ABSTRACT

Background: Asymptomatic patients at average risk of developing colorectal cancer are encouraged to undergo screening colonoscopy beginning at age 45 years. While ileal intubation is often considered the gold standard for a complete colonoscopy, the relatively low diagnostic yield has prevented widespread adoption. Small bowel cancers, including neuroendocrine tumors, may present incidentally as terminal ileitis on routine colonoscopy with terminal ileum intubation. Neuroendocrine tumors, the most common primary neoplasm of the small intestine, are often asymptomatic or present as nonspecific abdominal pain in the sixth or seventh decade of life. Case Report: A 51-year-old asymptomatic male with unremarkable physical examination underwent screening colonoscopy that revealed scattered ulcerations of the terminal ileum. Immunohistochemistry of the lesion was consistent with well-differentiated neuroendocrine tumor, World Health Organization Grade I. DOTATATE positron emission tomography/computed tomography demonstrated avid adjacent right mesenteric lymph node and avid focal pancreatic body lesion. Fine-needle biopsy and immunohistochemistry of the pancreatic lesion confirmed neuroendocrine tumor, while the mesenteric lymph node was found to be benign. The patient underwent robotic-assisted ileocolic resection and has ongoing surveillance of the pancreatic lesion. Conclusion: Terminal ileitis encompasses a host of pathologic processes, including inflammatory states, infectious disease, malignancy, and vasculitis. Importantly, small bowel cancer is an increasing cause of terminal ileitis. Screening colonoscopy with ileal intubation can be a valuable tool for early detection of these lesions.

ABSTRACT

BACKGROUND: Renal cell carcinoma (RCC) is responsible for nearly 13,000 deaths in the United States every year, predominantly because of metastasis to other bodily organs. However, metastasis of RCC to the stomach occurs rarely; it presents as solitary or multiple polyps or as ulcers concerning for primary gastric carcinoma. Bleeding from metastasis to the stomach is a rare and underrecognized cause of gastrointestinal bleeding. We describe a case of gastrointestinal bleeding in an elderly female who was found to have a gastric polyp of RCC origin. CASE REPORT: An 83-year-old female presented to our hospital for evaluation of an acute right basal ganglia hemorrhage after falling at her nursing home. Her hospital course was notable for melenic stool and anemia. Upper endoscopy revealed a single 40-mm pedunculated polyp and active bleeding on the lesser curvature of the stomach. Polypectomy and clipping were performed. Pathology was consistent with metastatic clear cell RCC. The patient's family declined a referral to oncology for evaluation of the newly diagnosed malignancy and opted for hospice care. CONCLUSION: This case illustrates the potential for metastatic RCC to involve the stomach and cause gastrointestinal bleeding and anemia. The case also illustrates the role of upper gastrointestinal endoscopy in diagnosing and treating metastatic causes of gastrointestinal bleeding.

ABSTRACT

OBJECTIVE: To identify potential risk factors for developing congenital nasolacrimal duct obstruction (CNLDO). STUDY DESIGN AND METHODS: A cross-sectional study. A quantitative questionnaire was distributed to a sample of mothers attending the Pediatrics Clinic at King Khalid University Hospital, Riyadh, Saudi Arabia. RESULTS: A total of 756 mothers responded to our questionnaire. Of the 756 filled questionnaires, 389 (51.67%) were male children. 5.3% of the mothers lived in non-urban settings. CNLDO was reported in the children attending the clinic by 17.1% (129/756) of their mothers. Average age (±SD) of infants when persistent tearing was noticed was 3.2 ± 2.7 months, while average age (±SD) of resolution was 9.6 ± 3.7 months. Of the children with CNLDO, 37.2% (48/129) still have persistent tearing at the time of distributing the questionnaire. Among the group with CNLDO, 17% (22/129) of their mothers have experienced an infection during pregnancy (p = 0.022). Within the same group, 14.7% (19/129) of the affected children were reported by their mothers to have other children with CNLDO which was statistically significant (p = <0.001). CONCLUSION: CNLDO could have a genetic predisposition and maternal infection is a possible risk factor for developing CNLDO. Surgical management awareness should be emphasized to relieve children from this relatively common and benign condition.
