Lysozyme and alpha-1-antichymotrypsin depositions were recorded by means of the PAP technique from benign and malignant fibrohistiocytic tumours. These depositions were seen in relation to lesions with histiocytic reactions. The findings indicate that the detection of these markers support the solution of problems of differential diagnosis. An important role is particularly played by demonstration in fibroblastic elements within the neoplasm proper. The results also suggest the possible existence of an undifferentiated precursor cell.
