Pleural dissemination of thymoma showing tumor regression after combined corticosteroid and tacrolimus therapy.
We present the case of an elderly woman with myasthenia gravis who had pleural dissemination of thymoma reduced by treatments with a moderate dose of corticosteroids and a conventional dose of tacrolimus. A maintenance dose of prednisolone for myasthenia gravis could not shrink the size of the disseminated thymoma, but prednisolone (>30 mg daily) succeeded in reducing the size of the tumor. Moreover, a combination with tacrolimus enabled the daily dose of prednisolone to be tapered off without recurrence of myasthenia gravis, and the disseminated thymoma almost disappeared. A moderate or higher dosage of corticosteroids with tacrolimus may, in some cases, be an effective procedure for pleural dissemination of thymoma. Treatment should be undertaken on a trial basis for patients not indicated for surgery, radiotherapy, or chemotherapy.
