A Case of an Unusual Eccrine Poroma on the Left Forearm Area

Abstract

A 40-year-old woman presented with an asymptomatic red to brown colored walnut-sized, dome shaped, hemorrhagic, crusted nodule on the left forearm. There was no previous history of trauma to the area. The first impression of this case was a vascular tumor or malignant lesion due to the large size and bleeding tendency. However, the final diagnosis, according to histologic and immunostaining methods, was a benign eccrine poroma that occurred on the left forearm, which is an unusual area for such a lesion. The tumor was excised and no recurrence was noted when she was examined 24 months later.
