title: Cytological Features of Palisaded Mammary-Type Myofibroblastoma.
abstract: Palisaded mammary-type myofibroblastoma is a rare variant of benign stromal spindle cell tumor whose histological features are well known. Nevertheless, no cytological features have been reported to date. In this article, we describe the cytological features of a case of palisaded mammary-type myofibroblastoma in which a preoperative fine needle aspirate was obtained. Smears were moderately cellular, characterized by clusters of spindle cells, disposed in a parallel fashion and immersed in myxoid background. Although the lesion is rare, it is worth distinguishing from benign and malignant spindle cell tumors.
