RESUMO
Localized lymphatic sporotrichosis generally develops after the fungus Sporothrix schenckii is traumatically introduced into skin or mucosa by contaminated plant material. An 18-year-old male fisherman was injured by spines of the dorsal fin of a fish on the left third finger. The lesion became ulcerated, edematous and suppurative and did not respond to tetracycline and cephalexin. Fifteen days after the accident, a nodular lymphangitic pattern of swelling was observed. Histopathological findings and an intradermal test were suggestive of sporotrichosis and mycological cultures confirmed the diagnosis. The lesions resolved after oral treatment with potassium iodide. Sporotrichosis is a common subcutaneous mycosis in Brazil, and there is a previous report in the literature of this disease being acquired via trauma involving fish spines.

A case of sporotrichosis transmitted by cat to a veterinarian hospital employees is reported. Inquiry at domiciliary area of the cat's owner revealed two other presumable cases of human sporotrichosis transmitted by cats, and confirmed the diagnosis (by culture of Sporothrix schenckii) of disease in three other domestic cats. Feline sporotrichosis is characterized by ulcerative, cutaneous lesions and systemic dissemination, which invariably cause animal's death. The transmission of sporotrichosis to other animals and humans is enhanced by the great amount of fungus present in cat's lesions.

The authors present the fourth Brazilian case of human Microsporum nanum (M. nanum) infection. A child of nine months old presents cutaneous dorsal lesions compatible with tinea corporis, which appeared one month before. The culture revealed M. nanum. The lesions resolved spontaneously after a month. Epidemiologic investigation in the patient's place of origin identified swine infected by M. nanum, indicating the probable source of the infection.
