Febrile Ulceronecrotic Mucha- Habermann Disease (FUMHD) is a rare and severe specialized type of Pityriasis Lichenoides Et Varioliformis Acuta (PLEVA). It is characterized by rapid onset of painful necrotic skin lesions and systemic symptoms. The diagnosis of FUMHD is complex and is easily misdiagnosed in the early stages. Despite the increasing number of reports of FUMHD in recent years, it is still uncommon in preschool (3–6 years) children. We here report a 3-year-9-month-old girl of FUMHD from China, cured through combined antibiotics, intravenous immunoglobulin, methotrexate, and prednisone. Besides, a literature review was conducted to synthesize the key findings of preschool FUMHD cases.
