IV. Multiple glomus tumors in the head and neck

Area of Science:

• Otolaryngology
• Neurosurgery
• Oncology

Background:

• Glomus tumors in the head and neck are rare.
• Multiple glomus tumors present unique diagnostic and management challenges.

Purpose of the Study:

• To investigate the incidence and patterns of multiple glomus tumors in the head and neck.
• To outline the recommended clinical evaluation and management strategies for these tumors.

Main Methods:

• Retrospective analysis of 76 head and neck glomus tumors.
• Review of clinical, neurological, and neuroradiological evaluations.
• Correlation of tumor location, multiplicity, and associated conditions.

Main Results:

• Eight out of 76 (10.5%) glomus tumors were multiple.
• The most frequent association was with carotid body tumors.
• A common pattern involved ipsilateral glomus tympanicum and carotid body tumors.
• Associated malignancies were found in 8% of cases.

Conclusions:

• Glomus tumors exhibit a significant tendency for multicentricity.
• Comprehensive evaluation is crucial for identifying multiple lesions and associated malignancies.
• Management should prioritize resection of the most life-threatening tumors first.
