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. © 1995 Wiley- Liss, Inc.
