[Ultrastructural analysis of amyloid deposits in pleomorphic adenoma of the salivary glands by topo-optical studies].

Abstract

It is well established that the stroma of some tumours contains amyloid. Authors have studied in pleomorphic tumours the occurrence of amyloid. Out of 40 salivary gland tumours 5 contained amyloid in their stroma between tumour-cell cords. Amyloid of salivary gland tumours had a resistant structure. The possible pathomechanisms of amyloid deposition are discussed.
