Surgical resection of a giant primary liposarcoma of the anterior mediastinum.

This case describes the incidental finding and surgical removal of an 1.8-kg liposarcoma in the anterior mediastinum. These tumors are very rare and would normally present with symptoms of intrathoracic compression; however, this patient was completely asymptomatic. The case presentation and treatment rationale are described along with a brief review of existing literature.

A Rare Case of Diffuse Idiopathic Pulmonary Neuroendocrine Cell Hyperplasia.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare clinical condition with only about 100 cases reported in the literature. It is characterized by primary hyperplasia of pulmonary neuroendocrine cells (PNECs) which are specialized epithelial cells located throughout the entire respiratory tract, from the trachea to the terminal airways. DIPNECH appears in various forms that include diffuse proliferation of scattered neuroendocrine cells, small nodules, or a linear proliferation. It is usually seen in middle-aged, nonsmoking women with symptoms of cough, dyspnea, and wheezing. We present a 45-year-old, nonsmoking woman who presented with symptoms of DIPNECH associated with bilateral pulmonary nodules and left hilar adenopathy. Of interest, DIPNECH in our patient was associated with metastatic pulmonary carcinoids, papillary carcinoma of the left breast, oncocytoma and angiomyolipoma of her left kidney, and cortical nodules suggestive of tuberous sclerosis. She had video assisted thoracoscopic surgery (VATS), modified radical mastectomy with reconstruction, and radical nephrectomy. She is currently symptom-free most of the time with over two years of follow-up.

EVICEL glue-induced small bowel obstruction after laparoscopic gastric bypass.

Small bowel obstruction is a complication of laparoscopic Roux-en-Y gastric bypass (LRYGB) frequently caused by adhesions and internal hernia. In addition, anastomotic leak that complicates LRYGB surgery contributes to the mortality of this procedure. Fibrin glue is commonly used intraoperatively for prevention of anastomotic leak and to secure hemostasis. We describe 2 cases of morbidly obese women who underwent LRYGB surgery for weight loss and developed early postoperative small bowel obstruction related to the use of the "EVICEL" fibrin sealant. Of note is that both patients required surgical intervention for this complication.
