[Immunological diagnosis of cutaneous lymphomas. II. Membrane receptor for Helix pomatia lectin on lymphocytes: a new immunohistological marker for T-lymphocytes and Sezary cells].

Lymphocytes carrying the receptor for helix pomatia lectin on their cytomembranes can be detected in lymphatic tissue and cutaneous T-cell lymphoma by means of peroxidase-labelled helix pomatia lectin. Cells positive for the HPL-receptor are identical with the population of T-lymphocytes, including their pathological variants, i.e. lymphoma cells and Sezary's cells.
