[Human dirofilariasis: extraction of the living nematode from the upper lip]

Calabar swellings appearing on the head during 2 months in a 53 year old man, living in Casale Monferrato (Piedmont), were followed by the formation of a nodule 2 x 1 cm wide, in the upper lip. A mobile filiform, 12 cm long, nematode was recovered from the excised nodule. It was diagnosed as Dirofilaria repens. The region where the case occurred, is to be considered as one of the most affected areas by this parasitic zoonosis in Europe.
