psammoma การใช้

• Histologically, meningioma cells are relatively uniform, with a tendency to encircle one another, forming whorls and psammoma bodies ( laminated calcific concretions ).
• These are calcified remnants of papillary structures, and thus if a psammoma body is present anywhere within the tumor ( in the correct location ), then NIFTP cannot be diagnosed.
• Histopathologically, uterine serous carcinomas is typically characterized by ( 1 ) nipple-shaped structures ( papillae ) with fibrovascular cores ( 2 ) marked nuclear atypia ( irregularies in the nuclear membrane, enlarged nuclear size ), ( 3 ) psammoma bodies and ( 4 ) cilia.
