Elemental composition of calcification in breast pathology. (A) Microcalcifications (arrow) in BLm (fibroadenoma). (B) Electron micrograph by TEM of the microcalcification indicated in (A). (C) EDX spectra obtained by microanalysis of commercial standard sample utilized as a control. (D) EDX spectrum revealed that microcalcifications were composed of calcium oxalate (CO). (E) Microcalcifications (arrow) in an ISCm (comedocarcinoma). (F) Electron micrograph by TEM of the microcalcification indicated in (E). (G) EDX spectra obtained by microanalysis of commercial standard sample utilized as a control. (H) EDX spectrum revealed that this microcalcification was composed of magnesium-substituted hydroxyapatite (Mg-Hap). (I) Microcalcification type related to breast pathology by statistical analysis.
