This paper aims to describe a case of a large submandibular sialolith. A 53-year-old Caucasian female looked for for her dentist complaining of xerostomia, pain and swelling in the floor of the mouth, mainly observed during meals. The physical exam revealed a tender swelling on palpation in the left submandibular region, and also a firm intraoral swelling was detected in the left sublingual region. It was possible to draw pus from the submandibular gland. Mandibular occlusal radiography showed an extensive cylindrical and elongated, well-defined radiopaque image in the floor of the mouth. The association of clinical and radiographic findings led to the diagnosis of salivary calculus. The lesion was submitted to surgical excision under local anesthesia and the submandibular gland was maintened. Macroscopic analysis revealed a yellow and hard in consistency specimen, measuring 2.2 cm in length, and microscopic analysis revealed the presence of concentric laminations of calcified material associated with . The patient is being followed up for 2 years and 8 months, with no complaints of salivary flow or gland dysfunction, without gland swelling and no radiographic changes. Despite it being a large sialolith, its location near the exit of the duct allowed a conservative treatment with satisfactory aesthetic and functional results for the patient.
