✦ Synopsis

This, to the best of our knowledge, is thefirst report of the cytological observation of psammoma bodies in an endometrioma. Psammoma bodies are laminated, calciJied spherites, commonly associated with meningiomas, ovarian serous cystadenocarcinomas, and papillary carcinoma of the thyroid. Many other pathologic processes can produce dystrophic calcijication in the form ofpsammoma bodies. The physiopathological theories of the origin of dystrophic calcification and psammoma bodies will be discussed. The most promising theory implicates matrix vesicles as the nidus for calcification.

Psammoma body is a rare finding in a cervicovaginal smear and can be associated with either benign or malignant diseases. Here we report a case to illustrate the association of psammoma bodies with benign granulomatous reactions to a foreign material (aluminum silicate).

## Abstract Psammoma bodies (PBs) form an important diagnostic criterion of papillary thyroid carcinoma (PTC), but their mechanism of formation is not clear. Following our observation in a case of PTC that laminated hyaline globules may be the precursor form of PBs, the present study was undertaken
