Abstract

Aim: Glomus Caroticum is a chemoreceptor organ located in the adventitia of the vessel, usually at the bifurcation of the arteria carotid communis. Normally about 2 mm in diameter, it consists of spindle-like supporting cells, clusters of cells surrounding round or polygonal mother cells. Glomus Caroticum Tumors are rare, with an incidence of 1 per 100,000 population, accounting for approximately 50-60% of head and neck paragangliomas. Assessing the preliminary diagnostic accuracy of Glomus Caroticum Tumors using perioperative pathology samples.

Material and Methods: Over the last eight years, seven patients with preliminary diagnoses of Glomus Caroticum Tumors were operated. Surgical procedures were planned based on physical examinations and patient complaints. Five of the patients were female and two of the patients were male aged 25, 33, 34, 53, 57and 71 respectively. They presented with common symptoms including dyspagia, hoarseness and unilateral neck mass. Excisional biopsy materails were examined by expert pathologists.

Results: Pathology results confirmed the preliminary diagnosis of Glomus Caroticum Tumor in 5 out of 7 cases. One case was report as vascular malformation, while the other was reported as lymph nodes showing reactive changes.

Conclusion: Taking all factors into account, the accuracy of the preliminary diagnoses based on clinical evaluations stands at %71.44. When preoperative CT scans examined, five of them was correctly diagnosed and consistent with Shamblin classification. The discrepancy arises because the masses in the other two patients were predominantly located on the common carotid artery.
