Mesenteric desmoid tumor after robot-assisted laparoscopic cystectomy with bladder replacement: a case report

Area of Science:

• Oncology
• Surgical Pathology

Background:

• Desmoid tumors are rare neoplasms linked to genetic factors, trauma, and hormones.
• Surgical trauma is a known trigger for desmoid tumor development.
• While laparoscopic surgery is common, desmoid tumors post-robot-assisted procedures are infrequently reported.

Observation:

• This report details a rare case of a mesenteric desmoid tumor.
• The tumor developed after robot-assisted laparoscopic cystectomy for bladder cancer.
• Distinguishing desmoid tumors from cancer recurrence after surgery is clinically significant.

Findings:

• A mesenteric desmoid tumor was diagnosed following robot-assisted laparoscopic cystectomy.
• The tumor was successfully resected using a combined minilaparotomy and laparoscopic approach.
• Accurate differentiation from bladder cancer recurrence was crucial for treatment planning.

Implications:

• This case underscores the importance of considering desmoid tumors in the differential diagnosis of masses after robotic surgery.
• It highlights a rare complication following cystectomy for bladder cancer.
• The findings contribute to understanding desmoid tumor development in the context of minimally invasive oncologic surgery.
