Adenocarcinoma of the appendix.

Area of Science:

• Gastroenterology
• Surgical Oncology

Background:

• Adenocarcinoma of the appendix is a rare malignancy.
• It often presents insidiously, mimicking acute appendicitis.

Observation:

• Three cases of appendiceal adenocarcinoma are presented.
• Diagnosis was confirmed histologically after appendectomy for acute appendicitis.
• Clinical presentation included acute appendicitis in all three cases.

Findings:

• One patient had a Dukes' B tumor and underwent right hemicolectomy.
• Another patient with likely Dukes' B disease did not have further surgery due to dementia.
• The third patient presented with advanced disease.

Implications:

• A review of 145 cases suggests right hemicolectomy for non-Dukes' A appendiceal adenocarcinoma in fit patients.
• Prognosis for appendiceal carcinoma is comparable to colorectal carcinoma.
• Early diagnosis and appropriate surgical management are crucial for improved outcomes.
