Gastric carcinoids are classified into three different subgroups: Type I, Type II, and Type III (L. Vannella et al., 2011). Type I gastric carcinoids cause atrophic body …show more content…
Vannella et al., 2011). Type I gastric carcinoids are 75% of all gastric carcinoids and occur in 1-2% of ABG patients (Delle Fave G. et al., 2012). Type I Gastric Carcinoids, are generally present in 77% of cases as multifocal polypoid mucosal protrusions (<10 mm) in the corpus and/or fundus of the stomach (G. Cadiot et al., 2010). 27% are limited to the mucosa, 64% only invading to the mucosa and/or submucosa and only 9% invading the muscularis propria (G. Cadiot et al., 2010). Type I gastric carcinoids are usually not invasive. The person usually has multiple carcinoids if type I is present, and they usually are well differentiated. Type I gastric carcinoids are asymptomatic. They are usually discovered during a routine upper gastrointestinal endoscopy for other …show more content…
Type I Gastric Carcinoids, 9 out of 367 (2.4%) patients [six women, median age 59 (range 40-72) years] were diagnosed with type I gastric carcinoids at the initial diagnosis of CAG (L. Vannella et al., 2011). The chart shows that all patients besides one had polys of the body with a diameter between 0.3 and 3 cm at gastroscopy (L. Vannella et al., 2011). In six out of nine (66.7%) patients with type I gastric carcinoids, the body gastric mucosa presented a severe atrophy, in the remaining cases the atrophy was moderate (L. Vannella et al., 2011). 40% of the patients had a recurrence rate.
