Acquired bilateral agminated Spitz nevi in a child with Langerhans cell histiocytosis.

摘要

Multiple Spitz nevi are rare and may occur in agminated, widespread, or dermatomal distributions. Agminated Spitz nevi usually arise in children, presenting on grossly normal, hyperpigmented, or most rarely, hypopigmented skin. We present a child with Langerhans cell histiocytosis who developed bilateral agminated Spitz nevi in the inguinal area. Unusual features included the multifocal distribution, bilateral inguinal location, and co-occurrence with Langerhans cell histiocytosis.
