DIAGNOSTIC ELECTRON MICROSCOPY AND RENAL PATHOLOGY FOR RESIDENTS IN PATHOLOGY. THESE ARE USEFUL DIAGNOSTIC LESIONS RECOGNIZED BY HIGH RESOLUTION LIGHT MICROSCOPY (HRLM) AND ELECTRON MICROSCOPY (TEM) IN SURGICAL PATHOLOGY. THE LESIONS ARE REPRESENTATIVE OF DISEASES WHERE HRLM-TEM MAY BE NECESSARY FOR THE MORPHOLOGIC DIAGNOSIS. IT INCLUDES RENAL PATHOLOGY WHERE HRLM AND TEM STUDIES ARE NECESSARY FOR ACCURATE DIAGNOSIS.  THE COMPLETION OF THIS ACTIVITY WILL BE CREDITED TO YOUR ROTATION IN DIAGNOSTIC ELECTRON MICROSCOPY AND RENAL PATHOLOGY.  PRESENTATIONS: GROUPS OF PHOTOGRAPHS LABELED WITH LETTERS (A-T) WILL BE PRESENTED IN THIS POSTER. A NUMBERED LIST WITH DIAGNOSIS WILL BE ALSO POSTED (1-20). Tray to identify the lesions in the groups of photographs with letters and match them with the most likely diagnosis listed with numbers.  FILL UP THE ANSWERS FORM WITHIN THE ALLOTTED TIME AND RETURN IT TO THE EM LAB. THE POSTERS WILL STAY FOR ABOUT 3 MONTHS. THE ANSWERS WILL BE POSTED DURING THE LAST MONTH. ALL CASES ARE  AVAILABLE  AT:   http://www.lsuhsc.edu/no/schools/ms/departments/pathology/pathist/HRLM_TEM/ HRLMTEMcases/Tcasesindex.htm
