Dirofilarial infection presenting as a facial mass: Case report of an emerging zoonosis.

摘要

Dirofilariasis is a parasitic infection caused by nematodes. Human infection remains rare but is increasing in scope, particularly in endemic areas. Dirofilariasis typically presents as a subcutaneous mass or with pulmonary nodules. Here, we present the case of a 73-year-old woman whose asymptomatic facial mass was caused by dirofilarial infection. The pathophysiology, diagnosis, and treatment of dirofilariasis of the head and neck will be discussed. In endemic areas, dirofilariasis must be considered in the differential diagnosis of facial masses.
