HIGH-POWER LASER REMOVAL OF A VASCULAR LESION THAT MIMICKED A CUTANEOUS HORN

Abstract

Pyogenic granuloma (PG) is a non-neoplastic vascular tissue growth, which occurs in response to several stimuli. A 15-year-old nonwhite male patient presented with a nonsymptomatic lesion in the lower lip, which was noted for the first time 4 months before. Clinical examination revealed a rigid, brownish, well-delimited, and pediculated nodule, features that led to the clinical diagnosis of cutaneous horn. In an attempt to promote a better wound healing, total removal of the lesional area using the high-power diode laser (808 nm; 1.5 W; continuous mode) was decided. Microscopic examination revealed intense endothelial cells proliferation and new blood vessel formation, besides extensive ulceration areas. Based on these morphologic features, the final diagnosis of PG was established. The patient had very good healing of the incised area on the postsurgical examination and underwent long-term follow-up.
