Pathologic Staging (AJCC 8th Edition)
Refractory epigastric pain and gastric outlet obstruction secondary to a large, locally advanced neoplastic mass in the distal stomach with extensive regional lymph node involvement, with superficial biopsies confirming at least high-grade dysplasia consistent with intramucosal adenocarcinoma (diagnosed by previous biopsy at our lab: Pathology number 1529-26.
Three containers were received.
1 Designated as near total stomach with omentum: Stomach measured 10.5 cm along the greater curvature and 5.5 cm along the lesser curvature, with a proximal circumference of 5 cm and a distal circumference of 2.5 cm. Attached was a greater omentum measuring 40 x 22 x 1.5 cm and an additional fatty tissue measuring 11 x 8 cm. Opening of the stomach revealed an ulcerated, solid, firm, creamy-colored mass measuring 8.5 x 6 cm (depth) . The mass infiltrated the full thickness of the gastric wall. The lesion is located 6 cm from the proximal resection margin and 0.8 cm from the distal resection margin. A total of 13 lymph nodes were dissected from the lesser and greater curvatures, the largest measuring 2.5 cm. The omentum showed four rubbery areas/masses, the largest measuring 1 cm.
2 Disintegrated as small mass?? lymph node from side of colon: soft tissue piece measuring 1.7 x 1.3 x1 cm, totally embedded.
3 Designated as fluid from abdomen (saline wash): 10ml fluid, for cytological examination, one smear was prepared and stained.
