A solitary pulmonary capillary hemangioma is a benign tumor that develops simply from capillary endothelial cell proliferation, and affected patients generally have a good prognosis. However, chest CT findings occasionally reveal this tumor as a small nodule with ground-glass opacity, making it difficult to distinguish from well-differentiated lung adenocarcinoma. We treated a 42-year-old woman in whom chest CT showed a small nodule with ground-glass opacity (13 mm) in the right S9 segment. Suspected to be well-differentiated lung cancer, we performed a right basal segmentectomy using a total thoracoscopic surgical procedure for diagnosis and treatment. The histopathological diagnosis was solitary pulmonary capillary hemangioma. There have been no signs of recurrence on follow-up examinations following the operation.
