Highlights • PRMCs are very rare and they share macroscopical and histological similarity to ovarian cystadenomas. • It is important to rule out Echinococcosis specially in endemic regions such as South America. • Complete surgical excision of the PRMCs is recommended to eliminate the risk of infection, recurrence and malignant degeneration. • It is important to remember that cystic fluid spillage has to be prevented due to the uncertain pathology of the tumor in most of the cases.
Mucinous cystadenomas and carcinomas of the ovary are well-established and common tumors. However, Primary retroperitoneal mucinous cystadenomas (PRMCs) are very rare. We present a 50-year-old woman referred to our institution with history of intermittent abdominal pain and palpable mass in her left flank. On CT-scan an unilocular cystic mass with thin wall measuring 171 × 155 × 108 mm in the retroperitoneum was shown. Patient underwent surgical excision of the tumor. The histopathology examination showed a cystic mass with a fibrous wall and an epithelium composed of a single layer of columnar cells with mucin vacuoles compatible with PRMC.
