The brown bowel syndrome (BBS) is a rare disease characterized by malabsorption and accumulation of lipofuscin in the smooth muscle cells of the muscularis externa of the small intestine. Recently, we incidentally observed a case of BBS in a colon operated on because of a neoplasm. Our ultrastructural investigation, which demonstrated changes in the mitochondria, further supports the significance of mitochondrial damage in BBS.
棕色肠道综合征（BBS）是一种罕见疾病，其特征为小肠外肌层平滑肌细胞中脂褐素的吸收不良和蓄积。最近，我们偶然在一名因肿瘤接受结肠手术的患者中观察到一例BBS。我们的超微结构研究显示了线粒体的变化，进一步支持了线粒体损伤在BBS中的重要性。
