Mortality risk factors in febrile ulceronecrotic Mucha- Habermann disease: A systematic review of therapeutic outcomes and complications.

Febrile Ulceronecrotic Mucha- Habermann Disease (FUMHD) is a variant of Pityriasis Lichenoides Et Varioliformis Acuta (PLEVA). Although rare, the condition may progress to involve serious complications and even lead to fatal outcomes if diagnosis and appropriate treatment is delayed. A PubMed search following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRIMSA) guidelines was performed to find cases of FUMHD from the earliest records to October 2021.
