Palmar Surprise: A Case of Eccrine Poroma with Review of Literature
Abstract
Eccrine poroma (EP) is a benign skin adnexal tumor that originates from eccrine sweat glands. It usually appears as a solitary mass on an extremity, commonly on the hand or foot. However, clinical presentation can be varied, posing diagnostic challenges. This study describes a rare case of ulcerative EP on the palm. It covers the clinical and histological features, the diagnostic and treatment approaches, and the potential for local recurrence or malignant transformation.
