Cardiac tumors are significantly rare, with pericardial lymphangiohemangioma amongst the rarest cardiac tumor types, with very few reported cases in the literature. Clinically, lymphangiohemangiomas are generally deemed unresectable due to their proximity to the myocardium and the uncertainty of the outcomes following subtotal resection. Herein, we report a case of a 40-year-old man diagnosed with a pericardial mass, dull thoracodorsal pain, and over a 10-years history of palpitation. Notably, the pericardial mass in the present case was found extended within the myocardium. Thus, a maximal safe resection was deemed preferable to a total resection. The surgically resected specimen showed pathological characteristics of a lymphangiohemangioma. After surgical resection of the lymphangiohemangioma, the patient was free of any tumor-related symptoms. Also, there was no evident tumor progression after a 4-year post-operative follow-up. To the best of our knowledge, the present case study is the first in the literature to report on a long-term post-operative outcome following subtotal resection of a pericardial lymphangiohemangioma.
心脏肿瘤极为罕见，心包淋巴管瘤是最罕见的心脏肿瘤类型之一，文献中报道的病例极少。临床上，由于淋巴管瘤靠近心肌且次全切除术后预后不确定，通常认为其不可切除。在此，我们报告一例40岁男性患者，诊断为心包肿块、胸背部钝痛，并有10余年心悸病史。值得注意的是，本病例的心包肿块被发现延伸至心肌内。因此，最大安全切除被认为优于全切除。手术切除的标本显示出淋巴管瘤的病理特征。淋巴管瘤手术切除后，患者无任何肿瘤相关症状。此外，术后4年随访未发现明显肿瘤进展。据我们所知，本病例研究是文献中首例报道心包淋巴管瘤次全切除术后长期预后的病例。
