Mucinous and Nonmucinous Appendiceal Adenocarcinomas: Different Clinicopathological Features but Similar Genetic Alterations [PDF]

Modern Pathology, 2002
The genetic alterations of appendiceal carcinomas have not been reported in detail. We studied the clinicopathological factors and genetic alterations including microsatellite instability, p53 overexpression, and mutations of the K-ras proto-oncogene of 30 appendiceal adenocarcinomas, consisting of 23 mucinous and 7 nonmucinous carcinomas. Sixteen (70%)

Low-Grade Appendiceal Mucinous Neoplasm Involving the Endometrium and Presenting with Mucinous Vaginal Discharge

Case Reports in Obstetrics and Gynecology, 2016
Primary appendiceal mucinous lesions are uncommon and represent a spectrum from nonneoplastic mucous retention cysts to invasive adenocarcinoma. Low-grade appendiceal mucinous neoplasms (LAMNs) represent an intermediate category on this spectrum and can ...

Mucinous adenocarcinoma of the cecal appendix

Revista de la Facultad de Medicina Humana, 2022
Cecal appendix adenocarcinoma occurs in approximately 0.1% to 0.2% of all appendectomies. One subtype, mucinous adenocarcinoma, represents 0.08% of all neoplasms. Diagnosis is usually incidental and surgery is the best treatment option.

The utility of PAX8 and SATB2 immunohistochemical stains in distinguishing ovarian mucinous neoplasms from colonic and appendiceal mucinous neoplasm

BMC Research Notes, 2019
Objectives It is challenging to distinguish between primary ovarian mucinous tumors and metastatic mucinous neoplasms from the lower gastrointestinal tract, including appendiceal tumors.

Classification of mucinous appendiceal neoplasm and pseudomyoxma peritonei

Journal of Pathology of Nepal, 2018
Mucinous appendiceal tumors are uncommon and include a wide spectrum of tumors whose classification remained controversial. Some of these mucin producing appendiceal tumors can disseminate to the peritoneal cavity leading to pseudomyxoma peritonei (PMP).

Prognostic Impact of Histologic Subtypes in Mismatch Repair‐Deficient/Microsatellite Instability‐High Colorectal Cancer: A Single‐Center Retrospective Study of 1127 Stage 0–IV Patients

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Deficient mismatch repair/microsatellite instability‐High (dMMR/MSI‐H) colorectal cancer (CRC) generally confers a favorable survival yet is paradoxically enriched for poorly differentiated (Por) histology, which is linked to aggressive behavior.

Mucocele of the Appendix Secondary to Chronic Appendicitis: A Case Report. [PDF]

Clin Case Rep
ABSTRACT Chronic appendicitis leading to mucocele of appendix, though rare and often mimicking malignancy, can present with benign histopathology. Multidisciplinary correlation of clinical, imaging, intraoperative, and histopathological findings is critical to avoid misdiagnosis and guide conservative management in atypical presentations.
