A Patient with Duodenal Mucinous Adenocarcinoma Presenting as a Laterally Spreading Tumor
نویسندگان
چکیده
Primary duodenal carcinoma is rare. Duodenal mucinous adenocarcinoma (DMA) is even rarer, and its associated manifestations and typical endoscopic or imaging findings are not well characterized. Herein, we report a case of primary DMA in an asymptomatic 58-year-old man who visited our hospital for a regular health screening. Upper endoscopy revealed an approximately 4-cm lesion in the second portion of the duodenum, but the mass was not visualized on computed tomography. Biopsies revealed a tubular adenoma that was subsequently resected. Frozen biopsies demonstrated DMA with a background of low-grade tubular adenoma for which we performed Roux-en-Y duodenojejunostomy and jejunojejunostomy. To our knowledge, this is the first report of a patient with DMA in Korea.

Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma). In patients with mucinous adenocarcino...
متن کاملMucinous and Non-Mucinous Adenocarcinoma in Colorectal Cancer Patients
Background: The oncologic behavior of mucinous adenocarcinoma (MA) of colorectal differs from non-mucinous adenocarcinoma (NMA). MA is more advanced at diagnosis and has a poorer prognosis than NMA. We aimed to evaluate prognostic factors and survival rate in patients with MA compared with NMA in Western Iran. Methods: During 2008-2015 in a retrospective study, 83 patients with CRC referred to...
متن کاملAnalysis of TP53 Codon 72 Polymorphism in Mucinous and Non-Mucinous Colorectal Adenocarcinoma in Isfahan, Iran
Background: The tumor suppressor gene TP53 (alias p53) located on chromosome 17 is involved in various cancers. Case-control studies have shown that p53 codon 72 polymorphism modulates the prognosis and susceptibility to various malignancies. We undertook the present study to explore a possible association between mucinous and non-mucinous adenocarcinomas with different genotypes or alleles at ...

Duodenal adenocarcinoma is a rare malignancy and carries a poor prognosis. The role of adjuvant therapy and the optimal chemotherapy regimen remain largely unclear. Treatment with trastuzumab results in prolonged survival in gastroesophageal cancer if human epidermal growth factor receptor 2 (HER2) is overexpressed or amplified in tumor cells. However, unlike gastric adenocarcinomas, duodenal c...

A 59-year old patient was admited to the Gastroenterology Clinic with the signs of gastrointestinal bleeding. Computerized tomography (CT) and a barium-meal radiography revealed a circumferential nodular wall narrowing and incomplete stricture at the D2 part of the duodenum. CT also showed a poorly demarcated mass in the upper and lower poles of the left kidney. During the operation, the whole ...
