Pyogenic granuloma.

Pyogenic granuloma (PG) is an acquired vascular lesion of the skin and mucous membranes common to the pediatric age group. PG appears as a solitary red nodule on the head or neck. The nodule is prone to hemorrhage, and bleeding is often refractory to pressure. The etiology of PG is unknown, but proposed agents include trauma, infection, and preceding dermatoses. Several surgical treatments are available with variable cosmetic results and recurrence rates.
