SIALOLITHIASIS OF MINOR SALIVARY GLAND IN THE BUCCAL MUCOSA: A CLINICAL FINDING

Sialolithiasis is the most common salivary gland disease, represented by a solid structure composed of calcium phosphate and organic matrix that may cause obstructive sialadenitis of the affected gland. Regularly diagnosed in the submandibular gland duct, it does not exhibit age or sex predilection. A 43-year-old female patient attended for dental evaluation had a small single asymptomatic yellow nodule with fibrous consistency in the buccal mucosa. An excisional biopsy was performed with clinical hypothesis of fibrous hyperplasia and lipoma. The histopathologic analysis showed an acellular mineralized tissue. The final diagnosis was sialolithiasis of the minor salivary gland. Sialolithiasis of the minor salivary gland is a rarely diagnosed disease and more commonly observed in the upper lip and buccal mucosa, suggesting its inclusion in the differential diagnose of minor salivary glands lesions, and this report emphasizes the importance of a complete clinical examination since it was a clinical finding.
