A tumoral lesion that includes four distinct components: a gastric composite tumor with liver metastasis.

چکیده
A composite carcinoma is a special tumor in which at least two different malignant cell types are blended. Such tumors have been documented in numerous gastrointestinal organs, but rarely occur in the stomach. Usually, they consist of an adenocarcinoma and neuroendocrine components (1-3). Here, we present a 64-year-old man with a gastric composite tumor including adenocarcinoma, neuroendocrine-, squamous cell-, and clear cell-carcinoma components. To our knowledge, no similar case has been reported in the English language literature to date. In addition to its exceptionality, this case demonstrates the metastases of three distinct components to the liver, which has not been reported previously.

متن کاملEvaluation of PDL-1 Protein Expression in Tumor Tissues of Patients with Gasteric Cancer
Background and Objective: Nowadays, it has been proven that the immune system plays a major role in the occurrence or treatment of some cancers. The PDL-1 proteins are among the components of the immune system, which are expressed in different body cells, including B cells and T cells. In this regard, the present study was conducted to determine the frequency of PDL-1 protein expression and its...
متن کاملRole of Helicobacter pylori on differential expression of angiogenic markers in gastric adenocarcinoma
Animal studies showed that male gastric tissues respond more rapidly to Helicobacter pylori (H.pylori) infection but the possible mechanisms remained unclear. There is no data about gender specific activity of Androgen receptor (AR) as an independent unfavorable prognostic factor in gastric cancer and its interactions with H.pylori and angiogenesis in both genders. To compare the pathogenesis o...

Dermatofibrosarcoma protuberans (DFSP) is a rare coetaneous sarcoma that originates from fibroblasts of dermis and presents as a non tender coetaneous nodule. Local slow invasion, recurrence after therapy and low risk of metastasis are its main specifications. Pathology and immunohistochemistry are used to diagnose and wide surgery is the best approach for treatment. We present a case of recu...

Background: Gastric cancer (GC) is one of the most prevalent cancers with a high rate of mortality in the world. In recent years, microRNAs (miRNAs) have been proposed to be involved in GC development. In this study, we aimed at investigating differential expression level of miR-155-5p, miR-15a, miR-15b, and miR-186 in GC. Methods: For this research, we used qPCR to investigate miR-15b, miR-155...
