calcospherite

 [kal″ko-sfēr´īt]
one of the minute globular bodies formed during calcification by chemical union of calcium particles and albuminous matter of cells.

cal·co·sphe·rite

(kal'kō-sfēr'īt),
A tiny, spheroidal, concentrically laminated body containing accretive deposits of calcium salts; found most frequently in papillary carcinoma of the thyroid and ovary, and in meningioma, probably as the result of degenerative changes in the fibrovascular stroma.
Synonym(s): psammoma bodies (3)

Ganglioglioma often presents radiologically as a mural nodule within a cyst and exhibits several helpful diagnostic features, including higher cellularity, dysmorphic or binucleate neurons unassociated with pink cells, pilocytic morphology of the glial component, calcospherites, desmoplasia, and perivascular lymphocytic infiltrates.
Many of Wagge's conclusions were formed by Iris earlier experiments (Wagge 1951) that showed migrating epithelial cells were responsible for secretion of both the organic membranes and the crystals of calcium carbonate within the calcospherites (conchiolin compartments).
Microscopically, malakoplakia is characterized by aggregates of histiocytes, the Von Hanseman cells, with Michaelis-Gutmann calcospherites.
Previous reports of fine-needle aspiration of dermoid cysts from other sites have demonstrated various cytologic findings, including nucleated and anucleated squamous cells, hair, keratinous debris, cholesterol, calcospherites (calcium deposits), and inflammatory cells.
