Case of the Month

This program offers one challenging case 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 29-year-old woman presents with a complaint of abdominal fullness. An adnexal mass is noted on pelvic examination. Imaging reveals a 12.0-cm solid mass in the left ovary, as well as a few abnormal-appearing regional lymph nodes. The patient undergoes left salpingo-oophorectomy with para-aortic lymph node dissection. Grossly, the ovary is solid, with focal nodules on the external surface and a fleshy, tan, lobulated cut surface.
