Fat atrophy at the site of a subdermal contraceptive implant.

©FFPRHC J Fam Plann Reprod Health Care 2007: 33(2) Background Progestogen-only implantable contraceptives are an increasingly popular method of contraception used by women worldwide. The implants are inserted subdermally into the arm and slowly release synthetic progesterone into the systemic circulation to prevent pregnancy. Over the years, in response to well-publicised side effect profiles, there has been an evolution in the composition and insertion methodology of these implants. Prior to their insertion, patients should be counselled regarding associated risks and side effects at both local and systemic levels. Whilst systemic side effects have been extensively researched, we discuss a case of fat atrophy located at the site of an implant, a hitherto unpublicised local side effect.
