We screened for possible metastatic lesions with positron emission tomography and found an 11 mm nodule at the second cervical vertebra (Fig. 1a). Seven weeks after the IMRT irradiation, the patient developed large, tense bullae and erosion arising on erythematous plaque on the trunk and extremities (Fig. 1b). A biopsy specimen revealed prominent interface dermatitis and dense infiltration of eosinophils in the upper dermis (Fig. 1c).
