Tumoral pulmonary mass secondary to Schistosoma mansoni infection resembling neoplasia: case report.

Patients with chronic Schistosoma mansoni infection may feature a range of pulmonary symptoms and radiological findings. Eggs, and rarely adult worms, may passively enter the pulmonary circulation, usually via the portal system, where they may cause pulmonary inflammation, fibrosis, hypertension and cor pulmonale. A 25-year-old patient who lived in a schistosomiasis endemic area with a pulmonary mass suggestive of malignancy underwent exploratory thoracotomy.
