[Bullous erythema nodosum leprosum. A case report in French Guiana].

BACKGROUND: Polar and borderline lepromatosis leprosy can be complicated by type 2 reactional states, including erythema nodosum leprosum.

CASE REPORT: A 36-year-old man was treated for lepromatous leprosum. He consulted for recurrent erythema nodosum leprosum. Certain nodular lesions were bullous. Histopathology demonstrated major dermal edema causing bullous blisters. Treatment with thalidomide led to rapid regression.

DISCUSSION: The bullous form of erythema nodosum leprosum is rarely described in the literature. It raises the diffential diagnosis with other bullous dermatoses, particularly Sweet's syndrome.
