Extensive medlar search showed presence of only 28 cases of psammocarcinoma of ovary reported till date. Nanobacteria promote crystallization of psammoma bodies in ovarian cancer Archebacteria such as nanobacteria are, for example, involved in kidney stone formation. Introduction Psammocarcinoma of ovary is a rare serous neoplasm characterized by extensive formation of psammoma bodies, invasion of ovarian stroma, peritoneum or intraperitoneal viscera, and moderate cytological atypia. The presence of psammoma bodies had different significances in various studies, while in some the prognostic has been better [17,18] in other they didn’t have a prognosis significance [].

The present study provides evidence for a causative link between the presence of nanobacterial infections and the development of psammoma bodies in ovarian adenocarcinomas. We therefore retrospectively investigated the radiological and histopathological evidence of calcifications in 44 cases of ovarian mucinous cystic tumors (22 benign, 13 borderline, and 9 malignant) and 21 cases of ovarian serous cystic tumors (6 benign and 15 malignant) in which a non-contrast CT scan was performed.

Serous psammocarcinoma is a rare variant of serous carcinoma arising from either ovary or peritoneum, characterized by massive psammoma body formation, low grade cytologic features, and invasiveness. 1994 Feb;29(2):100-2, 125. MR-guided focused ultrasound surgery, present and future. b PBs in fibrocytes (thick arrow), c PBs in cancer cells (thick arrow). Intramural calcifications were frequent in benign tumors, and intra-cystic calcifications were frequent in proliferating tumors. BACKGROUND. However, their etiology and prognostic significance remain obscure. This article related to pathology is a stub. No psammoma bodies does not automatically mean there is a cancer.
