Full Text: To the Editor.--It was brought to our attention that there is an error in the table of our recently published Resident Short Review article in the August 2008 issue of the Archives (Gopal P, Parker JR, Debski R, Parker JC Jr. Choroid plexus carcinoma. Arch Pathol Lab Med. 2008;132[8]:13501354). The table states that atypical teratoid/rhabdoid tumor is negative for epithelial membrane antigen (EMA); however, this is incorrect in that most of these tumors stain with EMA. In addition, we have decided to modify the staining characteristics for CAM 5.2 and glial fibrillary acidic protein in papillary meningioma from negative to not applicable be cause these characteristics are not fully understood in papillary meningioma, specifically.

We also clarified the original table footnote to facilitate better understanding by readers. We apologize for any confusion. The revised table below reflects all of these changes.
