ya...psammoma body is correct...It is formed by progressive accumulation of calcium creating lamellated configurations..they are called so because of their resemblance to grains of sand.... i was surprised too coz what classic teaching tells is its found in papillary cystadenocarcinoma ovary, papillary carcinoma thyroid, meningioma...recently i came to know that its also found in somatostatinoma and mature ovarian teratoma...and in the pic the psammoma body is present in choroid plexus...
