Superior Thyroid Cornu Osteoma Presented as a Neck Mass

Osteomas are benign and generally slow-growing, consisting of densely sclerotic and well-defined bones that are typically located in the skull and facial bones. We present a 19-year-old female patient with a painless lump on one side of the neck. Computed tomography was performed with a report of tumor growth in the thyroid cartilage. The patient underwent an external neck approach for excision of the tumor and the his- topathological diagnosis confirmed the diagnosis of osteoma. Thyroid cartilage osteomas should be taken into consideration when dealing with a patient presenting with a neck mass.
