Nested stromal-epithelial tumours (NSETs) of the liver have been reported to be extremely unusual primary hepatic neoplasms. To date, few cases have been described in the literature. NSETs have been defined as non-hepatocytic and non-biliary tumours of the liver consisting of nests of epithelial and spindled cells, myofibroblastic stroma and variable intralesional calcification and ossification. Here, we report a case of a young female who underwent liver resection for a large hepatic lesion that proved to be a calcifying NSET on pathological examination. Details about the clinical and histopathological features of the tumour are reported.
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.
