Basaloid squamous cell carcinoma of the tonsil.

Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of squamous cell carcinoma that mainly arises in the upper aerodigestive tract. The tonsil is a rare site of BSCC development and only fourteen cases have been reported in the international literature. We report here on the case of a 56-year-old man who presented with mild dysphagia. Computed tomography and examination of the oropharynx revealed a suspicious-looking, bulky mass on the right tonsil. Histopathological examination confirmed the presence of BSCC. The patient had cervical lymph node metastases and pulmonary metastases and was treated with chemotherapy and concurrent radiation. Despite the metastases the patient is still alive 3 years after the initial diagnosis.
