A 76-year-old woman admitted to our hospital with abnormal shadow on chest X-ray. Computed tomography demonstrated the 2 x 2 cm of round, well defined tumor on right S6 segment which was suspected to be a malignant tumor. Partial resection was performed with video-assisted thoracotomy (VATS) and histological examination of quickly frozen specimen showed no malignancy. Then, histological examination of formalin fixed specimen showed dirofilariasis. It has been reported 97 cases of dirofilariasis in Japan so far. Although X-ray or biochemical and immunological examination of serum help to diagnose dirofilariasis, difinite diagnosis can be done only by histological evidence of resected specimen. Because of the difficulty for denial the malignant tumor, surgical treatment should be required.
