Osteosarcoma of the larynx

Area of Science:

• Oncology
• Pathology

Background:

• Laryngeal neoplasms are categorized into epithelial and non-epithelial types.
• Non-epithelial neoplasms include rare tumors like osteosarcomas.
• Treatment for laryngeal osteosarcoma typically involves surgery, with adjuvant therapies debated.

Observation:

• A rare case of laryngeal osteosarcoma in a female patient is presented.
• Diagnostic difficulties arose, with initial biopsy showing no malignancy despite clinical suspicion.
• Radical surgical treatment (complete laryngectomy) was performed without cervical lymph node dissection.

Findings:

• Postoperative histopathological examination confirmed laryngeal osteosarcoma.
• Immunohistochemistry, utilizing vimentin and Ki67, was crucial for diagnosis.
• The patient experienced no local recurrence or distant metastases during follow-up.

Implications:

• This case underscores the importance of comprehensive histopathological evaluation for rare laryngeal tumors.
• It highlights potential diagnostic discrepancies between biopsy and surgical specimens.
• Successful surgical management of laryngeal osteosarcoma without adjuvant therapy is demonstrated.
