, we present a rare case of low-grade ESS presented as prevesical mass. A 60-yr-old woman who had undergone total hysterectomy for endometriosis eleven years ago was presented with incidentally detected prevesical pelvic mass. Since malignant transformation of urachal remnants was possible, the mass was suspected to be a urachal tumor. Extraction of the mass was performed, and the histopathologic diagnosis was low-grade ESS. In summary, prevesical tumor is rare but in patients with endometriosis, we suggest endometriosis and its possible malignant changes should be taken into account in the differential diagnosis of prevesical mass.
