A Case of Pyogenic Granuloma-like Lesion by Trauma of Tied-Up Nevus

Pyogenic granuloma is a benign vascular, inflammatory proliferation that appears following minor trauma in children and young adults. The exact pathogenesis of pyogenic granuloma is unknown, but its formation is closely related to minor trauma, chronic irritation, and hormonal influences. A 52-year old woman visited us with a protruding nodule on the right zygoma area. The nodule was pedunculatedby trauma of tied up nevus. Based on the histological finding, we diagnosed post-traumatic pyogenic granuloma like lesion developed within melanocytic nevus.
