Eccrine poroma (EP) is a benign adnexal neoplasm that clinically presents in a wide range of forms. Misdiagnosis is frequent among malignant and vascular skin tumors. We present the case of a man that consulted at our dermatologic clinic because of a longstanding pigmented tumoral mass on the abdomen. Dermatoscopy showed some blue-gray nests, peripheral and irregular blood vessels, dark spots and erythematous borders. The lesion was excised and diagnosis of pigmented eccrine poroma was confirmed by histopathologic findings. Dermatoscopy is a noninvasive and standardized technique that can help in the diagnosis of EP. Given the advances in dermoscopy and recent descriptions on dermoscopic features of both pigmented and non-pigmented EP, lesions might be better characterized. A comprehensive search of the literature on the topic was conducted using PubMed database. In conclusion, multiple dermoscopic patterns of EP have been published to date and might probably guide towards diagnosis of EP, however, histopathology is still the gold standard.
