Pulmonary dirofilariasis mimicking lung cancer.

We describe the case of a 30-year-old asymptomatic farmer who underwent a pulmonary segmentectomy due to the casual finding of a pulmonary nodule in preoperative chest radiography. As bronchoscopic samples rule out mycobacterium infection and malignancy, surgery could have been avoided with the use of serological tests and radiographic follow-up based on epidemiology of dirofilariasis in our country.
