Introduction: Parotid lithiasis, or sialolithiasis, is an inflammatory condition of the parotid gland caused by a stone obstructing its excretory duct. Representing 4-10% of salivary gland lithiasis, it rarely reveals underlying diabetes mellitus, as in the case we present here.

Observation: A 44-year-old man with a family history of type 1 diabetes, who consulted for a right parotid swelling evolving for 2 days in a febrile context. Physical examination revealed a firm, approximately 3 cm, right parotid swelling with overlying inflammatory signs. Purulent discharge was observed from the opening of the right Stensen’s duct, associated with a 1 cm trismus, but no facial paralysis was present. Cervical ultrasound showed a heterogeneous, enlarged right parotid gland with a stone in a dilated Stensen’s duct. The patient was admitted in our department and started on Amoxicillin-clavulanic acid. The initial Lab results revealed a biological inflammatory syndrome and elevated blood glucose levels, along with a disturbed glycemic profile and a glycated hemoglobin of 6%. An endocrinology opinion was requested and he was placed on insulin therapy with good education regarding his incidentally discovered diabetes. The patient’s condition improved significantly, and he was discharged on the 7th day with antibiotic coverage and a follow-up appointment with the endocrinology department for diabetes management.

Conclusion: This observation underlines the importance of looking for diabetes mellitus in patients with lithiasic parotiditis, particularly when associated risk factors are present. Early recognition of diabetes allows for timely intervention and prevention of long-term complications.
