Psammocarcinoma is a rare low-grade serous carcinoma arising either from ovary or peritoneum and is characterized by extensive psammomatous calcifications and invasion of surrounding structures. Prognostically, psammocarcinoma resembles borderline serous tumor and has a much more favorable outcome than the common serous carcinoma of ovary and peritoneum.
Keywords: borderline serous tumor; ovary; peritoneum; prognosis; psammocarcinoma.
