A 74-year-old male cigarette smoker presented with hemoptysis and a right upper lobe infiltrate. Fiberoptic bronchoscopy revealed a small (1 x 2 mm) benign-appearing lesion in the right upper lobe bronchus which, on biopsy, was a submucosal capillary hemangioma. This is an exceedingly rare tumor and, to our knowledge, hemoptysis from these lesions in the proximal bronchi has not been previously reported.
一名74岁男性吸烟者因咯血和右上叶浸润就诊。纤维支气管镜检查显示右上叶支气管内有一个小的（1×2毫米）外观良性的病变，活检显示为黏膜下毛细血管瘤。这是一种极其罕见的肿瘤，据我们所知，此前尚未有关于近端支气管这些病变引起咯血的报道。
