Over the past 25 years, 2921 appendicectomies were performed at this hospital. All were subjected to routine histopathological examination. In 95% of cases, histopathological examination did not add any further information but in 153 (5%) cases, clinically important pathological findings were detected for the first time. Seventy (2.3%) specimens showed typical evidence of tuberculosis. Parasitic infestation was detected in 75 (2.5%), including enterobiasis (1.4%), amoebiasis (0.5%), ascariasis (0.5%), ascariasis with trichuriasis (0.05%), and taeniasis (0.05%). Other lesions found were mucocele (0.1%) and carcinoid tumour (0.1%). It is concluded that routine histopathological examination of all appendicectomy specimens should be performed to avoid missing any clinically important and treatable condition.

Analysis was made of 436 specimens of appendectomy in the Caracas University Hospital during the year 1.990. Ages of the patients ranged between 9 months and 79 years (average age: 21 years). 236 were males and 200 females. The pathology found most frequently was the acute inflammatory processes, followed by secondary reactive changes to other entities, many of which were unspecified (e.g. pelvic inflammatory disease) and other specific (such as infestation by parasites) less frequently were found tumoral processes such as mucocele, carcinoid tumor and those which involved another portion of the digestive apparatus and which secondarily affect the appendix.

Subepithelial tumors are frequently found in asymptomatic patients in Japan and Korea where cancer screening tests routinely include endoscopy. Most lesions are asymptomatic and clinically insignificant. However, carcinoid tumors, lymphomas, glomus tumor and gastrointestinal stromal tumors (GISTs) are malignant or have the potential to become malignant. Inflammation due to parasitic infestation by Anisakis and poorly differentiated adenocarcinomas in the stomach rarely present as subepithelial lesions. In contrast to the frequency of gastric GIST in the gastrointestinal system, they are uncommon in the duodenum and very rare in the esophagus. The prognosis of patients with GISTs in the stomach is relatively good compared with GISTs in other organs. Along with the location of the tumor, its size and mitotic count are major factors that determine the malignant potential of GIST. Small (<2 cm) asymptomatic GISTs usually have benign clinical course. GIST is the most common subepithelial tumor to occur in the stomach. Although various methods are employed to diagnose GISTs, the risk of GIST metastasis cannot be accurately predicted before lesions are completely resected. Recently, new endoscopic diagnostic methods and treatment techniques have been developed that allow the diagnosis and resection of lesions located in the muscularis propria, without any complications. These endoscopic methods have different indications depending on regions where they are performed.
