A 70-year-old female with uncontrolled diabetes mellitus presented with complaints of burning mouth. Generalized mucositis was seen on the lower labial mucosa extending from commissure to commissure (probably related to the anemic condition). Indentations were noted along anterior and lateral borders of the tongue corresponding to the gaps in her teeth, along with erythema of tongue margins. This could be correlated to her nutritional state, Hb, and her uncontrolled diabetes. Detailed questioning revealed that the patient had prior episodes of oral ulcers [].\nDifferential diagnosis: Diabetic mucositis.
