Submucosal abscesses are rare in the gastrointestinal tract. Although they have been reported throughout the tract, occurrence within the appendix has not been described.
Case report and review of the current literature.
We present the case of a patient with a periappendiceal mass found incidentally on workup for anemia. An ileocecectomy was performed for presumed cecal neoplasm. Histologic examination showed a submucosal periappendiceal abscess with no evidence of malignancy.
This case is unique because although appendiceal abscesses often occur as a result of acute appendicitis, our patient presented with an incidental periappendiceal submucosal abscess, not preceded by any gastrointestinal infection or surgery. Periappendiceal submucosal abscess should be included in the differential diagnosis of masses found on colonoscopy.
黏膜下脓肿在胃肠道中较为罕见。虽然它们在整个消化道中均有报道，但阑尾内的黏膜下脓肿尚未被描述。
病例报告并复习当前文献。
我们报告了 1 例患者，其因贫血进行检查时偶然发现阑尾周围肿块。行回盲部切除术以治疗疑似盲肠肿瘤。组织学检查显示阑尾黏膜下周围脓肿，无恶性证据。
该病例较为独特，因为尽管阑尾脓肿常由急性阑尾炎引起，但我们的患者表现为偶然发现的阑尾周围黏膜下脓肿，之前没有任何胃肠道感染或手术史。阑尾周围黏膜下脓肿应纳入结肠镜检查发现的肿块的鉴别诊断中。
