A linear forehead lesion caused by intralesional injection of triamcinolone acetonide and treated with hyaluronic acid filler: case report

Intralesional steroid injection is a treatment method frequently used to resolve a large number of orthopaedic, rheumatological, dermatological, neurological disorders. Although this treatment is very effective, it is not without possible side effects, both systemic and local, among which we can mention pain, bleeding, ulceration, atrophy, pigmentary changes, calcification, secondary infections, formation of granulomas, allergic reactions and, in very rare cases, the development of linear atrophy and hypopigmentation. Here, we present a case of frontal linear skin atrophy after intralesional steroid injection for the treatment of alopecia areata (AA) in a 29 year-old patient, successfully treated with a hyaluronic acid filler.
