Linear lipoatrophy following intra-articular triamcinolone acetonide injection mimicking linear scleroderma

Abstract

A 12-year-old female with oligoarticular juvenile inflammatory arthritis developed an atrophic linear plaque involving the left medial forearm and proximal arm 7 months after intra-articular triamcinolone injection for arthritis. The plaque spontaneously resolved without treatment over approximately one year. It is important to recognize this rare complication of intra-articular steroid injection in order to avoid potential misdiagnosis as linear scleroderma and subsequent immunosuppressive treatment.
