Primary mucinous adenocarcinoma is a rare adnexal neoplasm of eccrine gland. Fewer than 200 cases are reported in literature. Clinically, it can be mistaken as a benign lesion. The primary challenge in these lesions is to differentiate these rare primary lesions from more frequent mucinous secondary deposits. Morphologically, they are similar to metastatic deposits of mucinous carcinoma from other viscera such as breast, lung, or gastrointestinal tract. Use of ancillary techniques and a thorough metastatic work up are mandatory to differentiate these lesions from metastases. We report a case of primary mucinous carcinoma of nasojugal region in a 51-year-old female. It was diagnosed on fine-needle aspiration cytology, and later, the lesion was excised and diagnosis confirmed on histopathological examination and immunohistochemistry.

An asymptomatic 79-year old woman presented with a 40 mm pancreatic cystic lesion, located in the pancreatic body-tail and consistent with branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) without "high risk stigmata". During a 4-year follow-up period, imaging showed no mural nodules or main pancreatic duct dilation, and serum CEA and CA19.9 were within normal range.

Objective: We aimed to explore the abnormal pathology findings in appendix specimens removed based on intraoperative abnormal appearance during elective surgery for benign gynaecological conditions by a minimally invasive gynaecologist, as well as the associated complication rate.
Materials And Methods: This retrospective cohort study was conducted in a tertiary referral surgical centre for benign gynaecological conditions between the years 2004-2023. It included patients who underwent appendicectomy by a trained minimally invasive gynaecologist based on observations during surgery for benign gynaecological conditions.
Peritoneal Dissemination and Malignant Ascites in Duodenal Cancer Successfully Treated With Adoptive Cell Therapy Using WT1- and MUC1-Pulsed Dendritic Cells and Activated T Cells With No Adverse Effects: A Case Report.

A satisfactory treatment for the dissemination of duodenal cancer has not yet been established. We describe a case of peritoneal dissemination and malignant ascites in duodenal cancer that was successfully treated with adoptive cell therapy with no adverse effects. A 72-year-old Japanese male patient with primary duodenal cancer with distal lymph node metastases received chemotherapy with S-1, an oral pyrimidine fluoridederived agent, and oxaliplatin after gastrojejunal bypass, which resulted in tumor shrinkage; however, peritoneal dissemination developed.

Introduction: Mucinous appendiceal neoplasms are unique tumors in which >50 % of the tumor volume is composed of extracellular mucin. They may present as an unruptured mucin-filled appendix or, more commonly, with peritoneal metastases after rupture or transmural invasion of the primary tumor. This case report describes a case of presumed ovarian malignancy with final pathologic diagnosis of low grade appendiceal mucinous neoplasm.
