Pityriasis lichenoides is an uncommon, acquired, papulosquamous disorder that exhibits various clinical presentations, including acute, chronic, and febrile ulceronecrotic Mucha- abermann forms. Pityriasis lichenoides chronica (PLC) is the chronic form of this continuum. Its treatment is challenging for patients and clinicians and some cases are multidrug resistant. Today, this disorder has many treatment choices, including topical corticosteroids, topical calcineurin inhibitors, phototherapy (ultraviolet (UV) A and narrow band UVB), methotrexate, dapsone, cyclosporine and recently etanercept. In our experience, mycophenolate mofetil was effective as a new treatment for pityriasis lichenoides.
