[Case of broncholithiasis lithoptysis occurring spontaneously after repeated pneumonia].

An abnormal chest shadow was pointed out in a 56-year-old woman in a health check in 2001. She had pulmonary tuberculosis at age 11. Because of repeated fever for the previous 2 years, she visited our hospital in 2003 and right upper lobe pneumonia was detected with a calcified nodule that completely obstructed the right upper lobe bronchus on CT.

[A case of atypical pulmonary carcinoid accompanying skin metastasis].

A 73-year-old woman underwent cranial surgery in 1999 after receiving a diagnosis of suspected malignant meningioma. She began complaining of headache 2 years postoperatively, and around the same time, she noticed a painful skin tumor. She was then transferred to our hospital for further evaluation.

[An intra-pulmonary lymphnode resembling typical pulmonary primary adenocarcinoma on high-resolution computed tomographic (HR-CT) chest images].

A 40-year-old man was admitted to our hospital for further evaluation of a pulmonary nodule in chest radiographs. The 8-mm nodular lesion was located in the right anterior basal lobe on a plain chest radiograph, and showed 1) spiculation, 2) pleural indentation and 3) a converging vessel formation in high-resolution computed tomography of the chest. The radiographic findings were highly suggestive of primary pulmonary adenocarcinoma and the patient underwent video-assisted thoracoscopic surgery (VATS) to obtain a precise diagnosis.
