Laparoscopic excision of subdiaphragmatic epidermoid cyst: a case report

Retroperitoneal epidermoid cysts are rare. The authors report a case of an 11-year-old boy with an asymptomatic subdiaphragmatic cyst, which was found incidentally during an investigation for hypertension. At laparoscopy, the cyst was densely adherent to the diaphragm, resulting in a pneumothorax during dissection. Nevertheless, the excision and the diaphragmatic repair could be completed laparoscopically without complication. Microscopic examination showed an epidermoid cyst. No similar case has been reported in the literature.     

Retroperitoneal bronchogenic cyst: a case report

A rare case of retroperitoneal bronchogenic cyst is presented. A 50-year-old man was referred to our hospital for an investigation of a retroperitoneal mass. Computed tomography and magnetic resonance imaging confirmed a retroperitoneal mass, about 4 cm in diameter, adjacent to the left kidney and spleen. On the basis of these imaging modalities, a definitive diagnosis of this mass could not be made. So, resection of the mass was performed. The removed mass was an unilocular cyst and filled with mucinous fluid. Histopathologically, the cyst wall was composed of a fibrovascular connective tissue containing mucus-secreting glands and cartilages and was lined by ciliated pseudostratified columnar epitherium. Thus, a diagnosis of bronchogenic cyst was made. Bronchogenic cysts are rare congenital anomalies of the primitive foregut and usually develop in the mediastinum and lung.     

Diaphragmatic bronchogenic cyst: a rare case report

Retroperitoneal bronchogenic cysts are rare and those located in the diaphragm are exceptional. We describe an additional case of bronchogenic cyst of the left crus of diaphragm. Diagnosis of a diaphragmatic lesion was confirmed during laparotomy and complete resection was successful. Final diagnosis was done on pathology.     

Supradiaphragmatic bronchogenic cyst extending into the retroperitoneum

We experienced a case of bronchogenic cyst located on the left lower pleural space extending into the retroperitoneum in a 33-year-old man with left chest pain. Preoperative imaging studies and operative findings showed a broad-based cystic mass on the left lower posterior pleura and diaphragmatic pleura extending into the retroperitoneal region across the diaphragm. Histologic studies proved this mass to be a bronchogenic cyst.     

Laparoscopic exploration of the retroperitoneum in a gunshot victim: A case report

IntroductionNon-operative management and minimally invasive surgery reduce the burden of negative laparotomies in patients with penetrating gunshot wounds (GSW). Careful patient selection is key. Although challenging, in experienced hands laparoscopic exploration of the retroperitoneal space can be carried out.Case presentationA 38year old man was brought to the emergency room after sustaining a GSW to his right groin. Due to evidence of intoxication, clinical picture was unreliable, although the patient was hemodynamically stable and there were no signs of peritonitis. Furthermore, the presence of retained bullet fragments created significant artifact on imaging. Clinical and radiological uncertainty urged us to proceed with laparoscopic exploration. Following mobilization, the ascending colon wall was fully inspected and no injury was identified. The pelvic fracture was managed non-operatively. After an uneventful hospital course, the patient was discharged home in stable condition and outpatient follow up was re-assuring.DiscussionAvoiding morbidity from missed colonic injury is important, particularly in patients with unclear clinical and radiological findings, that were present in our case. Non-operative management by serial examination and minimally invasive surgical techniques are considered an alternative to the classical exploratory laparotomy approach. Furthermore, utilization of laparoscopy in retroperitoneal injury has gained much attention in the recent years particularly in well-established centers.ConclusionLaparoscopic exploration is a safe and effective surgical approach in patients who have sustained GSW to the abdomen and to the retroperitoneal space. However, it requires careful patient selection and surgical expertise.     

Laparoscopic excision of prostatic hydatid cyst: case report and review of literature

It is rare for hydatid disease to be encountered primarily in the urogenital system or retroperitoneum. Moreover, prostatic involvement is extremely rare. We present a case report of prostatic hydatid cyst that was treated with laparoscopic excision. We reviewed diagnosis and management of hydatid disease of the urogenital tract.     

Retroperitoneal bronchogenic cyst: a case report and review of the literature

This unusual clinical case adds itself to the limited list of existing reports of retroperitoneal bronchogenic cysts in the international literature. It emphasizes the difficulties encountered in making a preoperative diagnosis, since these lesions can be described as both solid and cystic masses. A 69-year-old man underwent surgery to remove an expanding mass diagnosed as originating in the adrenal gland and discovered during clinical investigation for other indications. The lesion was excised only after adrenalectomy whereupon its cystic nature was revealed. Retroperitoneal bronchogenic cysts, though rare, should be considered in the differential diagnosis of retroperitoneal expanding lesions, especially in the presence of cystic tumours of the left adrenal region. This is the first case of a retroperitoneal bronchogenic cyst reported in an adult in Italy.     

Laparoscopic excision of a rare type II choledochal cyst: case report and review of the literature

Although once considered rare, choledochal cysts now are extensively reported on and have an official anatomic classification. The authors report a case of a 4-year-old girl whom on routine abdominal ultrasound as follow-up for vesicoureteral reflux was found to have a choledochal cyst. Follow-up hepatobiliary scan together with the ultrasound findings was consistent with a rare type II choledochal cyst. On laparoscopy, a type II choledochal cyst was confirmed on dissection and amenable to laparoscopic excision. Intraoperative cholangiogram after excision showed normal remaining biliary anatomy. The patient was discharged the following day without delayed complications on follow-up visits. This report suggests a role for laparoscopic surgery in the definitive management of selected cases of choledochal cystic disease. (Included is relevant radiological documentation, illustration of technique, and review of the literature.)     

Incomplete duplication of trachea with bronchogenic cyst: a case report

Tracheal duplication is a very rare infant congenital airway anomaly. We report a bronchogenic cyst communicating with a tracheal duplication. This is the first reported case of pathologically confirmed duplication of trachea communicating with a bronchogenic cyst.     

Large bronchogenic cyst of stomach: A case report

IntroductionBronchogenic cysts are congenital cysts arising as an abnormal budding from primitive tracheobronchial tree. They are lined by pseudostratified columnar or cuboidal ciliated epithelium and contain smooth muscle fibers, submucosal bronchial glands and/or cartilage. They are most frequently located in the mediastinum or the lung parenchyma. Intramural occurrence of bronchogenic cyst in the gastric wall is very rare.Presentation of caseWe present a case of 65-year-old lady with a 7 × 8 cm lesion in the gastric cardia suspicious of gastrointestinal stromal tumor. Because of the large size, total gastrectomy with Roux-en-Y esophagojejunal anastomosis was performed. The postoperative course was uneventful. Histopathological examination revealed a sub-mucosal cyst lined by PCCE with presence of smooth muscle fibers and focal mucous glands. Final diagnosis of bronchogenic cyst was made. On the last follow up at one year, she was symptom free.DiscussionOn extensive Medline/Pubmed search, only 38 cases of gastric bronchogenic cysts were found to be reported till date. They are typically located in the posterior gastric wall close to the gastric cardia. On radiological imaging, they appear as well defined intramural cystic lesion without any characteristic features. Surgical resection is considered in symptomatic cases or in case of diagnostic dilemma.ConclusionGastric bronchogenic cysts often mimic gastrointestinal stromal tumor on preoperative imaging. They should be included in the differential diagnosis while dealing with an intramural gastric lesion close to the cardia or gastroesophageal junction.

Laparoscopic excision of ciliated hepatic foregut cyst: a first report in Korea

Ciliated hepatic foregut cyst (CHFC) is very rare and apparently originated from embryologic foregut. It is generally benign, solitary cyst and microscopically consists of inner ciliated pseudostratified columnar epithelium, subepithelial connective tissue, a smooth muscle layer, and outer fibrous capsule. Although ciliated cysts commonly arise from the tracheal bronchial tree and the esophagus, they could also be found in the liver with rare incidence. There are several reports indicating this lesion can cause clinical problems, such as biliary obstruction and malignant transformation. Herein, we present a case of 56-year-old male patient who recently underwent laparoscopic excision of CHFC, focusing our discussion on review of literatures and rationale of laparoscopic surgery on CHFC.     

Subdiaphragmatic bronchogenic cyst in the left crus of diaphragm: report of a case

A 39-year-old man who had a subdiaphragmatic bronchogenic cyst in the left crus of diaphragm received surgical treatment. The cyst was located in the retroperitoneum just below the diaphragm and was adhered to the left crus of diaphragm and unconnected with any other structures. The surgically resected cyst was 50 x 25 x 22 mm diameter and the wall was thin and contained white turbid mucus. Histologically, the cyst consisted of ciliated epithelium, mucus glands, smooth muscle, cartilage and this evidence established the final diagnosis of bronchogenic cyst. The post operative course was uneventful and the patient was discharged 10 days after operation. This is the 4th reported case of a subdiaphragmatic bronchogenic cyst in the Japanese literature.

A case report of a paraesophageal bronchogenic cyst and an esophageal cyst]

There are relatively few paraesophageal bronchogenic and esophageal cysts in mediastinal tumors. It is often difficult to distinguish between these cysts. Case 1: 11 year old, male with no symptoms. An abnormal tumor shadow was revealed by chest roentgenogram. Before operating, CT, MRI and other laboratory tests were suggested that the tumor was neurogenic. A cyst with a pedicle connected to the esophageal muscle layer was found during the operation. Pathological examination confirmed a bronchogenic cyst lined with cartilage. Case 2: 38 year old female with epigastralgia. Upper gastrointestinal series revealed that the thoracic esophagus was smoothly compressed from the outside. CT and MRI showed a well-defined cystic mass in the posterior mediastinum. The cyst bordered the esophagus, but there was no direct communication between them. The pathological findings showed the presence of a double layer of smooth muscle without cartilage which was diagnosed as an esophageal cyst.     

Laparoscopic management of a giant adrenal cyst: case report

A 22-cm left adrenal cyst in a 30-year-old woman was laparoscopically drained and then excised. The main symptom was dull left-upper-quadrant pain. Operative time was 95 minutes, and the hospital stay was 1 day. The patient returned to normal activity 7 days after surgery. Histology revealed a benign adrenal cyst. At the 3-month follow-up, ultrasonography showed the absence of any cystic recurrence, and adrenal endocrine function was normal. The advantages and disadvantages of this modality for the management of adrenal gland cysts are discussed.
