Appendiceal mucocele is an infrequent but well recognized entity that can present with a variety of clinical syndromes or can be asymptomatic and discovered incidentally. A 55 years old patient was admitted in the emergency department for acute right lower quadrant pain. A diagnosis of appendicitis was made. At operation an appendiceal mucocele was found. An appendectomy was performed. The diag...

Metastatic small bowel cancers are extremely rare in clinical practice. Primary appendiceal adenocarcinoma with gastrointestinal metastasis is seldom reported in the literature. Here, we describe the case of an 80-year-old male patient with primary appendiceal adenocarcinoma, who presented to China Medical University Hospital with mid-gastrointestinal tract bleeding. Capsule endoscopy revealed ...

Right lower quadrant pain is a symptom with an exceptionally broad differential diagnosis. Intussusception of the appendix is a very uncommon condition with many manifestations. Additionally, the pathologic finding of ectopic presence of a mixture of at least two mullerian-derived tissue components is rare. This report presents the case of a 49-year-old woman who presented twice with acute righ...

Endometriosis is a common disease generally, but appendiceal endometriosis causing acute appendicitis is a very uncommon clinical phenomenon and a few cases have been reported. The authors aim to highlight the rarity of such clinical entity in Nigeria. A 29 year old nulliparous woman presented with severe right iliac fossa pains, tenderness and rebound tenderness on her second day of menstruati...

Commercial trade of wild birds may devastate wild bird populations. Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) controls the trade of wild species listed in its appendices to avoid these species being threatened by international trade. China used to be one of the major trading countries with significant bird trade with foreign countries; on the other ...

To try to understand the source of the variability in suppressed M2AChR cEC50 data, we performed an experiment in which we repeated the same concentration of ACh (0.3 μM) at various intervals throughout a dose-response experiment (see Figure 3.22). Current responses to the same dose of agonist increased on average throughout the course of the experiments. More importantly, this change was not c...

Goblet cell carcinomas (GCC) are a rare, aggressive sub-type of appendiceal tumours with neuroendocrine features, and controversy exists with regards to therapeutic strategy. We undertook a retrospective review of GCC patients surgically treated at two tertiary referral centres. Clinical and histopathological data were extracted from a prospectively maintained database. Survival analyses utilis...

Primary tumors of the appendix are rare, comprising 1.1% of all appendectomy specimens. Nevertheless, it often presents in an emergent fashion, creating a need for a well-defined management algorithm that will ensure proper acute management. We performed a retrospective review of medical charts from 1982-2007 on all charts with a diagnosis of appendiceal neoplasm. A cohort of 41 patients was di...

PURPOSE Appendiceal tumors are a heterogeneous group of diseases that include typical neuroendocrine tumors (TNET), goblet cell carcinoids (GCC), and atypical GCC. Atypical GCC are classified into signet-ring cell cancers (SRCC) and poorly differentiated appendiceal adenocarcinoids. The prognosis and management of these diseases is unclear because there are no prospective studies. The aim of th...
