Cutaneous lesions are rarely inaugural in Churg and Strauss syndrome. We report the case of a patient in whom recurrent papular lesions of the penis revealed a Churg-Strauss granulomatous angeitis.A 54 year-old man consulted for recurrent non-infiltrated and painless erythematous papules of the penis over the past 4 years. His past history revealed severe asthma, which had appeared at the same time, nasal polyposis and chronic sinusitis. Other than the genital organs, the clinical examination was normal. Histological exploration of a cutaneous biopsy of the penis showed a necrotic granulomatous vasculitis. The usual biological examinations were normal. Research for proteinuria, hematuria and measurement of polynuclear anticytoplasm antibodies were negative. Pulmonary X-ray revealed a bilateral interstitial syndrome with micronodules. The broncho-alveolar wash revealed moderate granulocyte alveolitis with numerous eosinophilic polynuclears. The electromyogram showed a reduction in the sensitive potential of the nerves explored in the 4 limbs. Churg-Strauss granulomatous angeitis was diagnosed. Treatment with 0.8 mg/kg/day of prednisone was initiated. The cutaneous lesions disappeared rapidly. Since three months later there had been no relapse, corticosteroid therapy was slowly and progressively reduced. Nine months later, the patient exhibited new papular lesions of the glans penis and progressive relapse of asthma. Treatment with cyclophosphamide (Endoxan(R)) combined with systemic corticosteroids was initiated.In view of the concomitance of necrotic granulomatous vasculitis in the cutaneous biopsies, severe, recent corticosteroid-dependent asthma, eosinophil-rich pulmonary infiltrate, allergic rhinitis, chronic sinusitis and the onset of a neuropathy, the diagnosis of Churg-Strauss syndrome was retained. The absence of hypereosinophilia in the blood during diagnosis can be explained by the oral corticosteroid therapy at low doses because of the asthma and sinusitis. However, hypereosinophil blood levels had been reported in several prior hemograms. Damage to the genital organ is exceptional during Churg-Strauss syndrome and is usually of granulomatous prostatitis form. Only one other case has been reported. Our observation is original in that it was isolated to the genital skin, which led to the diagnosis of Churg and Strauss granulomatous angeitis with systemic involvement. |
