title: Uterine adenosarcoma detected by Papanicolaou smear: a case report.
abstract: Adenosarcoma is a rare uterine biphasic tumor composed of benign epithelial elements and a sarcomatous stroma. Although it is well described histologically, its cytological features are rarely mentioned in the literature. We describe a case of uterine adenosarcoma that was first detected by Papanicolau (Pap) smear. Numerous crowded clusters of spindle cells were present within a bloody background, as well as a few smaller, dyscohesive groups with cells showing high N:C ratio and oval to round nuclei with coarse chromatin and small nucleoli. A few nuclear grooves were identified. Adenosarcomas are rare lesions but should be considered in the differential diagnosis when spindled cells are noted in a pap smear.
