title: Borderline tuberculoid leprosy mimicking mycosis fungoides.
abstract: A 65-year-old unemployed man, originally from Michoacán and currently living in Toluca, state of Mexico, presented for medical consultation for disseminated dermatosis in all body segments. The condition was limited to the head and neck, was bilateral and symmetrical, and was characterized by infiltrated and confluent erythematous-edematous plates of diverse diameter covering 90% of the upper and lower extremities (Figure 1). The ailment had 2 years' evolution and a progressive course. The patient was diagnosed in private practice as having atopic dermatitis. After exacerbation of symptoms, he was treated with deflazacort and hydroxychloroquine with no improvement. Results from lesion biopsies revealed sarcoidal granulomas and the patient was therefore referred to the dermatology department at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán for further study and treatment with the presumptive diagnosis of mycosis fungoides vs sarcoidosis.
