Two cases of rectal xanthomas are described. One case is that of a 56-year-old Japanese man in whom multiple yellowish spots measuring approximately 3 to 5 mm were observed in the rectum during colonoscopy. The other case is that of a 78-year-old Japanese man in whom colonoscopy showed a whitish plaque of 4 mm in diameter in the rectum. Biopsy examinations performed on both patients revealed the deposition of xanthoma cells within the rectal mucosa. Within the gastrointestinal tract, xanthomas most frequently arise in the stomach, whereas the colorectum is rarely affected. Despite this infrequency, the two cases indicate that xanthomas should be recalled when yellowish to whitish lesions are observed in the colorectum.
本文描述了两例直肠黄色瘤病例。一例是一名56岁的日本男性，在结肠镜检查时，其直肠内发现多个大小约为3至5毫米的淡黄色斑点。另一例是一名78岁的日本男性，结肠镜检查显示其直肠内有一个直径为4毫米的白色斑块。对两名患者进行的活检检查均显示直肠黏膜内有黄色瘤细胞沉积。在胃肠道中，黄色瘤最常发生于胃，而结直肠很少受累。尽管发生率较低，但这两例病例表明，当在结直肠中观察到淡黄色至白色病变时，应考虑黄色瘤的可能。
