title: [Nocardia otitidiscaviarum, cutaneous infection in a patient receiving long-term corticosteroid treatment].
abstract: A 62-year-old man, under long-term corticosteroid therapy for pigeon breeder's disease, was admitted to endocrinology disease department for cutaneous abscess on back, limbs and scalp. Culture of various bacteriological samples (cutaneous abscess, blood culture) isolated Nocardia otitidiscaviarum. The patient was treated by trimethoprime-sulfametoxazole during several weeks with abscess disappearance. Our laboratory quickly identificatied a bacteria belonging to the Nocardia genus, with simple technique, later confirmed by a specialized laboratory (Pr. Boiron Claude Bernard University Lyon I) with identification of Nocardia otitidiscaviarum. The proof of pulmonary nocardiosis could not be established despite the existente of several risk factors. Prognosis is poor for immunocompromised patients, but the secondary cutaneous dissemination phase presented a favourable evolution under antibiotic therapy.
