A Case of Toxic Epidermal Necrolysis Initially Affecting the Skin Site of Radiation Therapy for an Intra-cranial Post-transplantation Lymphoma

Abstract

We report a case of post-transplantation lymphoma (intra-cranial EBV-related malignant lymphoma) who developed toxic epidermal necrolysis (TEN) during concomitant phenobarbital administration and radiotherapy. The erythema exsudativum multiforme-like eruption first appeared on the site of radiation and extended to approximately 35% of the body surface. After stopping radiation therapy and all medications, including immunosuppressant, anticonvulsant, and diuretic drugs, treatment was successfully administered by systemic corticosteroids including semi-pulse therapy (500 mg of methylpredonisolone sodium succinate for 3 days).
