Pigmented poroma with unsusual locatin and dermatoscopic features
Keywords:
poroma, dermatoscopy, basal cell carcinoma, histopathology, pigmentationAbstract
Poroma is a benign adnexal neoplasm with “poroid”/ductal differentiation that mimics benign and malignant skin tumors. Histopathology shows circumscribed proliferation of poroid cells intermingled with a variable number of cuticular cells. We report a case of pigmented poroma located on the face that simulated clinically and dermatoscopically a pigmented basal cell carcinoma. The features of pigmented and non-pigmented poromas were revisited in order to assist in the diagnosis.
