title: [Actinic reticuloid. Immunohistochemical study].
abstract: A patient that fulfilled the clinical and histological features of actinic reticuloid has been studied. He presented a positive patch test for fragance mix. Typical cutaneous lesions were reproduced with a solar simulator. The immunochemical studies of the inflammatory infiltrates of these induced lesions gave a higher percentage of T8 in relationship to T4 lymphocytes. Most of the cells were HLA-DR positive. No clonality of these lymphocytes was detected. In the peripheral blood lymphocytes, an increased percentage of T8 lymphocytes was also observed.
