title: Allergic granulomatosis (Churg-Strauss) associated with cutaneous manifestations: report of two cases.
abstract: Allergic granulomatosis (Churg-Strauss) is sometimes associated with cutaneous manifestations. Biopsies of these manifestations are characteristic enough to allow for the diagnosis of this disease through histological examination. Case 1 involved a 34-year-old man who developed a low-grade fever, blood eosinophilia, paralysis of the right oculomotor nerve, and a polymorphic eruption. In addition, he suffered from preceding asthma and paresthesia of the legs and eventually developed heart failure. The histological examination of a biopsy taken from a hemorrhagic bulla showed a dense perivascular infiltration of eosinophils in the upper dermis and basophilic degeneration of collagen fibers. Case 2 involved a 41-year-old man who was afflicted with urticarial erythemas, livedoid erythemas, preceding asthma, and blood eosinophilia. During the course of his illness, he also developed bilateral peroneal nerve paralysis and two small erythemato-bullous lesions. The histological examination of a urticarial lesion revealed an abundant eosinophil perivascular infiltration; examination of a nodule revealed basophilic degeneration with a granulomatous reaction. Clinical and laboratory studies strongly suggested the diagnosis of allergic granulomatosis in both of these cases. The diagnosis was also supported by a histological examination of the skin lesions.
