Cells with positive Dopa--reaction in the infiltrate of basal cell epithelioma (bce).
Histological sections of basal cell epithelioma (bce) reveal 4 groups of Dopa-positive cells: 1. epidermal melanocytes; 2. cells within a thin subepidermal layer; 3. cells in the dense cellular infiltrate of the corium 4. cells within tumour tissue. In general the cells of groups 2 and 3 are mastocytes. The total number of Dopa-positive cells, especially those of group 3, is increased in the presence of eosinophilic granulocytes.
