Endometriosis of the appendix

Abstract

The clinical and pathological features of 6 cases of appendiceal endometriosis are reported. The appendix alone was involved in 3. Thefindings have been compared with previously reported cases. One of the largest deposits caused intussusception but otherwise the microscopic size of deposits did not correlate with symptomatology. The diagnosis may be suspected when the abdominalpain does not shvt from theperi-umbilical region to the right iliac fossa in the manner of classic appendicitis and when the symptoms begin during or are exacerbated by menstruation.

Acute appendicitis caused by endometriosis: a case report

“…The mucosa is not involved, but Langman et al . [33] found that the submucosa was involved in one-third of patients with endometriosis of the appendix. In their series, the endometriotic foci were also found in the muscle, serosa and subserosa.…”

“…In their series, the endometriotic foci were also found in the muscle, serosa and subserosa. There was no correlation between the location of the endometriotic foci and the patients' symptoms [33]. Therefore, mucosal or submucosal endometriosis is much more likely to mimic primary inflammatory diseases such as Crohn's disease, infectious or ischemic enteritis or colitis, or mucosal prolapse than endometriosis of the outer bowel wall [31].…”

Endometriosis and the appendix: a case series and comprehensive review of the literature

“…All studies reported either the general female population or a subgroup with endometriosis and patients with endometriosis of the appendix (Table 3) (31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49). There were 332 patients with endometriosis of the appendix at surgery or pathologic examination out of 8,198 women with endometriosis, yielding a prevalence of 2.8%.…”

Appendicular intussusception into a polyp

“…The aetiology of appendicular intussusception can be broadly divided into anatomical and pathophysiological, as described by Rudek et al [4] and Langman et al [5]. Anatomical intussusception is characterised by the presence of an appendix originating directly from the bottom of the caecal pole.…”
