Abstract
We experienced three cases of Paragonimiasis including one resected cse. All patients were male. A 55-year-old man was admitted to our hospital on March, 1st, 1996 because of hemo-sputum. Chest X-P film revealed a nodular shadow and cavity in the right upper lung field. He was suspected of pulmonary tuberculosis, so received anti-TB drugs for 6 months. 12 months later, the nodular shadow increased in size, causing stenosis of bronchus on chest computed tomography. The pre-operative findings did not lead to a definitive diagnosis, and lung cancer could not be excluded. He underwent right upper lobectomy on March, 18th, 1997. Intra-operative pathological diagnosis was Paragonimiasis. He was treated with praziquantel for 2 days at a daily dosage of 40 mg/kg.
A 45-year-old man presented with hemosputum, pleural effusion and nodular shadow on chest X-P. Pleuritis carcinomatosa could not be excluded.
A 13-year-old male suffered from abdominal pain, high-grade fever and leukocytosis (eosinophilia 13 %). In both cases, eggs of Paragonimiasis were found in their sputa. They were treated with oral administration of bithionol (40 mg/kg every 15 days). After completion of the therapy, their clinical signs disappeared.
All patients had ingested uncooked fresh wild boars captured by them-selves. In Japan, Paragonimiasis is recently rarely reported, but it is important to have this disease in mind when a patient has a history of eating wild boar meat.
