Background: Pyogenic granulomas are benign vascular proliferations of the skin and mucous membranes. They most typically occur on exposed skin surfaces such as the hands and face but have rarely been reported on the penis.
Case Report: A 22 years-old health man had phimosis before. He found a reddish nodule on his glans 5 years ago, when he circumcised. On examination, a 1 cm reddish mass without surface erosion or bleeding located at the dorsal side of glans. No pain or bleed was noted in these years, even when having sex, but the size increased gradually. Surgical excision performed and glans was repaired with 5-0 prolene suture. The wound recovered well without any shape deformity.
Discussion: Pyogenic granulomas are common, acquired, benign vascular proliferations which occurred on the skin or mucosa. Typically they are solitary, smooth, bright red, rapidly growing papular or polypoid lesions that often ulcerate and bleed. The etiology is not fully understood. It is now widely regarded that pyogenic granulomas have a reactive rather than a neoplastic or infective aetiology. There is also an established link between skin injury and development of pyogenic granulomas.
Only 9 cases of penile pyogenic granulomas had reported in the literature. The relationship between these lesions, phimosis, smegma, and circumcision has been discussed. Included our case, 5 cases were seen in circumcised individuals with prior history of phimosis. Various treatment options for pyogenic granulomas are available. These include surgical excision, electro-cauterization, cryotherapy, laser ablation and micro-embolization.
