    Chronic parasitosis due to nematode worms (filariae) in tissue are very common in tropical ecosystems; their larvae (microfilariae) have been isolated in lymph vessels, skin, and blood. The case reported here is of a Nigerian patient suffering severe renal failure and admitted owing to the presence of a right submandibular gland abscess. In the FNAP, the presence of a Mansonella perstans microfilaria was identified. Post-surgery examination of pathology samples from the gland reported an acute inflammatory infiltrate including abundant eosinophils and microfilariae. There are some reports in the literature of haematic or lymphatic microfilariae, especially in epithelial or glandular tissues, and, as in this case, in inflammatory or malignant conditions. Both ivermectin and mebendazol are used for treatment; the scant pathogenicity of the genus Mansonella should, however, lead to an individualized decision.
