Oral papillary squamous cell carcinoma: case report and literature review
Main Article Content
Abstract
Introduction: Papillary squamous cell carcinoma is a tumor that affects the upper aerodigestive tract and rarely affects the oral cavity. Objective: to report a case of oral papillary squamous cell carcinoma and review the literature about this condition. Case report: We present a case of a 73-year-old male patient with two intraoral lesions of 3 months of evolution. There was an exophytic ulcero-vegetating lesion measuring 1.5 cm in the left alveolar ridge region/mouth floor and an ulcerated lesion in the left retromolar region measuring 1cm. Moreover, there was a symptomatic hardened lymph node on the level 1B of the left side, measuring 4x3cm. Both intraoral lesions were biopsied and the one that affected the alveolar ridge/mouth floor was diagnosed as papillary squamous cell carcinoma. The tumor was staged as T3N2aM0 (III-B) and the treatment employed was chemotherapy associated with radiotherapy. After 2 years of follow-up, the patient is alive and without evidence of disease, lymph node or distance metastases. Conclusion: The papillary squamous cell carcinoma remains a rare tumor in the oral cavity with few reported cases. This case report highlights the importance of histopathological examination for the accurate diagnosis and its role in determining appropriate treatments and prognosis.
