Abstract
- A poroma has been thought to be derived from the peripheral cells of the eccrine duct. Nevertheless, there are some cases with sebaceous, follicular and apocrine differentiation, suggesting a possible apocrine origin. Herein, we report a 62-year-old man presented with a nodule surrounded by brownish plaque with hyperpigmented margin on the buttock for several months. Histopathologic examination revealed cords and broad columns of uniform poroid cells with sebaceous differentiation and melanin pigment.
