Laryngeal Paraganglioma - A Rare Entity

Area of Science:

• Neuroendocrinology
• Oncology
• Head and Neck Surgery

Background:

• Laryngeal paragangliomas are rare, neural crest-derived neuroendocrine tumors originating from laryngeal paraganglia.
• These tumors most commonly occur in the supraglottis, with a mean age of onset at 44 years, and are more prevalent in females.

Observation:

• A case involved a 39-year-old female initially diagnosed with squamous cell carcinoma after tumor debulking and excision.
• The patient received one cycle of chemotherapy, leading to apparent complete resolution of the mass, confirmed by follow-up.
• Subsequent immunohistochemistry re-diagnosed the tumor as a laryngeal paraganglioma.

Findings:

• The initial histopathology suggested squamous cell carcinoma, but immunohistochemistry confirmed laryngeal paraganglioma.
• Chemotherapy appeared effective in resolving the laryngeal mass in this specific case.

Implications:

• This case raises questions about the efficacy of chemotherapy in managing laryngeal paragangliomas.
• Further investigation is warranted to determine the role and effectiveness of chemotherapy in the treatment protocols for laryngeal paragangliomas.
