title: Unusual metastatic spread of a malignant eccrine poroma.
abstract: Malignant eccrine poroma is a rare skin tumor which commonly presents as verrucous plaques or polypoid growths. We report an 83 year old male who presented with an ulcerating eccrine poroma on the left arm. Though the tumor was excised with wide margins, axillary lymphadenopathy due to regional metastasis developed four months later, followed by lymphangitic cutaneous spread at six months. Though the prognosis for this tumor is better than previously thought, it still must certainly be considered potentially fatal.
