Abstract: We examined a 6‐year‐old boy with seborrheic dermatitislike redness of the face, scaling of the scalp, and palmoplantar keratoderma. Skin biopsy showed hyperkeratosis, parakeratosis, follicular plugging, and mild upper dermal perifoUicular mononuclear inflammatory infiltrate, which are compatible with the diagnosis of pityriasis rubra piiaris. Immunologic studies revealed normal values of peripheral B and T lymphocytes. The spontaneous activity of T suppressor cells was activated and the function of T helper cells was impaired, however.
