Pyogenic Granuloma

A pyogenic granuloma is an acquired vascular tumor that is commonly found on the skin and mucous membranes in children and adults. The entity is somewhat of a misnomer, as these benign (non-cancerous) vascular growths are neither infectious nor granulomatous. Although the etiology of these lesions is idiopathic (of unknown cause), some specialists hypothesize that they may be an abnormal response to inciting trauma.

The treatment of these lesions is generally straightforward, requiring shave removal and cauterization of the feeding vessels at the base. This leads to resolution of these tumors in the vast majority of cases.
