Fine needle aspiration cytologic findings in four cases of pilomatrixoma (calcifying epithelioma of Malherbe).
All cases more or less shared the same microscopic features of basaloid cells, ghost cells, calcification, and foreign body type giant cells, presenting features of a calcifying epithelioma of Malherbe (pilomatricoma) (Figure 1).

The histopathological features were consistent with a diagnosis of pilomatricoma (benign calcifying epithelioma of Malherbe).
Review of world's literature has showed that this was a rare case of a calcifying epithelioma of Malherbe in the pinna.
