Abstract

An eccrine poroma is a solitary tumor arising from the eccrine duct epithelium in the epidermis. The lesions commonly occur on the sole of the foot, the hands, and occasionally on the nose, eyelids, neck, and chest. We report a patient who presented with a slow-growing nodular lesion over her left cheek, prompting a diagnosis of basal cell carcinoma or keratoacanthoma. Biopsy from the nodule revealed a well-defined epidermal tumor with uniform small cuboidal cells with rounded deeply basophilic nuclei, few narrow ductal lumina, and occasional cystic spaces confirming the diagnosis of an eccrine poroma.

Keywords: Eccrine poroma; intercellular bridges; poroid cells.
