Appendiceal carcinoma mimicking primary bladder cancer

Area of Science:

• Gastroenterology
• Urology
• Oncology

Background:

• Appendiceal adenocarcinoma is a rare malignancy.
• Invasion of adjacent organs, such as the bladder, is uncommon.
• Accurate initial diagnosis is crucial for appropriate management.

Observation:

• A patient presented with symptoms initially suggestive of invasive bladder cancer.
• Preoperative pelvic irradiation was administered based on the initial diagnosis.
• Surgical exploration revealed a primary appendiceal neoplasm invading the bladder.

Findings:

• The patient underwent a right hemicolectomy and en bloc partial cystectomy.
• This surgical approach successfully addressed the appendiceal adenocarcinoma invading the bladder.

Implications:

• This case highlights the importance of considering rare differential diagnoses in oncology.
• The described surgical treatment is recommended for appendiceal adenocarcinoma with bladder invasion.
• Further research may elucidate optimal management strategies for similar rare presentations.
