“…6,7 Only 2% of adenosarcomas arise in the cervix, with fewer than two dozen cases documented so far in the literature, however only two cases of MASO are reported in the uterine cervix and none of them had heterologous elements. 4,5 Since the proportion of the glandular component to the sarcomatous component in usual adenosarcomas can vary from one area of the tumor to another, and focal areas within an otherwise typical adenosarcoma may contain rare or no glands, the diagnosis of MASO must be rendered only when a pure sarcoma, similar to, or of a higher grade than that of the underlying adenosarcoma, accounts for at least one-quarter of the tumor after thorough histological sampling of the hysterectomy specimen. 3 Although MA is regarded as less aggressive, and of lower malignant potential than other malignant mullerian mixed tumors, some unfavorable prognostic factors have been listed for a MASO, high mitotic rate, heterologous elements, deep myometrial invasion, necrosis, and extrauterine spread.…”
