Abstract

Clinically, benign juvenile melanoma (BJM) is a benign nevus-cell tumor and arise predominantly in children. The lesion usually is solitary and is encountered most commonly on the face and extremities. In most mstances the lesion consists of a dome-shaped, srnall nodule. The histoIogic picture often closely resembles that of a maIignant melanoma and there is no doubt that prior to its recognition as an entity by Spitz in 1948 many cases were misdiagnosed as malignant melanoma. A case of benign juvenile melanoma in 23-year old male is described with brief review of literatures. Hisr.ologic pictures show considerable junctional activity. In the upper dermis edema and ectasia of the various vascular elements are present. The re:us cells are pleomorphic. They are mostly spindle-shaped and are arranged mostly in fairly well circumscribed nests. Giant cells are frequentIy observed. Melanin is scanty and mitotic figures are absent. These are typical histologic pictures of the BJM, To our knowledge, there have been no prior repots of BJM in Korea, based on our own review.
