Summary
Gastric carcinoids, rare endocrine tumors, present diverse radiographic features making diagnosis challenging. This report details three cases, highlighting associations with pernicious anemia and adenocarcinoma.
Area of Science:
- Gastroenterology
- Endocrinology
- Oncology
Background:
- Carcinoids are endocrine tumors originating from enterochromaffin cells, predominantly found in the gastrointestinal tract (over 80%).
- Gastric carcinoids represent a rare subset, accounting for only 2-3% of all carcinoid tumors.
- The diverse and often subtle radiographic presentations of gastric carcinoids complicate their accurate diagnosis.
Observation:
- This study presents three distinct cases of gastric carcinoid tumors.
- One case involved a patient with pernicious anemia, a known association with gastric carcinoids.
- Another patient exhibited a rare co-occurrence of gastric adenocarcinoma and a stalked gastric carcinoid.
Findings:
- Gastric carcinoids are rare tumors with varied imaging findings, including intramural defects, polyps, ulcers, and intraluminal lesions.
- The association between gastric carcinoids and pernicious anemia is noted.
- Simultaneous occurrence of gastric adenocarcinoma and carcinoid is an unusual finding.
Implications:
- Increased awareness of the varied radiographic features is crucial for early detection of gastric carcinoids.
- Recognizing potential associations with pernicious anemia can aid in diagnosis.
- The co-existence of adenocarcinoma and carcinoid highlights the complexity of gastric neoplasms and may influence treatment strategies.
