We describe 5 cases of anti-tumor necrosis factor-alpha (anti-TNF-α) induced psoriasiform eruptions with severe scalp involvement inducing inflammatory alopecia and review the literature on this subject. All our 5 patients were provided topical therapy, with good results in only 1 case. The remaining 4 were provided systemic therapy (methotrexate ± cyclosporine): 3 concomitantly suspended the anti-TNF-α treatment (2 are currently clear/almost clear but 1 has so far only observed mild improvement) and 1 switched anti-TNF-α (recurrent flare-ups of the disease continue). So far, no patient has developed scarring alopecia. To our knowledge, a total of 15 cases of anti-TNF-α induced psoriatic alopecia have been described. Anti-TNF-α was discontinued in 9 of the 15 patients and systemic therapy was provided to 9 of the 15 patients. Nonetheless, 2 patients developed scarring alopecia. We conclude that in anti-TNF-α induced psoriasiform eruptions some patients may respond to topical treatment, however in cases of severe scalp involvement anti-TNF-α suspension and systemic treatment should be considered in order to avoid scarring alopecia.
