Isolated omental panniculitis (IOP), a rare form of acute abdominal syndrome, is defined as intraabdominal panniculitis that involves only omentum without extraabdominal fat necrosis, inflammatory bowel disease and pancreatitis. In the search made using PubMed English database, only 4 cases are determined with IOP. IOP is conceptually confused with idiopathic omental infarction (IOI). However, omental infarctions that are rare causes of acute abdominal syndromes were published by Bush for the first time in 1986 and less than 400 cases were reported. In this article we aimed to publish 2 IOP patients who applied with acute abdominal manifestation and were treated with laparoscopic omental resection to discuss the other 4 IOP cases comparing with IOP together with literature.

Primary lung tumors mimicking the salivary gland–type neoplasms are extremely rare. These types of tumors originate from submucosal bronchial glands. Epithelial-myoepithelial carcinoma is an uncommon tumor in this group, and only 7 cases have been reported. It is considered to be a low-grade malignant neoplasm. We report a case of epithelial-myoepithelial carcinoma of bronchial gland origin in a 73-year-old man who presented with coughing and dyspnea. The bronchus of the left lower lobe contained a tumor mass that had a polypoid growth pattern. The tumor also extended into the pulmonary parenchyma, forming a well-circumscribed mass with a pushing margin. The tumor consisted of epithelial and myoepithelial cells. The epithelial cells were positive for cytokeratins and epithelial membrane antigen, while the myoepithelial cells were positive for S100 protein and muscle-specific actin. According to these findings, we diagnosed epithelial-myoepithelial carcinoma. After undergoing pneumonectomy, the patient has been disease free for 34 months.
