1/72. 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.

2/72. Mediastinal bronchogenic cyst manifesting as a catastrophic myocardial infarction.

    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.

3/72. Thoracoscopic excision with mini-thoracotomy for a bronchogenic cyst of the esophagus.

    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.

4/72. bronchogenic cyst appearing as a hepatic mass.

    Because bronchogenic cysts may be found in or near any organ derived from the embryonic foregut, they sometimes pose considerable diagnostic difficulties. We describe the plain chest X-ray, computed tomographic, and angiographic findings in a patient with elevated CA 19-9 and upper quadrant abdominal pain due to a cystic tumor appearing as a hepatic mass. Surgery and histology showed a bronchogenic cyst located in the lower lobe of the right lung.

5/72. Presternal bronchogenic sinus with predunculated lymphoid aggregate.

    Congenital cranial, cervical, and upper thoracic sinuses are rare conditions that historically have been classified according to their location and/or pathology. However, published reports of bronchogenic or branchial anomalies are on the increase, and the traditional defining characteristics--location and histopathology--are proving to be less reliable. We describe the pathologic and clinical findings of a congenital presternal pedunculated lesion with a sinus, and review the literature to describe its proper classification.

6/72. A paraesophageal bronchogenic cyst with esophageal communication.

    Paraesophageal bronchogenic cysts are a rare developmental anomaly of the upper digestive tract. Although often asymptomatic, their growth can cause severe symptoms and complications because of the location. The diagnosis is difficult and is mostly by histopathologic findings after extirpation of the cyst. The authors present a case of a paraesophageal bronchogenic cyst, of typical histologic structure (ciliated epithelium and hyaline cartilage) connected with the esophageal lumen by a narrow canal composed of stratified squamous epithelium. According to the available literature, only three cases of bronchogenic paraesophageal cysts with esophageal communication have been reported.

7/72. bronchogenic cyst. A rare differential diagnosis of retroperitoneal tumors.

    Subdiaphragmatic bronchogenic cysts are rare, and those located retroperitoneally are exceptional. A review of the English-language literature revealed only 16 reported cases. We describe an additional case of a retroperitoneal cyst presenting as an asymptomatic adrenal mass and discuss clinical, radiographic, surgical and pathological findings as well as its embryological background.

8/72. Thoracoscopic resection of the pulmonary aspergilloma: report of two cases.

    Pulmonary aspergillomas causing hemoptysis were successfully resected through videothoracoscopy in two cases. We removed an aspergilloma located in the right lower lobe of the lung in a 48-year-old woman with a bronchial cyst and rheumatoid arthritis. We also removed an aspergilloma located in the left upper lobe of the lung in a 59-year-old man with emphysematous bullae and diabetes mellitus. In both cases, the aspergillomas were removed by pulmonary wedge resection through scheduled thoracoscopy.

9/72. Paravertebral and diaphragmatic mass: an ectopic location of bronchogenic cyst.

    Bronchogenic cysts constitute one area of the broad spectrum of developmental anomalies of the primitive foregut. They arise from anomalous budding of the primitive tracheobronchial tube and are commonly located in the mediastinum or the lung parenchyma, closely related to the tracheobronchial tree. In rare cases, they can migrate to subpleural, pericardial, paravertebral and cervical locations, if embryological connections with their parent bronchus are lost. Plain chest radiography and computed tomography have been the primary imaging modalities used for diagnosis. Computed tomography is frequently associated with misleading information with respect to the cyst density. magnetic resonance imaging has been shown to be useful in the differential diagnosis of cystic mediastinal masses. We present a patient with two asymptomatic bronchogenic cysts found at a distance from the tracheobronchial tree.

10/72. A fetal lung lesion consisting of bronchogenic cyst, bronchopulmonary sequestration, and congenital cystic adenomatoid malformation: the missing link?

    A fetus was found to have a large left thoracic cyst on routine prenatal ultrasound at 23 weeks of gestation. This lesion caused compression of the normal left lung tissue and contralateral mediastinal shift. At 23 weeks of gestation the cyst was percutaneously aspirated without subsequent reaccumulation of fluid. Serial ultrasounds showed decrease in the size of the cyst. The clinical diagnosis of congenital cystic adenomatoid malformation was made. At birth, the child had no respiratory distress, and a CT scan confirmed the finding of a fluid-filled cyst in the left chest. At the time of resection, a nonaerated extralobar bronchopulmonary sequestration (with a systemic arterial blood supply and separate pleural investment) was found. The dominant cyst had ciliated respiratory epithelium with cartilage, indicative of a bronchogenic cyst, and the remainder of the specimen had the histologic hallmarks of a congenital cystic adenomatoid malformation. The coexistence of three separate anomalies in one lesion suggests a common embryological link for these malformations.
