[Pigmentation change, muscle wasting, and tendon rupture after corticosteroid injection in the Congo].

Unlike complications of systemic corticosteroid therapy that have been extensively described, complications of locoregional corticosteroid injection are not well documented. The purpose of this report is to describe a case involving iatrogenic injury due to local corticosteroid therapy in a 17-year-old woman. Following injection of triamicinolone into the wrist, the patient developed pigmentation change, muscle wasting, and tendon rupture. Injection was performed by a nurse, thus indicating the need for training before delegating this procedure in areas with limited resources.
