Febrile ulceronecrotic Mucha-Habermann disease in adult patient successfully treated with systemic corticosteroid.

The Febrile Ulceronecrotic Mucha-Habermann (FUMHD) disease is a rare variant of pityriasis lichenoides et varioliformis acuta (PLEVA). Its etiology still remains unknown and it is characterized by a sudden onset of ulceronecrotic skin lesions associated with systemic symptoms. It is reported here the case of a male patient with a sudden and acute evolution of macules and papules, ulceronecrotic and vesicle-bullous lesions associated with systemic symptoms. The patient was treated with prednisone 0.5 mg/kg/day with a dramatic response. The FUMHD is a severe variant of PLEVA and its diagnosis is clinical and histopathological. Many treatments such as methotrexate, corticosteroids and PUVA have been described. However, none of them has been settled.
