Human pulmonary dirofilariasis has been documented from many parts of the world, but not in Korea so far. We experienced a patient of pulmonary dirofilariasis who had visited a local clinic because of chest pain for 1 month. On chest radiograph, a coin lesion of 2 cm diameter and enlargement of the mediastinal lymph node were shown. An exploratory lung resection was done. Pathologically the lesion was a pulmonary dirofilariasis complicated with necrotic pneumonia, fibrosis, and infarction. At the center of the lesion, degenerated nematode sections with multilayered cuticle, thick musculature, and bilateral internal ridges on each side were found, which was identified to be Dirofilaria immitis. This is the first report of human pulmonary dirofilariasis in Korea.

A 27-year-old man presented at the emergency room with hemoptysis. His blood pressure was 180/100 mm Hg, and he had no history of hypertension. Chest radiographs showed bilateral infiltration, suggestive of alveolar hemorrhage. His laboratory data were consistent with acute kidney injury. His serum creatinine level increased abruptly; therefore, renal biopsy was performed. Steroid pulse therapy was administered because of a strong suspicion of immune-mediated pulmonary renal syndrome. Renal biopsy showed proliferative endarteritis, fibrinoid necrosis, and intraluminal thrombi in the vessels without crescent formation or necrotizing lesions. Steroid pulse therapy rapidly tapered and stopped. His serum creatinine level gradually decreased with strict blood pressure control. Ten months after discharge, his blood pressure was approximately 120/80 mm Hg with a serum creatinine level of 1.98 mg/dL. Pulmonary renal syndrome is generally caused by an immune-mediated mechanism. However, malignant hypertension accompanying renal insufficiency and heart dysfunction causing end-organ damage can create a pulmonary hemorrhage, similar to pulmonary renal syndrome caused by an immune-mediated mechanism. The present case shows that hypertension, a common disease, can possibly cause pulmonary renal syndrome, a rare condition.

BACKGROUND: The diffuse infiltrative lung disease requires surgical lung biopsy for its final diagnosis. We evaluated the effect of surgical lung biopsy for final diagnosis of duffuse interstitial lung disease and compared video assisted thoracoscopic lung biopsy (TLB) with open lung biopsy (OLB). MATERIAL AND METHOD: We evaluated the patients who underwent surgical lung biopsy from March 2000 from December 2005, retrospectively. We divide to two groups (OLB and TLB group) and compared them. RESULT: There were 36 patients and cough was the most common pre- operative symptom. Surgery time, anesthetic time, hospital stay, duration of chest tube indwelling, specimen volume and the rate of post-operative complication were not significantly different between two groups. Histologic diagnosis was confirmed in all cases. There was one post-operative death who had suffered from respiratory failure since pre-operative period. CONCLUSION: Surgical lung biopsy is effective method in final diagnosis for diffuse infiltrative lung disease. Video assisted thoracoscopic lung biopsy is lesser invasive method than open lung biopsy and provide similar results, so it is basic diagnostic method of surgical lung biopsy.
