AIM: The study was conducted to delineate the histological problems in diagnosing uterine @entity361 in morcellated material. METHODS: All cases of morcellated uteri performed between 2008 and 2014 were reviewed. The incidence of unexpected @entity5 , defined as any @entity5 with a clear-cut diagnosis of @entity1822 ( @entity1822 ) or @entity6019 ( @entity6019 ), was noted. Cases with absolute discrepancy between the diagnosis of the morcellated @entity5 and the subsequent diagnosis were also included in the study. RESULTS: Out of 631 cases, a final diagnosis of @entity1822 or @entity6019 was made regarding three and five @entity5 , respectively. @entity1 age ranged from 25 to 48 years. Two further cases initially diagnosed as @entity6019 proved to be endometrial stromal nodules with smooth muscle differentiation. Two cases were diagnosed as smooth @entity11090 with uncertain malignant potential and the @entity1 remain free of disease. One @entity5 was diagnosed as an @entity1204 and proved to be benign and finally a @entity2909 variant presented with presumed @entity6378 . CONCLUSION: Both endometrial stromal and smooth @entity11090 with malignant behavior can be encountered at a young age. Because of the limitations in histological evaluation, morcellated @entity5 may be overdiagnosed or underdiagnosed by pathologists.
