Metastatic Small Intestinal Cancer of the Urinary Bladder
نویسندگان
چکیده
We report an extremely rare case of small intestinal cancer metastasized to the urinary bladder, presenting a urologic symptom. A 41-year-old man first presented with nausea, vomiting and abdominal pain. Based on the clinical diagnosis of jejunal cancer, he underwent a partial resection of the jejunum with lymph node dissection. The pathological diagnosis was moderately differentiated adenocarcinoma of the jejunum, pT4N0. Seventeen months after surgery, he presented with a gross hematuria. Computed tomographic scan showed wall thickening of the posterior wall of the urinary bladder. No tumor was found in other organs or lymph nodes. Based on histological and immunohistochemical analysis, the diagnosis of urinary bladder metastasis from jejunal adenocarcinoma was made. This is the first report of urinary bladder metastasis from small intestinal cancer. Although very rare, the possibility of metastatic small intestinal cancer should be considered in differential diagnosis in patients with adenocarcinoma involving the urinary bladder.

We present a 55-year old male patient who was subjected to whole body skeletal scintigraphy for metastatic work up of urinary bladder cancer. Whole body 99mTc-methylene diphosphonate (MDP) skeletal scintigraphy was performed.

Small bowel tumors are very rare and generally malignant. As a result of the anatomical location and nonspecific manifestations of small bowel tumors, they are very difficult to diagnose. Balloon-assisted enteroscopy is a relatively noninvasive method compared to surgical resection, and allows for real-time observation, tissue confirmation with biopsy, and interventional procedures. Here, we re...

Background: E-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. Loss of the adhesive function of E-cadherin seems to promote invasive and metastatic properties of neoplastic cells. Objectives: The present study is a retrospective study aiming to evaluate the loss of E-cadher...
