Foreign body injection into the penile shaft ,in the mistaken belief that it could increase the size, is not uncommon among Thai males. Paraffin, oil, and other materials had been injected into the penile skin and predictably followed by a lot of complications. Foreign body granuloma, disfigurement, chronic and unhealed ulcer ,painful erection, and the inability to achieve sexual activities are those following complications. In the severe cases, even though the complete resection of the skin and all of the infiltrated tissue was meticulously performed ,some foreign bodies had to be left since they had incorporated into either the corpus cavernosum or corpus spongiosum. Durable resurfacing skin can’t be perfectly achieved by skin grafting in these situations. Between 1996 and 2002, 31 patients with penile paraffinoma have been treated using bilateral scrotal flaps. Both functional and cosmetic goals without any major complications were achieved in all of the patients.
