Abstract:
Mucinous cystadenoma is a rare lesion of the vermiform appendix and is seldom diagnosed before surgery, although radiologic and ultrasonographic findings have been reported. We present the case of a 65-year-old female with rheumatoid arthritis who presented with general malaise, poor appetite, fever, and right upper and lower quadrant pain of about one week's duration. Abdominal sonography and computed tomography revealed an 8 x 4 x 3 cm cystic lesion of the appendix. Laparoscopic evaluation confirmed this finding and the lesion was resected without rupturing the tumor during manipulation. Laparoscopic surgery provides the advantages of good exposure and evaluation of entire abdominal cavity, as well as more rapid recovery. It is important to avoid tumor rupture during manipulation, and formation of pseudomyxoma peritonei, in case the tumor is malignant.
Insights
A rare appendiceal mucinous cystadenoma was diagnosed in a 65-year-old female using imaging and confirmed with laparoscopic surgery. The case highlights the importance of careful surgical technique to prevent complications like pseudomyxoma peritonei.
Area of Science:
- Gastroenterology
- Surgical Oncology
Background:
- Mucinous cystadenoma of the vermiform appendix is a rare appendiceal neoplasm.
- Preoperative diagnosis is infrequent, often relying on advanced imaging modalities.
Observation:
- A 65-year-old female with rheumatoid arthritis presented with constitutional symptoms and abdominal pain.
- Abdominal sonography and CT revealed an 8 x 4 x 3 cm cystic appendiceal lesion.
Findings:
- Laparoscopic evaluation confirmed the cystic appendiceal lesion.
- Surgical resection was performed laparoscopically, avoiding tumor rupture.
Implications:
- Laparoscopic surgery offers excellent visualization and rapid recovery for appendiceal lesions.
- Careful surgical handling is crucial to prevent tumor rupture and the potential development of pseudomyxoma peritonei, especially in malignant cases.
