A 35-year-old man was admitted to a hospital in the south of Italy because of a periocular nodule and subpalpebral edema. The patient reported having been stayed in Tanzania five months before. Hematologic parameters were within the normality range, the Acanthocheilonema viteae ELISA did not detect significant levels of antifilarial IgG, and no further symptoms were described. The surgical inspection of the nodule led to the isolation of two filarioid parasites, identified as Dirofilaria repens by scanning electron microscope (SEM), and then by molecular assays. Knott's test did not reveal microfilaremia, whereas loop-mediated isothermal amplification andPCRdetected D. repens DNA. The patient was treated with doxycycline, and he was found no more positive at the follow-up.

Abstract
A 35-year-old man was admitted to a hospital in the south of Italy because of a periocular nodule and subpalpebral edema. The patient reported having been stayed in Tanzania five months before. Hematologic parameters were within the normality range, the Acanthocheilonema viteae ELISA did not detect significant levels of antifilarial IgG, and no further symptoms were described. The surgical inspection of the nodule led to the isolation of two filarioid parasites, identified as Dirofilaria repens by scanning electron microscope (SEM), and then by molecular assays. Knott's test did not reveal microfilaremia, whereas loop-mediated isothermal amplification andPCRdetected D. repens DNA. The patient was treated with doxycycline, and he was found no more positive at the follow-up.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
