Diagnosis and management of oral ulcerations associated with mycophenolate mofetil in kidney transplantation.

AIMS The final diagnosis of oral mucosal ulcerations in solid organ transplant recipients represents a challenge. We describe a unique case of oral ulceration related to mycophenolate mofetil (MMF) toxicity, 11 years after kidney transplantation, whose dose reduction was sufficient to resolve it. METHODS AND RESULTS A 54-year-old female patient, who underwent kidney transplantation 11 years ago, presents multiple ulcers on the buccal mucosa bilaterally, soft palate and tongue dorsum, for 8 months, with moderate pain. The diagnosis of oral ulcerations associated with MMF therapy was assumed by excluding infection and malignancy diagnosis. After MMF dose reduction, the oral ulcers healed utterly. CONCLUSIONS MMF toxicity manifested as oral ulcers. Reduction or discontinuation of MMF therapy should be considered in a patient with refractory oral ulcers and a negative workup for other causes.
