COURSE DESCRIPTION

This comprehensive approach to the gastrointestinal system is designed to educate general pathologists, junior GI pathologists and pathologists-in-training on problematic areas of common and unusual lesions, the newest guidelines and how they impact the diagnostic process, and practical approaches and tips to avoid diagnostic pitfalls. The structure of this course, divided along the GI anatomic landscape, allows the faculty to emphasize key diagnostic features of inflammatory, infectious and neoplastic pathology as encountered in biopsy and resection specimens. The cases are selected to assist in developing an appropriate differential with emphasis on how to navigate to the correct diagnosis. Supplementary cases and special studies will augment the discussion to present the full morphologic spectrum and show how to incorporate ancillary studies effectively. At the conclusion of the course, participants will be able to develop and work through the differential diagnostic possibilities and render the best possible diagnosis. This is USCAP mentoring at its best!

COURSE OBJECTIVES

  • Correctly classify dysplasia in Barrett esophagus, stomach and anus
  • Distinguish medication, infection and systemic disease involvement of the GI tract
  • Formulate a differential diagnosis for sprue-like lesions of the small bowel
  • Comprehend the proper classification of gastric and colonic polyps and mucinous appendiceal lesions
  • Evaluate the key features of colorectal staging

Case of the Month: May 2021

61 year old female presents to GI clinic with history of non-bloody, watery diarrhea that waxed and waned for years, but was more consistent in the past 4 months.

Case of the Month: April 2021

A 71-year-old female presented with dysphagia, intermittent left upper abdominal pain, and unintentional weight loss of approximately 7 lbs. over 4 months. (pdf link below)

Case

An abdominal CT scan with contrast demonstrated an 8.5 x 6.0 x 5.5 cm solid, well-marginated mass along the fundus of the stomach, extending to the gastroesophageal junction (Figure 1). Upper gastrointestinal endoscopy showed a large subepithelial gastric mass with no bleeding or ulceration of the mucosa located in the cardia/fundus of the stomach (Figure 2). EUS revealed a hypoechoic subepithelial gastric mass in the cardio-fundic region which appeared to originate from the muscle layer of the stomach wall. Fine needle aspiration and biopsy were performed (Figure 3) followed by a proximal gastrectomy. The gross photo and microscopic findings are shown below (Figure 4-5).

Abdominal CT scan demonstrating an 8.5 cm solid, well-marginated mass with non-homogeneous contrast enhancement along the fundus of the stomach extending to the gastroesophageal junction.

Endoscopic picture of intact gastric mucosa with bulging subepithelial mass in the cardia/fundus of the stomach visible on retroflexion view.

3A: FNA of submucosal lesion showing a few aggregates of cytologically bland spindle cells with myxoid background.

3B: Immunohistochemical stain for β-catenin shows strong and diffuse nuclear and cytoplasmic labeling in the tumor cells.

Cross section of the resected gastric mass reveals a well-demarcated intramural heterogenous mass with discrete contours. The overlying mucosa (upper portion of the picture) and the serosal surface (lower portion of the picture) are both intact. Esophageal-gastric junction is on the left side of the picture.

5A: High-power view of the central area of the lesion demonstrating a hypercellular storiform pattern of spindle cells with moderate nuclear pleomorphism and inconspicuous nucleoli.

Intermediate-power of hypocellular area from the periphery of the mass demonstrating spindle cells in a myxoid background containing dilated blood vessels with a staghorn pattern.

5C: Immunohistochemical stain for CD117 is negative.

5D: Immunohistochemical stain for β-catenin shows cytoplasmic and strong nuclear labeling in the tumor cells.
