Abstract
|
|
|
Clinically, benign juvenile melanoma (BJM) is a benign news-cell tumor and arise predominantly in children. The lesion usually is solitary and is encountered most commonly on the face and extremities. In. most instances the lesion consists of a dome-shaped, small nodule. The histologic picture often closely resembles that of a malignant melanoma and there is no doubt that prior to its recogftition 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. Histologic pictures show considerable junctional activity. In the upper dermis edema and ectasia of the various vascular elements are present. The re Tus cells are pleomorphic. They are mostly spindle-shaped and are arranged mostly in fairly well circumscribed nests. Giant cells are frequently 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 reports of BJM in Korea, based on our own review.
