概要

A 71-year-old man was noted to have a nodular opacity in S8 of the right lung. Thirteen months later, the chest CT showed a lesion "gloved finger shape" with focal calcification, and a small nodular opacity appeared in right S7. A right lower lobectomy was performed under video-assisted thoracic surgery. The tumor filled the S8 bronchus, with invasion into the pulmonary parenchyma and S7 metastasis. Mitotic figures were seen in 5 of 10 high power fields. Positive staining for chromogranin A and synaptophysin led to the diagnosis of atypical carcinoid. The patient has been disease-free without treatment for 9 months.
