INTRODUCTION: @entity2460 are rare soft tissue @entity5 of submesothelial origin and variable malignant potential. The most common localization is pleural, whereas only 0.6% are of extrapleural localization. @entity2460 of the peritoneum, especially of gastric serosa is an extremely rare form of this @entity5 . CASE REPORT: We presented a 65-year-old female @entity1 with @entity2460 of the @entity1819 . Histopathological analysis of removed tissue showed the presence of @entity5 tissue built of spindle cells, elongated nuclei with moderately abundant cytoplasm. Cells were in a noncohesive arrangement, in smaller areas distributed in the form of palisade. There were amounts of hipocellular connective tissue, hyalinised, with small foci of @entity730 . Mitoses were rare (less than 3/10 HPF). Blood vessels surrounded the connective tissue. Reviewed material did not contain elements of the parent organ. Immunohistochemically there were positivity on @entity2280 and @entity2277 , and negativity to S100, @entity11280 , @entity2467 , dezmin, and Ki-67 is < 2%. The change was diagnosed as a @entity2460 . CONCLUSION: Considering that benign solitary @entity5 of extrathoracic localizations are extremely rare @entity5 with unpredictable biological behavior and the possibility of recurrence, a long-term clinical and endoscopic follow-up on yearly basis of @entity1 with this disease is recommended.
