[A case of dirofilariasis in the town of Magnitogorsk of the Cheliabinsk region].

A local case of dirofilariasis was first reported in a 70-year-old female in Magnitogorsk, Chelyabinsk Region, in November 2002. The primary diagnosis is atheroma of the skin of the forehead. A round mass having a smooth surface and slightly solid gray-whitish walls was surgically excised, which yielded a mobile rolled nematode measuring 7 cm in length and 0.8 mm in width. The parasitological diagnosis is an immature Dirofilaria repense female. It has been found that the female has neither dogs nor cats in her flat and she had not been left Mangitogorsk for approximately 18 years. A histological examination of the fibrotic capsule around the parasite revealed inflammation in the inner layer of the capsule, which was regarded as proliferative and having no signs of a granulomatous process. Fragments of cuticles of a round helminth having a well-defined alimentary tube was found. To encode the case, the authors have used Category B74.8 "Other types of filarisis (dirofilariasis)" of the first class, ICD-10.
