Morphology of Nanocrystaline Calcifications of Ovarian Tumors

Abstract

This paper is devoted to morphology, microstructure, phase and elemental composition of pathological crystalline inclusions in malignant ovarian neoplasms. It was found that pathological minerals are represented by calcium apatite with different levels of crystallinity. The transmission electron microscopy in combination with electron microdiffraction has shown some structural and morphological features of ovarian apatite crystals, which were not detected by other methods. According to transmission electron microscopy, the crystalline particles of calcifications are polydisperse (of different sizes) and the range of their sizes can be quite large.
