Sialolithiasis is the most common disease of the salivary glands. Sialolithiasis usually develops in the major salivary glands, and rarely in the minor salivary glands, with only 2% of all cases of sialolithiasis occurring in the minor salivary glands and sublingual glands. Sialoliths in the minor salivary glands result in few or no clinical symptoms and are seldom identified on imaging.

Case presentation

We report herein our experience with a case of minor salivary gland sialolithiasis in a 67-year-old woman. On examination, an elastic soft, mobile, and well-circumscribed mass was palpable within the left upper lip. Ultrasound examination revealed a hypoechoic mass with heterogeneous internal echoes. The mass was excised under local anesthesia. Based on histopathological findings, a diagnosis of minor salivary gland sialolithiasis was established.


Diagnosis of minor salivary gland sialolithiasis is challenging due to the difficulty of detecting sialoliths on imaging. A well-circumscribed mass was detected in the upper lip, and ultrasound examination revealed a round lesion, raising the suspicion of a benign tumor. Other diseases that can develop at the upper lip are calcified lymph node, phlebolith, fibroma, pleomorphic adenoma, myxoma, vascular malformation, salivary gland tumor, non-specific sialadenitis, and malignant tumor. Surgical excision is the favored approach for confirming a diagnosis of intramucosal nodular lesions.
