Introduction:
Tocilizumab (TCZ), a recombinant humanized antihuman monoclonal antibody targeting interleukin-6 (IL-6) signaling, is often utilized in the management of autoimmune disease. Few reports have demonstrated hair growth changes in patients on TCZ.
Case Presentation:
Herein, we review the literature and report a 21-year-old woman with progressive alopecia areata (AA) presenting with AA improvement while on TCZ for concomitant posterior uveitis.
Discussion:
Our case demonstrates the potential ability of TCZ to disrupt IL-6 signaling involved in AA, leading to hair loss and regrowth.
