A carcinoid tumor caused appendiceal obstruction and inflammation in a healthy man. Surgery and microscopy confirmed the diagnosis after initial symptoms resolved.

Area of Science:

  • Gastroenterology
  • Oncology
  • Surgical Pathology

Background:

  • Appendiceal carcinoid tumors are rare, often presenting with nonspecific symptoms.
  • Early diagnosis is crucial for effective management and preventing complications.

Observation:

  • A previously healthy male presented with acute right lower quadrant abdominal pain, anorexia, constipation, and pyrexia.
  • Initial presentation mimicked typical appendicitis but lacked leukocytosis, with an elevated erythrocyte sedimentation rate.
  • Ultrasound revealed a persistently dilated appendix despite symptom resolution.

Findings:

  • Microscopic examination post-surgery confirmed a carcinoid tumor obstructing the appendiceal lumen.
  • The tumor led to secondary inflammation and dilatation of the appendix.

Implications:

  • This case highlights the importance of considering rare appendiceal pathologies, like carcinoid tumors, in the differential diagnosis of abdominal pain.
  • Persistent imaging findings, even with resolving symptoms, necessitate further investigation, including surgical exploration.
  • Accurate diagnosis through surgical pathology is essential for appropriate patient management.
