Ressecção de carcinoma de células escamosas em região de lábio inferior: relato de caso

Abstract

Squamous cell carcinoma is the most common malignancy in the oral cavity, affecting mainly men over the age of 60 years. The treatment of the tumor includes radiation therapy, chemotherapy, alone or in combination and surgery. The objective of this article is to report a clinical case of squamous cell carcinoma, where it was decided to perform a surgical excision of the lesion exclusively, since it was well defined. White female patient, 81 years old, without harmful habits, sought care with a report of acute pain, burning in the lower lip region for approximately one year, associated with dysphagia. During the clinical examination, an erythematous hyperplastic lesion was observed, 2 centimeters long, with well-defined borders, absence of central necrotic tissue surrounding the skin, red lip margin and lip mucosa. An incisional biopsy procedure was performed, which revealed a well-differentiated ulcerated squamous cell carcinoma. The treatment involved surgical excision under deep sedation, in which resection was performed, with safety margins of approximately 5 mm. After the end of the procedure, the material was collected and sent for histopathological examination to check the margins. Currently, the patient has no pain complaints or clinical signs of recurrence. It was noted in the presente clinical case that a recurrent trauma injury can progress to squamous cell carcinoma, and resection of the tumor with safety margins was effective in treating the patient.
