Diagnosis of atypical fibroxanthoma--a case report.

Atypical fibroxanthoma has a wide spectrum of histological and cytological appearances. One recently described variant is atypical fibroxanthoma with touton type giant cells. We also came across this case in a 24 year old male student who presented with a sub epidermal nodule on the right shoulder for the last one year. The lesion was aspirated, it should spindle shaped cells, giant cells, and collagen. Giant cells had multiple vacuoles and pink colored granules in their cytoplasm. He was diagnosed as atypical fibroxanthoma. The tumor was excised and histopathology confirmed the diagnosis. Complete excision was curative.
