[A case of pulmonary actinomycosis that was difficult to distinguish from pulmonary carcinoma].
A 45-year-old male was admitted with chief complaint of hemoptysis. Prior to admission, a tumor in the S3 segment of the right lung had been detected by chest radiography. Despite a detailed examination after admission, no definite diagnosis was made, and right upper lobectomy was performed. Histopathological examination of the surgically resected tissue led to the diagnosis of pulmonary actinomycosis. In Japan, 52 cases of this condition were reported between 1964 and 1991. This paper discusses the epidemiology, diagnosis and diagnostic imaging of the condition, with reference to the literature.
