Chemodectomas: a review of 17 cases

Area of Science:

• Oncology
• Neurosurgery
• Pathology

Background:

• Chemodectomas, rare neuroendocrine tumors, originate from paraganglia.
• This study analyzes 17 cases managed at University College Hospital, Ibadan.

Observation:

• Carotid body tumors (48%) and glomus jugulare (36%) were the most frequent types.
• These tumors predominantly affected younger individuals with equal sex distribution.
• Subglottic, abdominal, and multicentric tumors were also observed.

Findings:

• Operative mortality was exclusively associated with carotid body tumors (50% incidence).
• Postoperative bleeding represented the primary complication across all chemodectoma cases.
• Younger age groups were disproportionately represented in the observed cases.

Implications:

• Clinical presentation, embryology, and pathophysiology of chemodectomas are discussed.
• Management decisions for chemodectomas necessitate careful consideration of surgical risks versus benefits.
• Further research into optimizing treatment strategies for chemodectomas is warranted.
