title: ["Fibrous long-spacing collagen" in seminomas].
abstract: In the lymphocytically infiltrated stroma of 2 out of 5 classic seminomas normal collagen, an amorphous substance and a collagen with atypical periodicity, so called fibrous long spacing collagen, were found. In one case, the fibrous long spacing collagen was in contact with the basal membrane of tumor cells. The origin and the importance of fibrous long spacing collagen are discussed.
