Monoclonal antibody studies in the skin lesions of patients with anetoderma.

In all five patients studied, monoclonal antibody studies of cryostat sections of skin biopsy specimens of anetoderma lesions revealed inflammatory cells reacting with anti-Leu-1, pan-T-cell antibody, and anti-Leu-3a, the helper/inducer T-cell antibody. Small numbers of suppressor cells were present in only three biopsy specimens. Four specimens showed OKM1, antibody-reacting cells (monocytes). The age of the lesion was not correlated with inflammation or the T-cell subsets identified.
