A hidden giant: Presentation of a large sublingual Pleomorphic Adenoma

Abstract

INTRODUCTION: Minor salivary gland neoplasms are an extremely rare finding, characterized by tumors that are mostly malignant (>70-90%), especially in the sublingual glands, with a greater prevalence in adults over 40 years of age, of uncertain etiology. Some factors such as cigarettes, radiation, trauma, genetics and others are associated with its development. CLINICAL CASE: a young patient of 20 years of age with a submental mass of 5 years of evolution, which occupies the entire floor of the mouth, reporting progressive dysphagia and sensation of a foreign body when swallowing; On physical examination, he presented dysphonia, elevation of the base of the tongue, contacting the lingual surface of the epiglottis due to a soft, mobile, non-painful mass. In contrast-enhanced neck tomography, a space-occupying lesion measuring 8*7cm was observed, rounded, well-defined, heterogeneous, with hypodense images inside. Inconclusive fine needle aspiration puncture was performed. Oncological resection of the floor of mouth tumor was performed, reporting histopathological findings: cellular pleomorphic adenoma without findings of malignancy. CONCLUSION: Early diagnosis and complete surgical removal are essential for a good prognosis. Long-term follow-up is important to detect recurrence or malignant transformation.
