title: Atypical fibroxanthoma masquerading as pyogenic granuloma.
abstract: An atypical fibroxanthoma on the ear of a 82-year-old man appeared clinically as a pyogenic granuloma. Histopathologically, the lesion had been interpreted as a malignant melanoma before its true nature was identified. Familiarity with this cutaneous pseudomalignant growth is essential to prevent radical surgical procedures.
