It occurs in the older age group, usually in the setting of marked solar elastosis on the head and neck. Atypical fibroxanthoma is a malignant skin tumor with histologic features similar to those of undifferentiated pleomorphic sarcoma, but lacking its more aggressive behavior. The tumor is composed of pleomorphic cells with hyperchromatic nuclei and abundant cytoplasm, commonly arranged in a spindle c …. studies. Atypical fibroxanthoma most commonly presented as a solitary, non- specific nodule or ulceronodule on exposed skin of the face in the elderly.
