Large plaque-type blue nevus with cellular nodules: a rare unrecognized melanocytic tumor

E. Dika, A. Patrizi, M. Lambertini, P. A. Fanti, C. Baraldi, B. Corti
A 24-year-old Caucasian woman referred to us due to the modification of a congenital skin lesion in her right scapular area over the past 10 months. Physical examination disclosed multiple blue/whitish nodules arising on a bluish oval plaque, 6 cm in maximum diameter (fig. 1). The patient's personal and family medical history were unremarkable and negative for melanoma and non-melanoma skin cancers. The entire lesion was totally excised. Microscopy revealed a multifocal dermal proliferation of fusiform and dendritic melanocytes arranged in irregular nodules characterized by many individual foci with the histologic appearance of common blue nevus involving the reticular dermis (fig. 2a-2b).
