He presented with a 5-month history of polyarticular arthritis, skin thickening and hypopigmented skin lesions. After 2\u2009months of treatment with methotrexate, he reported minimal improvement in joint pain, swelling and skin thickening, followed by worsening after self-cessation of treatment due to varicella zoster infection.
