Core Tip

Core tip: Rare cases of hepatic nested stromal-epithelial tumours (NSETs), consisting of non-hepatocytic mixed stromal and epithelial neoplasms with associated calcification and ossification, have been previously described. To date, NSETs’ behaviour and prognosis are completely unclear. We report the case of a 23-year-old female who underwent liver resection for a large hepatic, calcifying NSET. Details about preoperative imaging and the clinical and histopathological features of this very rare hepatic tumour are reported.
