To the Editor: Capillary hemangioma is rarely observed in the lung, although the lung contains many capillaries. Solitary pulmonary capillary hemangioma (SPCH) is a recently recognized rare benign and proliferative capillary lesion. It shows no symptoms, and is displayed as a ground-glass nodule (GGN) (pure GGN or part-solid nodule) on computed tomography (CT). SPCH is macroscopically observed as a brownish area, which resembles focal congestion or hematoma. We here present a case of SPCH and its true gross appearance after drainage of the blood from the specimen. A 9mm part-solid nodule with the air bronchogram sign was detected in the left lobe of the lower lung in an asymptomatic 46-year-old man on chest CT during cancer screening (Fig. 1a). Five months later, a follow-up chest CT was performed; however, there were almost no changes in the size and density of the nodule. Therefore, lung carcinoma of the peripheral type was suspected. Surgery was subsequently performed. Because the lesion was impalpable intraoperatively, lobectomy was performed instead of partial
