This patient unfortunately caused severe trauma to his penis requiring surgical intervention. Photographs of the traumatic injuries are presented. Background Pearling also known as genital beading is the practice of permanently inserting small beads made of various materials beneath the skin of the genitals 1 . As well as being an aesthetic practice this is usually intended to enhance the pleasure of partners during sexual intercourse by increasing physical stimulation. It is most commonly done on the dorsal surface of the shaft of the penis where small superficial incisions are made and beads are placed under the skin surface. Most implants are made of small inert metal beads stainless steel titanium or plastic beads nylon silicone . This form of body modification is still practiced in various world cultures. Historically the Yakuza of Japan an organized crime syndicate is the most well known for pearling. Each pearl supposedly symbolizes each year that was spent in prison. Interestingly pearling has become more commonplace in the United States especially in the US prison system. Case presentation A 19-year-old male inmate presented to our Emergency Department ED after attempting to purposefully cut the dorsal surface of his penis with a brand-new razor blade for self-performed pearling. He made two horizontal incisions on the shaft one proximal and close to the base of the penis and one distal near the glans penis. This was performed approximately 6-7 h prior to arrival at the ED. The patient alerted the prison staff to request medical .
