Appendicitis

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Area of Science:

Gastroenterology
Gynecology
Surgical Pathology

Background:

Sigmoidorectal endometriosis comprises 70% of intestinal endometriosis cases.
Symptoms are often non-specific and can resemble colorectal adenocarcinoma.

Observation:

A 45-year-old woman presented with recurrent rectal bleeding.
Colonoscopy revealed a rectal polypoid mass, leading to anterior rectosigmoidectomy.

Findings:

Histological examination confirmed rectal endometriosis.
The resected specimen showed lymph node involvement, including epicolic lymph nodes.

Implications:

Lymphatic infiltration in endometriosis challenges its classification as a purely benign condition.
This finding necessitates careful consideration in differential diagnosis of rectal masses.
