To report a case of Dirofilaria repens presenting as a subcutaneous tumor of the lower eyelid. Interventional case report. A 29-year-old man of Greek origin without systemic symptoms presented with a 3-week history of a small painless mass localized in the medial part of the lower eyelid. There was no history of a preceding trauma, injury, or visual impairment; however, the patient had recently been on a holiday in Italy. The lesion persisted after systemic antibiotic treatment. Routine blood tests were normal and the efferent tear ducts were patent. Upon surgical intervention a yellowish, pea-sized cyst-like structure was found beneath the orbicularis muscle and removed in toto. Histologic examination revealed the presence of a wormlike structure with the characteristic features of a single adult Dirofilaria repens nematode. Infection with the nematode Dirofilaria repens has to be considered in the differential diagnosis of malignant and benign tumors of subcutaneous periocular tissues in patients who traveled to endemic areas.
