Abstract
|
|
|
Congenital melanocytic nevi occur in approximately 1~3% of newborns and are usually classified according to their size. Giant congenital melanocytic nevi are associated with an increased risk of development of melanoma. Thus, careful follow-up is mandatory. Generally congenital melanocytic nevi are round to oval in shape and have a regular, smooth, and well-demarcated border. Histopathologic finding shows junctional nevi, compoud nevi or dermal nevi pattern. We report a case of congenital melanocytic nevi with unusual cutaneous manifestation as an oval shaped patch with an irregular border and speckled pigmentation on the left calf of a 25 year-old female. The histologic findings revealed diffuse infiltration of the dermis by nevomelanocyte.
