Right Ovary of LAMN Patient Which was Unremarkable- H & E- 40X
A case of low grade appendiceal mucinous neoplasm (LAMN) presented with right inguinal hernia with mucinous cystadenoma of the appendix as content.
Of the five cases, three had been diagnosed with LAMN, and two were diagnosed with serrated polyp.
They categorized non-carcinoid epithelial tumors of the appendix into eight histomorphological architectural groups: adenoma, serrated polyp, LAMN, high-grade appendiceal mucinous neoplasm (HAMN), mucinous adenocarcinoma (well/moderately/poorly differentiated), signet ring cell low-differentiated (mucinous) adenocarcinoma, signet ring cell (mucinous) adenocarcinoma, and adenocarcinoma (Table 2) (8).

In 2013, Nishikawa and colleagues identified GNAS mutations as common in LAMNs and suggested that mutant GNAS might play a direct role in mucin production (16).
Assessment of surgical margins is an integral part of pathologic tumor evaluation, and the evaluation of an appendix with an adenoma or LAMN includes reporting on the status of the margin.
Low-grade appendiceal mucinous tumors include those that are confined to the mucosa and that are classified as adenomas and those that display pushing or expansile invasion and can disseminate in the peritoneal cavity as pseudomyxoma peritonei, for which the term low-grade appendiceal mucinous neoplasm (LAMN) was proposed (1) and adopted by the World Health Organization.
