“…Embryologically, the epithelium of the ovary and the mesothelium of the peritoneum have the same origin, but PPP is rarer than ovarian psammocarcinoma. To date fewer than 30 cases of peritoneal psammocarcinoma have been reported in the literature …”

[1][2][3][4][5][6][7][8][9] These tumors are characterized by extensive psammoma body formation, invasion of the surrounding structures and low-grade cytological atypia. Unlike usual serous carcinomas, primary peritoneal psammocarcinoma (PPP) involves advanced peritoneal involvement without gross involvement of the ovaries.…”

“…Sanguedolce et al [3], Riboni et al [4], and Zakkouri et al [5] have since added 3 more cases of ovarian psammocarcinoma. Thirty PPP tumors originating from the peritoneum have been described [6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]. According to these reports, PPP usually exhibits as a small peritoneal tumor, except for a few rare cases in which a large pelvic tumor was observed [10,14].…”

Psammocarcinoma is a serous peritoneal tumor arising from the ovary or the peritoneum and characterized by low-grade nuclear features, extensive psammoma bodies, and invasiveness. Only 62 cases have ever been documented, 30 primary peritoneal and 32 primary ovarian, most of which presented as small tumors. Adjuvant therapies, including chemotherapy and radiation, were performed in 12 of the primary peritoneal cases, without any clear evidence of benefit. We present a case of an unusually large primary peritoneal psammocarcinoma with unexpected outcome. The patient was a 38-year-old woman with a tumor of the peritoneum which adhered densely to the uterus and rectum and developed into the intra-abdominal cavity and retroperitoneal space. After adhesiolysis of the tumor and rectum, suboptimal surgical reduction left a 4 cm × 2 cm tumor segment. Postoperative chemotherapy, consisting of paclitaxel and carboplatin (TC) for 1 course, and cyclophosphamide and cisplatin (CP) for 5 courses, was conducted. The residual tumor responded completely to the chemotherapy and the patient is alive today, with no evidence of disease 15 months after the surgery. Our case implies that CP therapy is a potential regimen of postoperative remission-induction therapy for suboptimally resected primary peritoneal psammocarcinoma.

Case Report: Fortuitous discovery of primary peritoneal psammocarcinoma

Psammocarcinoma is an uncommon subtype of low-grade serous carcinoma. It is characterized by the presence of extensive psammoma bodies and can have either an ovarian or peritoneal origin. To our knowledge fewer than 30 cases of primary peritoneal psammocarcinoma (PPP) have been reported in the English literature. We report a rare case of PPP in a 74-year-old female, discovered fortuitously within a laparotomy for gallbladder lithiasis. At laparotomy, multiple nodular implants involving the omentum, the peritoneum and a magma of intestinal loops in the right iliac fossa were noted. A biopsy from nodules was performed. Gross examination showed multiple nodules of different sizes in the fat tissue. Pathologic examination showed massive psammoma bodies representing more than 75% of the tumor. The final diagnosis was psammocarcinoma. Our patient was referred to the gynecologic department for further investigation and to ascertain whether the tumor arose from the ovaries or peritoneum. Hysterectomy, bilateral adnexectomy and omentectomy were performed. Macroscopic examination showed that both ovaries were intact having a normal size. No invasion of ovarian stroma was shown in microscopic examination. The patient died of SARS-CoV-2 (COVID-19) six days after the surgery. PPP is a rare type of low-grade serous carcinoma. The behavior of this tumor is unclear, and the treatment is not standardized because of its rarity and lack of long-term follow-up. More cases need to be studied for better understanding and improvement of the management protocols.
