Hypercalcemia Associated With Primary Mucinous Ovarian Tumor Followed By Pseudomyxoma Peritonei Can Be Fatal: A Case Report

Hypercalcemia is a common complication of malignancy, occurring in up to 30% of patients. The development of hypercalcemia in patients with cancer portends a worse prognosis, with patients more likely to have advanced disease and decreased survival rates. Mucinous neoplasms of the ovary account for 10%-15% of ovarian neoplasms. They may be benign, borderline, or malignant. The majority are benign or borderline, accounting for 80% and 16%-17%, respectively. Pseudomyxoma peritonei (PMP) is a rare disease. It refers that PMP is the accumulation of mucin in the abdominal or pelvic cavity derived from associated mucinous tumor usually from the appendix, but also associated with ovarian mucinous tumors. Herein, we report a case of hypercalcemia associated with primary mucinous ovarian tumor followed by PMP that had fatal consequences.
