Debilitating silicone granuloma of the penis and scrotum.

The restoration and improvement of body contour have intrigued surgeons for over 100 years, generating much interest in the subcutaneous/intradermal injection of highly viscous fluids. The local complications of liquid silicone injection have been well documented over the past 30 years. Although Dow-Corning has not made medical-grade liquid silicone available for use in humans without an approved research application since 1966, practitioners, both licensed and unlicensed, have administered these injections worldwide for a variety of indications throughout the body. There is little or no information concerning the adulteration of these injectates. To date, there have been four case reports of penile injections--the indications being evenly split between the treatment of impotence/sexual inadequacy and augmentation. The most recent description was published in 1982. We present a case of debilitating silicone granuloma of the penis and scrotum secondary to large-volume injections into the corpora cavernosae and penile soft tissues administered in Belgium 14 years prior to presentation. The development of a silicone foreign body reaction, massive edema, and subsequent impotence lends itself to a clinical diagnosis and aggressive treatment with wide local excision and appropriate soft-tissue coverage. The metabolic fate of silicone in vivo remains inadequately characterized and a fertile area for research as new methods involving nuclear magnetic resonance spectroscopy have been devised to identify silicone and highly coordinated silicone complexes.
