Kaposi's sarcoma is a neoplasm of multifocal origin which manifests primarily as vascular nodules in the skin and other organs.
We report a case of Kaposi's sarcoma of classic type in a 17-year-old boy, who had a 4×5cm sized, dusky erythematous plaque with multiple spots of acupuncture on the left foot for 1 year. Histopathologic examination showed dilated,
bizarre-shaped
vessels, endothelial cell proliferation, and spindle cell formation with vascular slits throughout the dermis. He was treated with 3000 rads of radiation(300 rad per day for 10 successive days). Six months after radiotherapy, gross findings were
much
improved and histopathologic findings showed only fibrosis and hemosiderin deposits in the dermis. (Kor J Dermatol 1993 ; 31(3) : 439-443)
