Mesoappendiceal paraganglioma.

D E Clark, J F Stocks, J L Wilkis

The American Journal of Gastroenterology

|May 1, 1985

Summary

This summary is machine-generated.

A rare 10-cm paraganglioma of the mesoappendix was surgically removed from an asymptomatic patient. This case and a literature review suggest these are aberrant retroperitoneal paragangliomas.

Area of Science:

Gastroenterology
Surgical Oncology
Pathology

Background:

Paragangliomas are rare neuroendocrine tumors typically arising in the adrenal medulla or sympathetic chain.
Gastrointestinal paragangliomas are exceptionally uncommon, with most reported cases involving the stomach, duodenum, or rectum.

Observation:

A 10-cm tumor of the mesoappendix, a rare location, was surgically resected from an 81-year-old asymptomatic woman.
The patient remained healthy 5 years post-surgery, indicating a favorable prognosis for this specific tumor type and location.

Findings:

Histological examination confirmed the tumor as a paraganglioma.
A review of five additional case reports of paraganglioma in the gastrointestinal tract distal to the duodenum was conducted.

Implications:

The authors propose that these rare gastrointestinal paragangliomas, particularly those in the mesoappendix, should be classified as aberrant retroperitoneal paragangliomas.
This classification may aid in understanding their embryological origin and guide future diagnostic and treatment strategies.
