This report describes a rare case of adenocarcinoma arising from a gastric duplication cyst, with invasion to the stomach wall, in a 40 year old Japanese man. A cystic lesion was found between the stomach and the spleen. The cyst had a well circumscribed smooth muscle layer, corresponding to the muscularis propria of the stomach and the mucosa of the alimentary tract. A well differentiated adenocarcinoma was found within the duplication cyst, invading its serosa. Well differentiated adenocarcinoma was independently found in the fundus of the stomach; the tumour of the cyst was connected by fibrous tissue. Microscopically, there was neither adenocarcinoma in situ nor precancerous lesions, such as epithelial dysplasia, suggesting that the carcinoma derived from a gastric duplication cyst that invaded the stomach. Duplication cysts should be included in the differential diagnosis of cystic masses of the gastrointestinal tract, and the possibility of malignancy within these cysts should be considered.

“…3 Carcinoma arising from a duplication cyst is extremely rare, with only five cases having been reported in gastric duplication cysts to date. [4][5][6][7][8] We present a case of adenocarcinoma arising from a gastric duplication cyst with invasion to the stomach wall in a 40 year old Japanese man, together with a discussion of the literature.…”

“…The former is usually seen in the small and large bowel [8]. Nine cases of adenocarcinoma arising from gastric duplication cysts [3][4][5][6][7][8][9][10] have been reported, including the present case (Table 3). Little information is available on the differences in cancer development between the tubular and spherical types in alimentary tract duplication (Table 2), but all nine cases of cancer development derived from gastric duplication cysts were spherical types.…”

“…These lesions are located on the mesenteric aspect of the alimentary canal, sharing a common muscular wall and blood supply, but having a separated mucosal lining [1]. As the majority of patients with alimentary tract duplications are diagnosed and treated in childhood, adults with those lesions are relatively rare but reports on cancer development arising from duplication cysts have occasionally been published as adult cases [2][3][4][5][6][7][8][9][10][11].…”

Gastric duplication is a rare congenital malformation. We report the case of a 50-year-old man with adenocarcinoma derived from gastric duplication. He was referred to our institute because of persistent vomiting due to pyloric stenosis. Abdominal computed tomography revealed two cystic lesions: a 2-cm mass located along the greater curvature of the upper gastric corpus and a 3-cm mass adjacent to the bulbus. Under the diagnosis of gastric duplication cysts, the oral cyst was removed with the gastric wall and the other cyst lesion firmly adhered to the bulbus was treated with distal gastrectomy. Based on histological findings showing adenocarcinoma in the anal duplication cyst wall and regional lymph node metastases and cancer invasion into the duodenal stump, pancreatoduodenectomy was performed 9 days after the initial surgery. Invasion into the pancreas head and duodenal walls was seen in the resected specimen. Although the postoperative course was uneventful, he died of local recurrence and multiple liver metastases 14 months after surgical treatment. This case report with literature review indicates that alimentary tract duplication cysts should be recognized as risky lesions of cancer development in patients aged 50 years or over.

“…Most duplication cysts do not communicate with the ordinary mucosa, and are characteristically located on the distal greater curvature [8]. A few duplication cysts have been reported to be affected by intramucosal carcinoma, probably due to persistent chronic inflammation [9], and such cysts have been detected in a few cases by advanced adenocarcinomas arising in them [8,10], and they may also even be replaced by a carcinoid tumor in the small bowel [11].…”

Adenocarcinoma arising in an intramural diverticulum presenting as a long-standing submucosal tumor

We report a rare case of adenocarcinoma arising in a gastric partial diverticulum in the upper portion of the stomach. The lesion had been followed up for approximately 14 years as a gastric submucosal tumor. However, a recent regular check-up revealed mucous material with some neoplastic tissue discharged from the top of the lesion. A surgically resected specimen showed a well-demarcated submucosal lesion identical to a pseudodiverticulum carrying a distinctive intramucosal minimally invasive adenocarcinoma in part, with surrounding nonneoplastic but hyperplastic mucosal components. Intestinal phenotype, along with gastric foveolar, pyloric gland-type phenotypes, and neoplastic cells with neuroendocrine differentiation, were also identified in the adenocarcinoma. Chronic and persistent irritation within the diverticulum was postulated to be implicated in the carcinogenesis of the lesion, which carried no definite Helicobacter pylori microorganisms. We believe it is crucial not to overlook carcinoma in a diverticulum presenting as a long-standing submucosal tumor.
