ABSTRACT
@#We report a case of a 33-years old, nulligravid, diagnosed with mullerian adenosarcoma with sarcomatous overgrowth (MASO), who presented with vaginal bleeding and recurrent endometrial polyp. MASO is a rare type of uterine sarcomas, it is a variant of adenosarcomas with poor prognosis. The index patient underwent primary surgical management with lymphadenectomy with a final stage of IC. Histologic diagnosis was Mulllerian adenosarcoma with sarcomatous overgrowth. A panel of immunostaining for estrogen receptors, progesterone receptors and CD 10 showed diffused positivity for the hormones with loss of CD 10 which is consistent with MASO. The rarity of MASO has a distinctive histologic features which merits meticulous sectioning as the clinical course and management vary. It has a poor prognosis due to its short and fast course of the disease.

Mullerian adenosarcoma is a rare biphasic malignant neoplasm of cervix characterized by an admixture of benign epithelial elements and a malignant sarcomatous stromal component, which may be either homologous or heterologous. Mullerian adenosarcoma with stromal overgrowth (MASO) in an aggressive variant of adenosarcoma, which is extremely rare with only two such cases reported till date. In this report, we present a case of MASO of cervix with heterologous elements in a 55/F presenting with postmenopausal bleeding. As it commonly simulates clinically and radiologically as benign cervical polyp, the gynecologists and pathologists should be aware of this extremely rare entity presenting with aggressive clinical course.
ABSTRACT
Purpose To investigate the clinicopathologic characteristtics, immunophenotype and differential diagnosis of uterine adenosarcoma with sarcomatous overgrowth. Metheds The clinicopathological data of 4 cases of uterine adenosarcoma with sarcomatous overgrowth were collected, the histopathologic and immunohistochemical features were investigated, and the rele-vant literatures were also reviewed. Results All of tumors were arised from the endometrium with complains of postmenopausal vaginal bleeding or prolonged menstrual period. There is a poly-poid nodular in the uterine cavity with a pedicle or no pedicel, or rough endometrium. On the cut surface, the tumor was fish-like without distinct from the surrounding tissue. Light microsco-py show the tumors were composed of benign glands and malignant mesenchymal components, the sarcomatouscomponents ac-counted for over 25％. In 4 cases, 2 cases had heterologous com-ponent of rhabdomyosarcoma. The component of sarcomatous were positive for vimentin and CD10. The heterologous component of rhabdomyosarcoma were positive for desmin, MyoDl, and Myogenin.3 cases were died at in 5, 10, and 19 months after operation, 1 patient was disease free survival for 3 months. Conclusion Uterine adenosarcoma with sarcomatous overgrowth has a bad prognosis.
ABSTRACT
Mullerian adenosarcoma is a rare biphasic malignant neoplasm of the cervix characterized by an admixture of benign epithelial elements and a malignant sarcomatous stromal component, which may be either homologous or heterologous. An aggressive variant of adenosarcoma, mullerian adenosarcoma with sarcomatous overgrowth (MASO) is extremely rare, with only two such cases being reported in the English literature to date. In this report we present a case of MASO of uterine cervix with heterologous elements in a 15-year-old unmarried girl presenting with foul smelling menstrual bleeding and passage of fleshy masses. Because MASO with heterologous elements seems to appear at the earliest stages of reproductive lifespan in women, and have an uncertain malignant potential, gynecologists and pathologists should be aware and think about the possibility of this tumor.
