Stomach - Carcinoid Tumor with EUS
Comments: This is a 77 year old male who presents with occult gastrointestinal bleeding and anemia.
The upper GI endoscopy demonstrates a focal friable mass in the proximal stomach. Retroflexed views of the stomach reveal a generally atrophic mucosa without evidence of additional lesions. Close-up view of the mass reveals that it is friable and firm, but easily biopsied.
High-frequency ultrasound is performed of the lesion using water in the stomach as the medium. The high-frequency probe is placed directly adjacent to the mass lesion to determine the depth of penetration. We can see a focal, hypoechoic, infiltration just below the mucosa. It infiltrates into the submucosa, but there is no involvement of the muscularis propria.
Biopsies demonstrate nests of small cells consistent with a carcinoid lesion.
