A Case of Atrophic Variant of Dermatofibrosarcoma Protuberans / 대한피부과학회지

ABSTRACT

Atrophic dermatofibrosarcoma protuberans is a rare variant of DFSP, which presents as a depressed violaceous scar like lesion with atrophic plaque. Although atrophic DFSP is identical to classical DFSP in location, treatment, prognosis and histology, clinical diagnosis is sometimes difficult for the atrophic lesion. We report a 36-year-old male presented with asymptomatic firm violaceous depressed atrophic lesion and a skin colored almond shaped, subcutaneous nodule on the left subclavicular area. Histopathologically the tumor shows the spindle-shaped cell arranged in cart wheel pattern. The tumor cells were stained positively for CD 34 on immunohistochemical stain.
