Nested stromal epithelial tumor of the liver: A multidisciplinary approach to the treatment of an extremely rare malignancy.

Nested stromal epithelial tumor (NSET) of the liver is an extremely rare and unusual liver neoplasm with limited evidence of best practice for management. We report a 28-year-old male with NSET managed with primary partial hepatectomy with subsequent disease recurrence with follow-up metastectomy and successful radiofrequency ablation (RFA). Management of NSET of the liver requires a multidisciplinary approach. RFA proves beneficial in a patient with disease recurrence following tumor resection. In order to validate the regular use of RFA, more long term studies would be required.
