Intrasternal respiratory epithelium–lined foregut cyst

Abstract

oregut or enterogenous cysts are the result of an abnormal budding or division of the primitive foregut and are usually found in adults. On the basis of histologic features and embryogenesis, they are classified into bronchogenic, esophageal, gastroenteric, and neuroenteric cysts and usually occur in the mediastinum or, less frequently, in the soft tissues of the chest wall. 1 Intrasternal foregut cysts lined by respiratory epithelium have never previously been described in the literature, and we present here the first case.

Pancreatitis because of foregut duplication cyst of the pancreas treated by laparoscopic resection

“…In cases associated with enteric duplication cysts of the pancreas, recurrent abdominal pain, sometimes associated with recurrent pancreatitis, is the most common presenting complaint [3]. These cysts often contain acidsecreting gastric mucosa that causes symptoms secondary to peptic ulceration and subsequent chemical pancreatitis [6]. In our patient, the symptoms were because of pancreatitis from mechanical enlargement of the cyst into the pancreatic parenchyma.…”

Heterotopic Respiratory Mucosa in the Rectum: An Unusual Type and Site of Heterotopia in the Gastrointestinal Tract

“…HRM has been reported in other organs including the eye, thyroid, mandible, tongue, manubrium sterni, skin, and uterus with or without a salivary gland component. [4][5][6][7][8][9] Most of the reported HRM lesions were described as cystic lesions in the literature.…”
