A 39-year-old woman with multiple acquired melanocytic nevi was regularly evaluated in our Department of Dermatology using digital dermoscopy. In one of her routine visits, dermoscopy revealed that many of her nevi and seborrheic keratoses had changed since her last visit. Multiple yellow-brownish blotches now appeared in almost all the lesions, and these blotches varied greatly in size. In the flat lesions, a few small globules of yellow-brownish pigment were noted scattered over the nevi, while in the raised lesions appeared multiple larger blotches of the same color, similar to, but larger than, comedolike or pseudofollicular openings (Figure 1). However, no clinical changes were noted.
