Filaria conjunctivae.

A conjunctival neoformation, excised in a 44-year-old healthy Italian man, was histologically diagnosed as Dirofilaria conjunctivae, which is probably Dirofilaria repens, a natural parasite found in dogs of European countries. This parasite rarely infests man in subcutaneous tissues, palpebral, orbital or conjunctival regions. In this case, as in those described by others, the vector remained unknown.
