title: Febrile ulceronecrotic Mucha-Habermann's disease.
abstract: Febrile ulceronecrotic Mucha-Habermann's disease (FUMH) was first described by Degos in 1966. In the literature, nine cases of FUMH have been reported in both children and adults. We report a 16-year-old boy with the febrile ulceronecrotic type. A review of the nine cases in the literature showed acute necrotic lesions, as well as rare complications such as fever, superinfected lesions and viral infection which are not as common in pityriasis lichenoides et varioliformis acuta. There is no definitive treatment, but systemic corticosteroid, methotrexate, antibiotics (tetracycline, erythromycin), aciclovir, and 4,4-diaminodiphenyl sulfone (DDS) have been frequently used. The most common histologic feature is mononuclear perivascular infiltrates consisting of T lymphocytes. The etiology is not known, but a hypersensitivity reaction, possibly to an infectious agent, is suggested.
