• Six cases of subcutaneous dirofilariasis are reported, three located in the eyelid, two in the periorbital region, and one in the subconjunctival tissues. Three patients lived in Florida, two in North Carolina, and one in Mississippi. All patients were adults, ranging from 27 to 69 years of age (median age was 58 years). Most patients experienced an inflamed painful nodule that contained portions of a nematode. The morphologic features for identification of the worm as belonging to the genus Dirofilaria are outlined.
