[Cutaneous alternariosis and its diagnosis in an inmunocompromised patient].

In this paper, a cutaneous alternariosis is described. This is a strange opportunist infection with less than 100 cases. The patient was not VIH although inmunocompromised due to several factors: Malabsorption Syndrome, megaloblastic anemia secondary to gastrectomy and distal pancreatomy with gastrodigiunostomia due to gastric adenocarcinoma four years ago; splenectomied in the same operation, long treatment with hydantoin, and corticosteroids. The patient was managed in the internal medicine unit due to a problematic respiratory infection with cardiac rhythm disorder and progressive debility in lower limbs, together with cutaneous lesions in which "alternaria sp" was isolated by culture. After beginning treatment with oral itraconazole, his evolution was excellent. The main interest consists in the rareness and the original presentation of the cutaneous alternariosis in this case.
