A 70-year-old man is at his dermatologist’s office for the treatment of a severely pruritic erythroderma with scaling on his buttocks that has been slowly progressing over the past two weeks. The patient works as a truck driver and has a history of hypertension treated with enalapril. The patient reports having tried an over-the-counter cream on the rash without improvement. The vital signs are within normal range. On physical exam, he has multiple confluent and well-demarcated pink patches on his buttocks and legs with some scaling and enlarged inguinal lymph nodes. The dermatologist orders a skin biopsy that reveals Pautrier microabscesses. What is the most likely diagnosis?
