Pilomatrixoma: a description of two cases diagnosed by fine-needle aspiration.
The present work reports on the findings obtained by fine-needle aspiration of two pilomatrixomas located on the upper limbs whose diagnosis was confirmed histologically. In both cases, the cytology disclosed a proliferation of small round basaloid cells that were dispersed and grouped in clusters together with squamous cells and abundant multinucleate giant cells. The differential diagnosis with other neoplasms is discussed.
