Cellular reaction to autologous tumor tissue followed by "skin window" technique in orofacial tumors

In a sample of patients with pseudotumors and benign and malignant tumors of the orofacial region there has repeatedly been investigated, after radical surgery, the cell reaction to autologous tumor tissue applied at indicated time intervals on a small skin lesion. The prognostically favorable picture of a cellular-type hypersensitivity reaction with massive participation of lymphoid cells and basophil granulocytes was only found in some basaliomas and leukoplakias. Conversely, spinocellular carcinomas are, irrespective of localization, characterized by areactivity.
