Extensive Ichthyosiform Sarcoidosis in a Patient With Juvenile Rheumatoid Arthritis

A 23-year-old woman with juvenile rheumatoid arthritis (JRA) developed a generalized ichthyosiform eruption, identified as sarcoidosis, after long-term use of systemic corticosteroids. She experienced progressive hair loss and scalp scaliness over eight years, which worsened despite treatment with topical steroids, emollients, and oral vitamin A. Examination revealed generalized fine white scales and extensive, patchy, nonscarring alopecia. This case highlighted the potential for systemic corticosteroids to contribute to unusual cutaneous manifestations in patients with JRA.
