Collagen types I, III and IV and procollagen III peptide (P III P) were examined immunohistochemically in 38 papillary carcinomas of the thyroid. The immunoreactivity to both type I and type III collagen was diffuse and abundantly observed in the fibrous stroma, where it displayed a fibrillar and/or granular pattern with little difference in the intensity of the staining. The immunoreactivity to collagen type IV was localized in the basement membrane of the vessels and partly in the tumor cell nests. A distinctive cytoplasmic immunoreactivity to P III P was observed in the cancer cells and the fibroblasts in all of the 38 papillary carcinomas, specifically an intense and extensive immunoreactivity by the cancer cells present in tumors having fibrosclerosing stroma and/or showing an extensive local invasion. Thus, it is conceivable that stromal collagen in a papillary carcinoma can be produced by not only the fibroblasts but also by tumor cells and its productivity could be affected by the degree of the tumoral invasion.
