Discordant architectural and cytological features in cutaneous sebaceous neoplasms-a classification dilemma: report of 5 cases

Abstract

The authors present a series of 5 cases of cutaneous sebaceous neoplasms having 'benign' architectural features (symmetry, sharp circumscription, smooth borders, pseudoendcapsulation) but which simultaneously displayed atypical cytology including abnormal mitoses, high mitotic rates, and moderate-to-striking pleomorphism including bizarre cells.
