Pyogenic granuloma (PG) is a reactive local benign vascular lesion, where connective tissue fibrovascular proliferation occurs. The most common etiology of PG is chronic, low-level irritation. PG affects females mainly. The purpose of this paper is to report a giant pyogenic granuloma caused by an acute trauma in the upper lip of an 11-year-old boy. The initial clinical diagnosis suggested PG, which was confirmed after an excisional biopsy and a microscopic exam. Oral lesions of large proportions in children can cause functional, esthetic, and behavioral issues, and should be promptly investigated.
