A technique for immunoultrastructural identification of T6-positive Langerhans cells and indeterminate cells in mycosis fungoides.
An immunoelectron microscopic method was developed using T6 antiserum in an immunoperoxidase technique to label the dendritic cells of the epidermis in mycosis fungoides (MF). The technique allows simultaneous identification of intracellular Birbeck granules and T6 membrane positivity. Ultrastructural examination of the epidermal infiltrate of MF, using this method, confirmed the T6-positive nature of Langerhans cells and indeterminate cells. All Sézariform and mature lymphocytes were T6-negative and a small population of T6-negative histiocytic cells were also observed.
