淋巴血管瘤(hemolymphangioma)是起源于间胚叶组织的一类良性肿瘤,瘤内既含有血管(多以静脉为主),又含有淋巴管[1]。病因上分为原发性和继发性[2]。原发性淋巴血管瘤是脉管系统先天发育异常,胚胎塑形不良的血管组织与大循环之间的静脉淋巴管通路闭塞后,导致肿瘤形成。继发性淋巴血管瘤通常由外伤或手术引起淋巴管损伤。该肿瘤好发头颈部,如位于疏松结缔组织体积较大者 Hemolymphangioma is a type of benign tumor that originates from the mesodermal tissue. The tumor contains both blood vessels (mainly venous) and lymphatic vessels [1]. Etiology is divided into primary and secondary [2]. Primary lymphatic hemangioma is a congenital dysplasia of the vasculature that leads to tumor formation after occlusion of the venous lymphatic vessels between the vascular tissue with poorly shaped embryonic circulation and the large circulation. Secondary lymphatic hemangiomas usually cause lymphangiogenesis by trauma or surgery. The tumor is good at the head and neck, as in loose connective tissue larger volume
