Methods We reported a case of PXA located in the cerebellum of a young adult in view of its extremely unusual location. Morphologic observation, immunohistochemical staining using DAKO EnVision system , histochemical stains including hematoxylin eosin and Gordon Sweet's reticulin methods were used.
