Febrile ulceronecrotic Mucha-Habermann disease: a case with systemic symptoms managed with subcutaneous methotrexate.

Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare, idiopathic, acquired dermatosis that can affect all ages and ethnic groups. We present a 10-year-old patient with FUMHD associated with arthritis and chronic fatigue, managed with methotrexate. Through our literature review, we also explore treatment protocols for a disease for which internationally standardized management is yet to be formulated.
