A Patient with Refractory Psoriasis Who Developed Sebaceous Carcinoma on the Neck during Cyclosporine Therapy and Showed Rapid Progression

Abstract

We report a patient who developed sebaceous carcinoma on the neck during therapy with immunosuppressive agents (cyclosporine, corticosteroid, methotrexate) for refractory psoriasis vulgaris, which showed rapid enlargement, leading to a fatal outcome. Multiple-organ metastases were detected. Weekly carboplatin + paclitaxel therapy resulted in the disappearance of tumor cells, but the patient died of febrile neutropenia. The development of sebaceous carcinoma is rare among psoriasis patients receiving immunosuppressive agents including cyclosporine.
