title: Malacoplakia of the pelvis. Report of a case with cytologic and ultrastructural findings obtained by fine needle aspiration.
abstract: Malacoplakia is a rare granulomatous, inflammatory disease usually diagnosed on a biopsy specimen. Only five cases have been diagnosed by FNA, most of them in the prostate. We report the cytologic and ultrastructural findings in fine needle aspirates of pelvic malacoplakia. The main characteristic of the smears was a richly inflammatory background with abundant, foamy histiocytes containing Michaelis-Gutmann bodies. The results indicate that fine needle aspiration is useful in diagnosing this disease, excluding a neoplastic process and performing follow-up.
