[Diagnostic use of the cell culture technique in a case of postoperative saccate lymphorrhea].

The Authors demonstrated the presence of tumour cells by an in vitro culture of the cells from the pellet of a postoperative saccate effusion, when no tumor cells were evident by the cytologic examination of the effusion. The ultrastructural features and the immunocytochemical characteristics of the cell line were analyzed and these data confirmed its malignant nature. It allowed a firm diagnosis, a correct therapy and prognosis.

[Ultrastructural and immunoelectron microscopic study of the desmoplastic stroma in carcinoma of the breast].

Different collagen types (I, III, IV, V) were identified in breast carcinoma desmoplastic tissue by ultrastructural analysis and immunoelectronmicroscopy. Type V collagen is present as a 12 nm. fibril in the stroma, either adjacent to the basement membrane or concentrated around the thicker fibers. Myofibroblasts, fibroblasts and tumor cells can be its major producers. Its possible function as a bridge between different collagens can be utilized, with different finality, by the same cells that have produced it. Furthermore, type V collagen can be involved in tumor invasion of the stroma and in all directional movements of tumor cells, as already demonstrated for other extracellular matrix components.
