PLEOMORPHIC ADENOMA OF MINOR SALIVARY GLAND IN THE BUCCAL MUCOSA: A CASE REPORT

Pleomorphic adenoma (PA) is the most common benign salivary gland neoplasm, affecting mainly the parotid gland. It affects individuals within a wide age range, with a slight predilection for the female sex. A-43-year-old woman presented with a single asymptomatic normochromic nodule in the buccal mu...

Description
Summary:Pleomorphic adenoma (PA) is the most common benign salivary gland neoplasm, affecting mainly the parotid gland. It affects individuals within a wide age range, with a slight predilection for the female sex. A-43-year-old woman presented with a single asymptomatic normochromic nodule in the buccal mucosa that appeared 3 years earlier. The diagnostic hypotheses were fibroma and PA. The lesion was biopsied, and the histopathologic analysis revealed a benign neoplasm characterized by proliferation of epithelial and myoepithelial cells, forming islands and ductal structures in a stroma with fibrous and hyaline areas. The final diagnosis was PA, and the tumor was surgically removed. The patient remains under follow-up, and there are no signs of relapse. This case shows that PA can occur in the minor salivary glands and emphasizes its differential diagnosis with other tumors.
