1/236. Coexisting congenital sublingual dermoid and bronchogenic cyst. A congenital dermoid together with a bronchogenic cyst at the base of the tongue is extremely rare. We describe a 5-year-old boy who presented with an enlarged anterior segment of mandible, slight swelling of the left submandibular region, and a large swelling of the floor of the mouth that was displacing the tongue posteriorly. Both cysts were successfully excised and the boy made an uncomplicated recovery. Occlusion and mastication returned to normal and his speech improved remarkably. ( info) |
| A large cystic mass was found in the subdiaphragmatic region of a 46-year-old woman who had complained of continuous pain in the left flank . The cyst was located in the retroperitoneum just below the diaphragm and was adhered to the diaphragmatic skeletal muscle and abdominal aorta, but was separate from the spleen, pancreas, left adrenal gland and left kidney. The surgically resected cyst measured 8 x 8 x 7 cm and was filled with protein-rich fluid, which contained amylase and embryonal proteins such as carcinoembryonic antigen, CA125 and CA19-9. Histologically, the cyst wall was composed of a fibrovascular connective tissue containing thin smooth muscle layers and mucus-secreting glands and was lined by a ciliated pseudostratified or tall columnar epithelium without dysplastic changes. Thus, a diagnosis of bronchogenic cyst, which is usually discovered in the posterior part of the mediastinum, was made. A rare case of bronchogenic cyst and a literature review is presented.

| The unusual case of acute respiratory insufficiency in an infant of 5 months caused by a large cyst of true tracheal origin is presented. ( info) |
4/236. A bronchogenic cyst in an infant causing tracheal occlusion and cardiac arrest. A 3-month-old infant treated for 3 weeks for suspected bronchiolitis, developed episodes of profound desaturation. A lateral X-ray showed displacement and compression of the trachea. Respiratory arrest, from which she was successfully resuscitated, occurred just before MRI scan. The mass was removed at thoracotomy and a histological diagnosis of a bronchogenic cyst was made. Mediastinal masses in babies are relatively rare, and the situation in which they present with acute respiratory distress may prove extremely challenging to the anaesthetist. Bronchogenic cysts are difficult to diagnose pre-operatively and awareness may assist in the peri-operative management of these infants. ( info) |
5/236. A retroperitoneal bronchogenic cyst with malignant change. A unique case of adenocarcinoma arising in a retroperitoneal bronchogenic cyst is presented. A 55-year-old woman presented with lower abdominal discomfort. Computed tomography revealed a retroperitoneal cystic mass attached to the ascending colon. The resected cyst was unilocular and filled with milky white mucus and hemorrhagic debris. Histologically, most of the cyst wall was of well-differentiated papillary adenocarcinoma with no cyst wall invasion. Other small areas of the cyst were lined with variably atypical dysplastic/metaplastic cuboidal to pseudostratified columnar epithelium. The cyst wall was mostly hyalinized, but there was apparent thickened subepithelial basement membrane, elastosis, and a single layer of smooth muscle that suggested bronchial wall structures. A mucin staining study with O-acylated sialic acid, which is used for the demonstration of gastrointestinal, cholecystic and uterine cervical mucins, was negative for the mucin-producing epithelial cells of the cyst. Thus, to our knowledge, this is the first reported case of adenocarcinoma arising in a retroperitoneal bronchogenic cyst. ( info) |
| Congenital bronchogenic cysts of the lung and mediastinum develop from the ventral foregut during embryogenesis. These cysts are often incidental radiologic findings in adults, but patients can be seen with symptoms of chest pain, cough, dyspnea, or any combination of these. Acute presentations are unusual and have rarely been reported. We present the unique case of a 36-year-old man seen with an acute coronary syndrome and sudden hemodynamic collapse. The patient sustained a massive and ultimately fatal myocardial infarction, compression of the left main coronary artery by a bronchogenic cyst was demonstrated at postmortem examination. If detected, bronchogenic cysts should be surgically excised to limit associated morbidity and mortality. ( info) |
7/236. Isolated retroperitoneal intradiaphragmatic bronchogenic cyst. A case report. Isolated retroperitoneal bronchogenic cysts are extremely rare. We report a case which was intradiaphragmatic intimately associated with the musculature of the left crus diaphragmatic and unconnected with any other structures. Ultrasound and computed tomography findings were consistent with a pancreatic or an adrenal mass. pathology confirmed a bronchogenic cyst. The outcome is favourable and the overall prognosis is good.

| A 19 year-old man with a history of dysphagia and chest pain was diagnosed as having a cyst of the esophagus by endoscopic ultrasonography and magnetic resonance imaging. The patient's bronchogenic cyst was treated by video-assisted thoracoscopic excision with mini-thoracotomy. This procedure is applicable for patients who require repair of the esophageal wall after excision of a lesion and reduces post-operative complications. ( info) |
9/236. bronchogenic cyst presenting as a nodular lesion. We report a subcutaneous bronchogenic cyst in a 7-year-old girl with unusual presentation as a nodular lesion. The cyst was excised and no connection with deeper structures was found. Histologic examination showed the typical features of a bronchogenic cyst. The characteristic clinical and histologic features of bronchogenic cysts are reviewed. The problems of differential diagnosis are also discussed. ( info) |
10/236. bronchogenic cyst of the left lower lobe associated with severe hemoptysis. Bronchogenic cysts result from congenital disorders, are often asymptomatic at diagnosis, but complications are not uncommon. We report the case of a 19-year-old woman with severe hemoptysis. This rare presentation of an intrapulmonary bronchogenic cyst should be considered as differential diagnosis in patients with cavernous lesion of a lobe. Surgery was performed as a diagnostic and therapeutic measure. ( info) |
