BACKGROUND Whereas testicular metastases are in themselves a rare entity, testicular secondaries from an appendiceal carcinoma have not yet been described. The case also illustrates the diagnostic dilemma of a tumour presenting as epididymo-orchitis. CASE PRESENTATION The authors present a case of an appendiceal carcinoma that, two years after radical therapy, manifested as a secondary in the...

Introduction: Small bowel obstruction due to an appendiceal mucocele is comparatively rare. Case Report: A rare case of a small bowel obstruction due to a mucocele of the appendix, which had been histopathologically diagnosed as a mucinous cystadenoma. Partial resection of the ileum and appendectomy through traditional laparotomy relieved the patient from abdominal pain and congestion from the ...

To cite: Rouzbahman M, Chetty R. J Clin Pathol 2014;67:193–197. ABSTRACT Mucinous lesions of the appendix and ovary are commonly encountered in routine practice. There are several published classification schemes for appendiceal mucinous neoplasms with resultant inconsistent use of terms and clinical doubt. While nomenclature is more settled with regards to ovarian mucinous neoplasms, the diffi...

We report the case of a 67-years-old male who presents colic abdominal pain located in the right lower quadrant for over 2 years. No more symptoms. Barium enema showed a large filling defect (narrow) in the medial wall of the cecum and this was thought to be the result of extrinsic compression by an appendiceal mass (Fig. 1). At colonoscopy, deep in the cecum, through the appendiceal orifice, a...

The appendix is a very common specimen in any pathology department because its disorders especially the benign ones are relatively common. Appendiceal diverticulitis can present acutely with a clinical picture resembling that of an acute appendicitis. This report is of two cases which were admitted to our hospital's Emergency Department with acute abdominal pain and in which reactive epithelium...

Pseudomyxoma peritonei (PMP) is a rare disease, caused by primary mucinous tumors that arise most frequently from appendix, ovary, or pancreas. Usually diagnosis is made by computed tomography, but ultrasonography can be a very useful imagistic method, if this diagnosis is taken into account by the observer. We present a case of a PMP caused by an appendiceal mucinous carcinoma, in a 34-year-ol...

PURPOSE Diverticulitis of vermiform appendix is known as a rare cause of acute appendicitis, most of which are diagnosed after surgery. We compared appendiceal diverticulitis with acute appendicitis to study the clinical characteristics of appendiceal diverticulitis. METHODS Among 1,029 patients who received appendectomy from January 2009 to May 2011, 38 patients with appendiceal diverticulit...

AIM To assess the clinicopathologic features and its relationship with prognosis of pseudomyxoma peritonei (PMP) in Chinese patients. METHODS The clinicopathologic features and follow-up data of 92 patients with PMP were reviewed and retrospectively analyzed. The cases were categorized into three groups: disseminated peritoneal adenomucinosis (DPAM), peritoneal mucinous carcinomatosis (PMCA),...

In this appendix, we state a number of preliminary results that will be used in the proofs of the four theorems in the main text. Detailed proofs of the results listed below may be found in Appendix C below. The proofs of the main results are given in Appendix B. The proof of Theorem 4.1 uses Lemmas A.1 and A.2 below. Theorems 5.1 and 5.2 use Lemmas A.3–A.12, A.14, A.15, Theorem A.2, and Lemmas...
