Giant cerebriform intradermal melanocytic nevus
A 43-year-old woman presented with a large brownish-yellow raised lesion on the dorsal aspect of her left hand which was present since birth. Examination revealed a large cerebriform plaque measuring 11.0 × 9.0 × 3.0 cm [Figure 1], the surface of which seemed studded with hundreds of pebble-like, brownish-yellow lesions of varying sizes, with a soft and smooth texture. The remaining skin and appendages did not show any abnormality. A histopathological examination revealed solitary and variably-sized clusters of nevus cells scattered in the dermis, containing a heterogeneous amount of melanin. The patient was advised excision of the lesions.
