A case of multiple pyogenic granulomas

Pyogenic granuloma is a common angiomatous proliferation of the skin. It usually occurs in children and young adults and it develops spontaneously or traumatically. Although some cases of multiple pyogenic granulomas secondary to burn or vascular malformation have been reported in the literature, any case of spontaneous multiple pyogenic granulomas has not yet been reported in Korea. In this report, we present a case of multiple pyogenic granulomas that developed spontaneously on the scalp. A 47-year-old man presented with a 2 month history of multiple erythematous papules on his scalp. He had no other accompanying abnormality or history of trauma on the scalp. Among the papules, one lesion was evaluated. Histologically, the lesion consisted of a polypoid mass of angiomatous tissue that protruded above the surrounding tissue and intact flattened epidermis covered the entire lesion. After biopsy, the remaining lesions were treated by electrocautery. There have been no recurrences at 2 years' follow up.
