Conteúdo: 	A peculiar chronic dermatitis of the teats was prevalent in 25% of grazing cows over 16
months old in the Nansei (southwest) Islands belonging to Okinawa Prefecture. The con-
dition was characterized by a palule-like swelling with pain, an ulcerating core,  hermorrha-
ge, the disappearance of melanin pigment, hyperkeratosis, and the formation of craks and
crusts. Loss of the affected teat has ocasionally been observed, particularly among cows
suckling calves. Nematodes identified as Stephanofilaria okinawaensis Ueno and Chiba-
na, 1977 were collected from small pieces of affected teats obtained by biopsy. The para-
sites were frequently found in the subepidermal layer of affected teats. The lesions predo-
monantly contained eosinophils but monocuclear cell infiltration was also present. In the
enzootic area, chronic dermatitis of cattle caused by the same parasite was more preva-
lent on the muzzle than on the teat. Its incidence on the muzzle was 66% among animals
over 5 months old. Dermatitis of the teat was observed only amongst cattle with lesions on the muzzle.
