Atypical fibroxanthoma is a rare mesenchymal tumor of intermediate malignancy. It is currently considered a superficial variant of undifferentiated pleomorphic sarcoma. It mostly affects elderly patients with a history of photo damage. The prognosis is favorable with the complete removal of the lesion. Exhibits low rates of metastasis. We present the case of a patient with symptoms, histology and immunostaining compatible with atypical fibroxanthoma. The interest of this presentation is based on the low documented prevalence of this pathology in adulthood, without evidence of infiltrative participation of bone-marrow tissue in evolutionary control.
