An eccrine poroma is a solitary neoplasm composed of group of benign eccrine ductal epithelial cells. Although the most common site of the eccrine poroma is the sole or hand, it can also occur on the nose, eyelids, neck and chest as well. We report a patient who presented with slowly growing nodule on the right ear helix. Initially the lesion was clinically thought to be a keloid or a pyogenic granuloma. However, the skin biopsy specimen revealed a relatively well-defined epidermal anastomosing tumor with monomorphous small cuboidal cells containing round basophilic nuclei throughout the epidermis layer and turned out to be an eccrine poroma.
