Gastric metastasis and peritoneal carcinosis revealing primary breast cancer: an unusual presentation.

Breast cancer is the most frequent cancer among women. Gastrointestinal tract metastases are uncommon and might be misidentified as primary carcinoma.A noteworthy case-study involved 53-year-old-woman complaining from epigastric pain, ascites and overall health decline.

An Acute Jejunojejunal Intussusception Revealing a Metastatic Combined Lung Cancer.

Intussusception is a relatively common disease in pediatric age but it is uncommon in adults. We report a case of a 49-year-old male who presented with an acute jejunojejunal intussusception revealed by abdominal pain and vomiting. He underwent an en bloc resection, and pathological findings concluded to a metastasis of a pulmonary combined small cell carcinoma and adenocarcinoma.

Endobronchial schwannoma in adult: A case report.

Schwannomas are uncommon benign nerve sheath tumors and often arise in the posterior mediastinum and costovertebral angle. However, endobronchial schwannomas are rare. In fact, there are only a few reported cases in the literature.

Thyroid oncocytic neoplasms.

Background: Oncocytic tumors (OT) are rare, representing 3 to 10% of epithelial tumors of the thyroid. It is important to individualize these TO given the relatively high frequency of carcinomas in this group: 30% against 15% for micro-vesicular lesions of classical cytology and the aggressiveness of malignant OT due to their low iodine uptake.

Aim: The aim of our study was to describe the anatomo-clinical aspects of oncocytic tumors of the thyroid.

Evaluation of fine needle aspiration cytology in the diagnosis of cervical lymph node lymphomas.

Purpose: Surgical biopsy examination is the gold standard for the diagnosis of lymph node lymphomas. Fine-needle aspiration cytology (FNAC) is a quick and safe method in the management of cervical lymph nodes. Its value in confirming recurrent or residual lymphoma is well established.

ALK protein expression in pulmonary adenocarcinoma of Tunisian patients.

Background: It is now necessary to determine ALK status in order to use targeted therapy.

Aim: herein, we assess immunohistochemical profile of ALK protein in a series of Tunisian patients with pulmonary adenocarcinoma.

Materials And Methods: ALK protein expression was studied applying the D5F3 antibody with a fully automated Ventana CDx technique on a series of 19 patients.

Immunohistochemical expression pattern of MMR protein can specifically identify patients with colorectal cancer microsatellite instability.

The microsatellite instability (MSI) pathway is found in most cases of hereditary nonpolyposis colorectal cancer (HNPCC) and in 12 % of sporadic colorectal cancer (CRC). It involves inactivation of deoxyribonucleic acid mismatch repair (MMR) genes MLH1, MSH2, PMS2, and MSH6. MMR germline mutation detections are an important supplement to HNPCC clinical diagnosis.

Salivary duct carcinoma of the parotid gland.

Salivary duct carcinoma of the parotid gland is an uncommon tumor, highly aggressive. About 200 cases have been reported in the English literature. Pathomorphologically, these tumors showed great similarities to ductal carcinoma of the female breast, which is why they described this tumor as "salivary duct carcinoma.
