A case of adenosarcoma arising from the uterine cervix of a 55-year-ol
d female who complained of vaginal discharge is reported. A polyp, 6 x
2 x 1.5cm in size, identified in the cervical canal was clinically di
agnosed as benign cervical polyp and resected, Histologically, the pol
yp was composed of benign epithelial components and sarcomatous stroma
wherein periglandular hypercellularity and some mitoses including aty
pical ones were noted. Immunohistochemically, stromal cells were posit
ive for muscle-type actins, desmin and estrogen receptor, Adenosarcoma
is a rare, biphasic tumor of the uterus and usually presents as a pol
ypoid mass in the endometrial cavity. When they arise from the cervix,
adenosarcomas may be confused with benign cervical polyps clinically
and pathologically. As the former often recurs, microscopic differenti
ation is crucial for further treatment.
