Mucosal spots, or "freckles," surrounding the appendiceal orifice are an endoscopic feature of the cecum. These are clusters of 1 to 2 mm round or oval slightly raised spots, each with a pale center and an erythematous border. They correlate microscopically with subepithelial and submucosal lymphoid follicles. The freckling pattern, identified in about one third of colonoscopies, was seen best with the videoendoscope and was identified more commonly in patients with systemic illness. Recognition of mucosal freckling around the appendiceal orifice helps identify the cecum and may be useful in the evaluation of cecal and appendiceal pathology.
阑尾开口周围的黏膜斑，即“雀斑”，是盲肠的一种内镜特征。这些是由1至2毫米的圆形或椭圆形略微隆起的斑点组成的簇，每个斑点都有一个浅色中心和一个红斑边界。它们在显微镜下与上皮下和黏膜下淋巴滤泡相关。这种雀斑样形态在约三分之一的结肠镜检查中可见，使用视频内镜观察最佳，且在患有全身性疾病的患者中更常见。识别阑尾开口周围的黏膜雀斑有助于识别盲肠，可能对评估盲肠和阑尾病变有用。
