Papulosquamous dermatitis with atypical lymphocytes

    A 69 year-old female presented with psoriasiform plaques of 1.5 years of evolution. This began on the arms and spread to the trunk, head and lower extremities. Alopecia was not noted on the scalp areas. Mucous membranes were not involved. First biopsy showed an atypical folliculotropic infiltrate; and the second one showed features of papulosquamous dermatitis with atypical lymphocytes. Treatment with topical steroids, NB-UVB and Methotrexate did not help to improve at all.

    Case to be discussed at upcoming Dermpedia Cutaneous Hematopathology CME Course in Scottsdale, AZ
