title: [The atypical fibroxanthoma].
abstract: A 84-year-old female patient suffering from atypical fibroxanthoma is presented. A diagnosis of malignant melanoma or a cutaneous metastasis from an unknown primary tumor was suspected. The final diagnosis was established by immunohistological studies showing a strongly positive reaction to vimentin and a negative reaction to S-100 protein and cytokeratin.
