A teen-aged girl presented with a painless swelling of the right submandibular gland. Neck ultrasonography showed a 1-cm intraglandular cyst compatible with a mucocele, but no further treatment was proposed. Three years later, because the lesion was still present without other clinical symptoms, the patient was referred to our institution. A computed tomographic (CT) image of the head and neck showed an intraglandular calcified nodule of 1.5 cm in size, consistent with a salivary duct lithiasis (Figure, A). A right submandibulectomy was performed under general anesthesia. The macroscopic analysis found an intraglandular calcified nodule with no modification in the surrounding gland.
