Primary vulvar melanoma with satellite metastasis: dermoscopic findings

Abstract

A 79-year-old woman presented with a 1-year history of a pigmented nodular lesion on the left labium minor. Histopathology of the nodule led to a diagnosis of metastatic melanoma. A pigmented flat lesion on the inner side of the left labium major was also biopsied and was found to be a superficial spreading melanoma. The dermoscopic findings of primary and metastatic vulvar melanoma which simultaneously occurred in the same patient are described. Dermoscopy revealed a homogeneous pattern associated with linear irregular vessels in the metastatic nodule, while irregular globules and streaks were seen in the primary melanoma.
