Ruptured appendiceal cystadenoma presenting as right inguinal hernia in a patient with left colon cancer: A case report and review of literature

Abstract

Background: Mucoceles resulting from cystadenomas of the appendix are uncommon. Although rare, rupture of the mucoceles can occur with or without causing any abdominal complaint. There are several reports associating colonic malignancy with cystadenomas of the appendix. Herein, we report an unusual and interesting case of right inguinal hernia associated with left colon cancer.

Adenocarcinoma of the Appendix Is Rarely Detected by Colonoscopy

“…16 Lee et al first described their abnormal colonoscopy findings in a patient with pseudomyxoma peritonei. 22 We are unaware of a large series that adequately describes the preoperative colonoscopic findings in patients presenting with appendiceal adenocarcinoma with pseudomyxoma peritonei. Thus, the aim of this study was to determine the diagnostic yield of colonoscopy in detecting previously diagnosed appendiceal adenocarcinoma with pseudomyxoma peritonei and to characterize the mucosal abnormalities associated with appendiceal adenocarcinoma with pseudomyxoma peritonei.…”

Unusual contents of a scrotal swelling

“…In 16 of the patients, a laparotomy was performed following the identification of mucin with a variety of additional procedures. A detailed review of the literature identified only two cases, such as ours, in which atypical features of the hernia together with vague gastrointestinal symptoms lead to preoperative evaluation and diagnosis of pseudomyxoma peritonei 7 8…”

An Appendiceal Carcinoid Tumor within an Amyand’s Hernia Mimicking an Incarcerated Inguinal Hernia

“…Salemis et al [14] reported an appendiceal villous adenoma, while there are also only a few cases of cystadenomas of the appendix [15, 16]. Moreover, appendiceal adenocarcinomas within an Amyand's hernia are rarely observed [4, 5].…”
