Dirofilariasis in humans presenting as a subcutaneous nodule

Abstract

Human dirofilariasis is an uncommon zoonotic roundworm infection caused by worms belonging to dirofilaria species transmitted by zoo -anthropophilic blood sucking insects which is known to manifest as ocular infection or as a subcutaneous nodule usually in the upper part of the body. We present a case report of subcutaneous dirofilariasis in the left temporal region besides the eye brow in a 65yr old female, clinically diagnosed as epidermal cyst. Gross and histopathological evaluation revealed the presence of an adult worm with granulomatous inflammatory reaction.
