Low-grade appendiceal mucinous neoplasm (LAMN) is a relatively rare, non-invasive appendiceal tumor. We experienced a case of LAMN that led to surgery after 12 years of no treatment. Until now, LAMN has been reported to progress more slowly than other tumors, but there have been no reports of long-term follow-up of appendiceal tumors without treatment. Although the tumor had grown over the course of 12 years, there was no mixing or migration of other histological types, and it did not lead to pseudomyxoma peritonei. As this course is considered to be relatively rare, we report it along with a literature review.
低级别阑尾黏液性肿瘤（LAMN）是一种相对罕见的非侵袭性阑尾肿瘤。我们遇到了一例LAMN患者，在未接受治疗12年后才接受手术。到目前为止，据报道LAMN的进展比其他肿瘤更缓慢，但尚无关于未治疗的阑尾肿瘤长期随访的报道。尽管肿瘤在12年的病程中有所生长，但没有其他组织学类型的混合或转移，也未导致腹膜假黏液瘤。由于这种病程被认为相对罕见，我们将其与文献综述一并报告。
