[Lymphocyte subpopulations in patients with skin basalioma of the trunk].

In 11 male patients with histologically proven basal cell epithelioma of the trunk, we studied the distribution of peripheral lymphocyte subsets. All of the patients revealed pathological T-cell subsets, 6 of them showing reduced numbers of CD8 and 5 decreased numbers of CD 4 cells. 2 patients had taken arsenic; in 2 patients we diagnosed a further tumor of some other origin.
