Lymphangiectasia is a congenital or acquired disorder characterized by abnormal, dilated lymphatics with a variable age of presentation. We describe a case of lymphangiectasia with intestinal and pulmonary involvement in an adolescent female, who presented with many of the classic features including chylous pleural effusions, lymphopenia, hypogammaglobinemia, and a protein-losing enteropathy. She also presented with recurrent lower gastrointestinal bleeding, which is infrequently described. The patient did not improve with bowel rest and a low-fat medium-chain triglyceride diet and had little improvement with octreotide acetate therapy. However, she had a clinical response to antiplasmin therapy, trans-4-aminothylcyclohexamine carboxylic acid (tranexamic acid) in terms of serum albumin and gastrointestinal bleeding. She continues to have exacerbations of her condition, as well as persistent lymphopenia and chronic pleural effusions.
淋巴管扩张症是一种先天性或后天性疾病,其特征为淋巴管异常扩张,发病年龄不一。我们报告一例青春期女性淋巴管扩张症合并肠道和肺部受累的病例,该患者具有许多典型特征,包括乳糜性胸腔积液、淋巴细胞减少、低丙种球蛋白血症和蛋白丢失性肠病。她还出现了反复的下消化道出血,这一情况鲜有报道。该患者经肠道休息和低脂中链甘油三酯饮食治疗后并无改善,醋酸奥曲肽治疗效果也甚微。然而,她对抗纤溶治疗(反式-4-氨甲基环己烷羧酸,即氨甲环酸)在血清白蛋白和胃肠道出血方面有临床反应。她的病情仍时有加重,并持续存在淋巴细胞减少和慢性胸腔积液。
