Mucoceles resulting from cystadenomas of the appendix are uncommon. Although rare, rupture of the mucoceles can occur with or without causing any abdominal complaint. There are several reports associating colonic malignancy with cystadenomas of the appendix. Herein, we report an unusual and interesting case of right inguinal hernia associated with left colon cancer.
A case of ruptured mucocele resulting from cystadenoma of the appendix was presented as right inguinal hernia in a 70-year-old male. The patient underwent colonoscopy, x-ray, ultrasound and computed tomography. Localized pseudomyxoma peritonei associated with adenocarcinoma of the descending colon was diagnosed. The patient underwent segmental resection of the colon, appendectomy, debridement of pseudomyxoma and closure of the internal ring of right inguinal canal. He is free of symptoms in one year follow-up.
Synchronous colon cancer may occur in patients with appendiceal mucoceles. In such patients, the colon should be investigated and colonoscopy can be performed meticulously in cases of ruptured mucoceles and localized pseudomyxoma peritonei. Surgical intervention is the current choice of management.
阑尾囊腺瘤导致的黏液囊肿并不常见。尽管罕见，但黏液囊肿破裂可能发生，且可能伴有或不伴有任何腹部症状。有几篇报道将结肠恶性肿瘤与阑尾囊腺瘤联系起来。在此，我们报告一例与左结肠癌相关的罕见且有趣的右腹股沟疝病例。
一名70岁男性患者，阑尾囊腺瘤导致的黏液囊肿破裂，表现为右腹股沟疝。患者接受了结肠镜检查、X线检查、超声检查和计算机断层扫描。诊断为降结肠癌伴局限性腹膜假黏液瘤。患者接受了结肠节段性切除术、阑尾切除术、假黏液瘤清创术以及右腹股沟管内环关闭术。在一年的随访中，他没有症状。
阑尾黏液囊肿患者可能发生同步性结肠癌。对于此类患者，应检查结肠，在黏液囊肿破裂和局限性腹膜假黏液瘤的病例中可仔细进行结肠镜检查。手术干预是目前的治疗选择。
