Carcinoid tumors of appendix presenting as acute appendicitis
1Department of General Surgery, İnönü University Faculty of Medicine, Malatya-Turkey.
Summary
Appendiceal carcinoid tumors are rare findings during appendectomy for acute appendicitis. These tumors, when small and non-perforated, have an excellent prognosis with no recurrences observed in this study.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Oncology
Background:
- Appendiceal carcinoid tumors are rare and often asymptomatic.
- They are typically discovered incidentally during histopathological examination after appendectomy for acute appendicitis.
Purpose of the Study:
- To present data on patients who underwent appendectomy for acute appendicitis and were incidentally found to have carcinoid tumors.
- To analyze the characteristics and outcomes of appendiceal carcinoid tumors.
Main Methods:
- Retrospective analysis of patient charts from January 1999 to September 2018.
- Inclusion of patients who underwent appendectomy for acute appendicitis and were diagnosed with carcinoid tumors.
Main Results:
- 12 out of 2778 appendectomies (0.43%) revealed carcinoid tumors.
- The median tumor size was 0.7 cm, with no perforations detected.
- Most patients (11/12) underwent appendectomy; one had a right hemicolectomy. No recurrences were observed during a median follow-up of 41.5 months.
Conclusions:
- Appendix carcinoid tumors are rare, usually asymptomatic, and diagnosed incidentally.
- Treatment and prognosis depend on tumor size, invasion, and mitotic rate.
- The prognosis is excellent for non-perforated tumors, emphasizing the importance of histopathological review.

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...

2.2K
We describe a protocol for the production, culture, and visualization of human cancers, which have metastasized to the peritoneal surfaces. Resected tumor specimens are cut using a vibratome and cultured on permeable inserts for increased oxygenation and viability, followed by imaging and downstream analyses using confocal microscopy and flow...

The protocol describes a method for creating a patient-derived colorectal cancer (CRC) organoid model co-cultured with tumor-infiltrating lymphocytes (TILs) to study their interactions and therapeutic potential. This model provides a preclinical platform to explore immune responses in the tumor microenvironment and to predict the efficacy of TIL-based therapy for personalized CRC...
