Appendiceal carcinoid tumor in children: implications for less radical surgery?

The discovery of an appendiceal carcinoid tumor found incidentally or during the course of diagnostic or therapeutic procedures is a burden to both the patient and clinician. The role of the correct surgical operation is paramount for lesions suspected to be malignant. In the pediatric population, appendiceal carcinoids continue to challenge the clinician in choosing the optimal treatment when lesions are larger than 2 cm or involve the appendical base. While the criteria used to define these distinct lesions are available in most cases, the management and treatment are still debated and controversial when considering more radical surgical intervention. The purpose of this article is to give an overview regarding the history, diagnosis, histopathology, management, and controversies associated with appendiceal carcinoid in the pediatric population.
