Eccrine Poroma: A report of five cases

ABSTRACT

The eccrine poroma was described first by Pinkus et al. in 1956 as a subgroup of benign solid hidradenoma with the histologic structure resembling acrosyringium. The histologic appearance of eccrine poroma greatly resembles that of seborrheic keratosis and basal cell carcinoma. But the clinical lesion is fairly unique and the tumor is most commonly found almost exclusively on the foot, in the skin of the plantar surface. During the past four years, the authors experienced five cases of eccrine poroma which were diagnosed by histopathological examination of the tumor mass. All the cases occurred in the sole and lateral sides of the foot as well. Clinical and pathological features were reviewed and a brief review of the literatures was done.
