Living with Febrile ulceronecrotic Mucha-Habermann disease

A rare, severe skin condition with sudden, large, painful skin ulcers and fever, more often in children.

Understanding Febrile ulceronecrotic Mucha-Habermann disease

Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare and severe form of a skin condition called PLEVA.

PLEVA causes skin lesions that break down into open sores and then form a red-brown crust. FUMHD often starts as PLEVA but quickly progresses to large, destructive ulcers. Fever and painful skin loss can occur, and ulcers can become infected. It is diagnosed with a skin biopsy. It occurs more often in children and in males.

GARD doesn't list a separate symptom list. Its summary describes:

  • Skin lesions that become open sores
  • Red-brown crusts
  • Large, destructive skin ulcers

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
