Fine Needle Aspiration Cytology of Pilomatricoma

Abstract

Pilomatricoma is a common benign lesion of hair bearing skin. Fine needle aspiration cytology of a pilomatricoma case is presented. In Giemsa stained smears clusters of basaloid cells adjacent to multinuclear giant cells, occasional calcium deposits and a prominent inflammatory background were present. Ghost cells and intermediate cells, reported in many cases, were lacking. Lesion was histologically confirmed. Basoloid cells with foreign body giant cells in an inflammatory background were helpful in excluding malignant lesions.

Pilomatrikomanın İnce İğne Aspirasyon Sitolojisi

Öz

Pilomatrikoma saçlı derinin sık görülen bir lezyonudur. Bir pilomatrikoma olgusunun ince iğne aspirasyonunu sunuyoruz. Giemsa boyalı yaymalarda inflamatuar zeminde bazaloid hücre kümeleri, bunların komşuluğunda multinükleer dev hücreler, nadir kalsiyum çöküntüleri görülmüştür. Genelde görülenin aksine gölge hücreleri ve intermedier hücreler bu olguda izlenmemiştir.Lezyon total eksize edilerek histopatolojik incelenmesi yapılmıştır. İnflamatuar zeminde yabancı cisim dev hücreleri ile beraber görülen bazaloid hücreler malign lezyonlardan ayırıcı tanıda önemlidir.
