Methotrexate-Induced Accelerated Nodulosis: A Case Series

Methotrexate-induced nodulosis, also known as methotrexate-induced accelerated nodulosis (MIAN), is a rare side effect of methotrexate therapy. Methotrexate (MTX) is commonly used to treat various autoimmune diseases, such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease. In this case series, we present patients with MIAN, discussing their clinical features, diagnostic approaches, and management strategies. We aim to increase recognition of this rare side effect of MTX therapy, facilitate early diagnosis, and improve clinical management, thus minimising the burden of this debilitating complication on affected individuals.
