Dermatitis associated with micro®lariae of a nematode of the superfamily Filarioidea was diagnosed in 10 dogs from the western United States. Clinically, lesions were single or multiple papules and plaques with alopecia, scarring, erythema, ulceration, or crusting. Eight dogs had lesional pruritus. Microscopically, there was perivascular, periglandular, to interstitial in¯ammation, with many eosinophils and/or plasma cells, and scarring aecting the dermis and subcutis. Microgranulomas containing micro®laria were seen in six dogs. Micro®lariae were noted in microgranulomas or free in the dermis or subcutis, but not in vessels. In one case, an adult female nematode emerged from a biopsy sample that was placed in physiologic saline. Study of this nematode revealed that it was a ®larioid of the family Onchocercidae; it was identi®ed as Acanthocheilonema sp. (syn: Dipetalonema). Antigen tests of ®ve dogs were negative for Diro®laria immitis. The Knott tests and/or ®lter tests of nine dogs were negative for micro®lariae. An indirect¯uorescence antibody test of one dog was also negative for D. immitis. One dog was not evaluated for micro®lariae.
