A Rare Case of Laryngeal Osteosarcoma Causing Diagnostic Challenges.

Laryngeal osteosarcomas are extremely rare. They cause diagnostic difficulty for the otolaryngologist and pathologist. Differentiation from sarcomatoid carcinoma is challenging but important, as clinical features and treatment strategies are different. Total laryngectomy is generally the preferred surgical approach for laryngeal osteosarcomas. Since lymph node metastasis is not expected, neck dissection is not needed. In this report, we present a case diagnosed with laryngeal osteosarcoma post the examination of the total laryngectomy specimen of a laryngeal tumor that could not be histopathologically differentiated by punch biopsy.
