This program offers at least two challenging cases each month from the CAP Performance Improvement Program in Surgical Pathology. For each case, you will use a virtual microscope whole slide image of a surgical specimen to diagnose diseases.
You will be presented with information on each case including: specimen source, clinical history, laboratory findings, and a representative whole slide image of the surgical specimen. After you complete each case, you will receive a case summary with three multiple-choice questions that relate to the case.

A 27-year-old man presents with recent onset of abdominal pain. A computed tomography scan demonstrates an abdominal mass with multiple satellite nodules. A biopsy of the abdominal mass is performed, revealing a cellular undifferentiated tumor. Immunohistochemical studies reveal the tumor to be positive for cytokeratin AE1/AE3, focally positive for desmin in a paranuclear dot-like pattern, and positive for nuclear expression WT1 (using antibodies to the C-terminus).
