A Case of Molluscum Contagiosum in an Adult Patient with Rheumatoid Arthritis, Following Combination Therapy with Adalimumab, Methotrexate and Prednisolone

A 46-years old female was referred from the rheumatology department with diffuse skin lesions. She had been diagnosed with rheumatoid arthritis in 2006 and initially underwent treatment with a combined regimen of methotrexate (MTX, 12.5 mg per week), prednisolone (2.5 mg per day) and leflunomide (10 mg per day). Dueto the poor response, leflunomide was substituted to adalimumab (40 mg every other week) in September 2014 after negative screening for viral hepatitis and tuberculosis. 6 months into the combined therapy of adalimumab, prednisolone and methotrexate, the patient developed multiple, tiny erythematous to skin-colored papules and referred to the department of dermatology.
