Core Tip

Core Tip: Retroperitoneal cysts are rare and usually asymptomatic abdominal lesions. Epidermoid cysts are frequent benign cutaneous tumors, but retroperitoneal localization of these cysts does not occur very often. Surgery is the gold standard for the diagnosis and treatment of retroperitoneal epidermoid cysts. Epidermoid cysts around the pancreas are easily misdiagnosed as cystic solid pseudopapillary tumors of the pancreas (SPTPs). Because of the different biological characteristics of retroperitoneal epidermoid cysts and SPTPs and the different surgical methods used for their treatment, surgeons should pay particular attention to preoperative diagnosis to reduce severe surgical complications and improve the quality of life of patients.
