Case Presentation A 73-year-old man was found to have a 15-mm nodular shadow in the left lung on computed tomography and bronchoscopic brush cytology yielded a diagnosis of squamous cell carcinoma. Chest computed tomography showed no evidence of hilar or mediastinal lymphadenopathy. Left lower lobectomy with hilar and mediastinal lymph node dissection was performed. Postoperative histopathological examination revealed squamous cell carcinoma and no lymph node metastasis. On the other hand a lobar bronchial lymph node presented a small lesion showing the dense proliferation of capillary blood vessels with elastic change. Immunohistochemically the lesion was positive for factor VIII and CD34 leading to a diagnosis of primary hemangioma of the lymph node. Conclusion To our knowledge this is the first case reported in the literature of hemangioma in a pulmonary hilar lymph node. Intranodal hemangioma needs to be differentiated from malignant vascular tumors. Background Although lymph nodes frequently display extensive vascularity in association with many different infections and other disease processes the identification of a primary vascular tumor in a lymph node is a rare occurrence 1 . To date only 20 cases have been published as intranodal hemangioma 1-6 . As rightfully stated by Almagro et al. these should be reported because of their unclear natural significance 3 . We present a case of a primary intranodal capillary cavernous hemangioma and the first case documented to occur within a pulmonary hilar lymph node. Case Presentation The patient was a 73-year-old man .
