Laparoscopic partial splenectomy for congenital splenic cyst in a pediatric patient: Case report and review of literature

Non-parasitic splenic cysts (NPSC) are a rare condition that makes difficult to know their true incidence and represent 10% of all benign splenic cysts, they can be either congenital with the presence of epithelial lining that originate from invagination of the capsular mesothelial lining or post-traumatic with absence of epithelial lining. We present our management of a splenic congenital cyst in a pediatric patient. A 10-year-old female patient presented to the clinic complaining with a 3-week abdominal pain at the left upper quadrant. An ultrasound showed an enlarged spleen with a thinned walled cystic image on the lower pole of 5 cm. An abdominal CT confirmed the presence of a splenic cyst at the lower pole of the spleen of 5 cm in diameter. Three-port laparoscopic partial splenectomy was done isolating and dividing the lower splenic artery and vein and the lower pole of the spleen with a vessel sealing device. Management of a non-parasitic splenic cyst is controversial: cystectomy, fenestration, percutaneous drainage and sclerotherapy have been previously described, most of them aiming to preserve spleen function and avoiding overwhelming post-splenectomy infection. Partial splenectomy seems the most effective one in terms of preserving spleen function and avoiding recurrence.     

Posttraumatic cyst of the spleen: a case report and review of the literature

Splenic cysts are rare lesions. They are mainly divided into primary or genuine cysts and secondary or false cysts according to their etiology and pathophysiology. Primary cysts have a cellular lining that can be caused by either congenital events or parasitic infestations (Echinococcus). Secondary cysts have no cellular lining and may be of hemorrhagic, serous, inflammatory, or degenerative origin. It is important for surgeons to assess each individual case and decide on the most suitable treatment, taking into account the features of the cyst, the time of onset, and the age of the patient, to avoid possible complications. We report a case of posttraumatic pseudocyst treated successfully by splenectomy and we review the literature.     

Neonatal congenital pancreatic cyst: diagnosis and management

Congenital pancreatic cysts are extremely rare in newborns. The case of a neonatal congenital pancreatic cyst with pancreatitis is reported. The rapid increase in cyst size concomitantly with clinical symptoms prompted surgical management. Intraoperatively, the pancreatic head showed signs of chronic pancreatitis, and in attempts to preserve most of the functional pancreatic tissue, a Roux-en-Y cystojejunostomy was performed. Histology demonstrated a true pancreatic cyst with degenerated epithelial lining.     

Gastric duplication cyst (gdc) associated with ectopic pancreas: Case report and review of the literature

IntroductionDuplication of the alimentary tract is a relatively rare congenital anomaly. It can affect any part of the gastrointestinal tract, with ileum being the most common site. These malformations are believed to be congenital, formed before the differentiation of epithelial lining, and therefore named for the organ with which they are associated. Duplication cysts of the stomach represent four percent of all alimentary tract duplications.Case reportHere, we report a rare case of symptomatic duplication cyst of stomach associated with ectopic pancreas presenting in adult.DiscussionGastrointestinal duplication is a relatively rare anomaly that may occur at any level from oral cavity to rectum with ileum being the most common site. Duplication cysts of the stomach are quite rare, and most of them have been reported in children. Duplication cysts of ileum are usually located on the mesenteric border, whereas the usual location for gastric duplication cysts is along the greater curvature. The duplication cyst is entirely separated from the adjacent bowel but shares a common wall. Complete removal is the treatment choice to avoid the risk of possible complications such as obstruction, torsion, perforation, hemorrhage, and malignancy. A non-communicating GDC is classically treated by complete excision of the cyst and resection of the shared wall between stomach and the duplication cyst.ConclusionThis unusual developmental anomaly should be included in the differential diagnosis of cystic masses of the gastrointestinal tract, and the possibility of malignancy should also be considered, so as be treated surgically by complete resection.     

Laparoscopic marsupialization of a giant posttraumatic splenic cyst.

BACKGROUND AND OBJECTIVE: Nonparasitic cysts are rare clinical lesions of the spleen. Causes include congenital malformations and trauma. Historically, management has entailed partial or total splenectomy using an open approach. Recently, laparoscopic approaches have been developed. In this report, we describe laparoscopic marsupialization of a giant splenic cyst (diameter > 15 cm). METHODS: A 25-year-old African-American man presented with a 9-month history of early satiety, constipation, and left upper quadrant pain. Additionally, he reported blunt trauma to the abdomen 2 years earlier. Physical examination revealed a large, fixed, nontender left upper quadrant mass. Computed tomography scan confirmed a simple cyst within the spleen, measuring 20 x 25 cm. Echinococcus and Entamoeba histolytica serologies were negative. Laparoscopic exploration was performed. Four liters of brown fluid were aspirated and intraoperative cytology confirmed a nonparasitic cyst. The cyst wall was excised and the cavity was packed with omentum. RESULTS: The patient's recovery was uneventful, and he was discharged to home tolerating a regular diet on postoperative day 3. At 6-month follow-up, the patient was asymptomatic and showed no evidence of recurrence. CONCLUSION: Nonparasitic splenic cysts are rare lesions. Laparoscopic marsupialization is safe and effective for giant nonparasitic splenic cysts and should be considered the treatment of choice.     

Obstructing ileal duplication cyst infected with Salmonella in a 2-year-old boy: a case report and review of the literature

Alimentary tract duplications (ATDs) are rare congenital anomalies, with an incidence of 1 in 4500 individuals. Patients with these lesions present in a variety of ways, and although histologically benign, ATDs can lead to lethal complications including volvulus, intussusception, or bowel obstruction. Irrespective of anatomical location, the epithelial lining of ATDs contains ectopic acid-secreting mucosa in more than 50% of cases, which can lead to ulceration, bleeding, or transmural erosion and perforation. We report an unusual case of a child who presented with small bowel obstruction caused by an ileal duplication cyst that had become infected with Salmonella. Although reports of infected mesenteric cysts and duodenal duplication cysts have been published, this is the first reported case of an infected ileal duplication cyst. We also present a review of the literature regarding these interesting lesions.     

Familial Epidermoid Cysts of the Spleen: Report of Two Cases

The familial occurrence of epidermoid cysts of the spleen is rare, with only six cases having ever been reported, to our knowledge. We recently diagnosed epidermoid cysts of the spleen in a mother and son. First, a 15-year-old boy was admitted to our hospital for management of blunt abdominal trauma. Computed tomography (CT) showed a ruptured large splenic cyst with an intraabdominal hematoma. We performed a splenectomy, and histopathological examination confirmed the existence of an epidermoid cyst of the spleen. About 2 years and 6 months later, the family physician found that the patient's 41-year-old mother had a large splenic cyst, and she was referred to our hospital for further investigation. CT showed a 10 × 8 cm cyst occupying most of the spleen. The patient underwent splenectomy, and a pathological diagnosis of an epidermoid cyst of the spleen was confirmed. Although the etiology of epidermoid cysts of the spleen is unclear, this familial occurrence may support the hypothesis of congenital malformation as a result of genetic change.     

Surgical experience with nonparasitic cysts of the liver —The characteristics and constituents of cyst fluid—

Fifteen patients with nonparasitic hepatic cysts underwent surgery to relieve abdominal complaints, at the First Surgical Department, Tokyo University Hospital between 1966 and 1989. Total removal of the cyst was carried out in 14 of the patients, while puncture and aspiration only were performed in the other patient in whom a cyst had ruptured spontaneously, after which hemoperitoneum was observed at emergency laparotomy. The size of the cysts varied from 7–19 cm with a mean of 12.4 cm. Histological study revealed a congenital cyst in 14 patients and a cystadenoma in one. The epithelium lining of the internal surface of the congenital cysts was highly atrophic and desolated and often disappeared. Examination of the cyst fluid revealed the same concentration of electrolytes as in the serum. Hepatic enzyme levels were usually lower than in the serum, but lactic dehydrogenase and aminotransferase levels were elevated in a few cases. Tumor marker levels of the cyst fluid were higher than those in the serum in four of five patients examined.     

Unilocular thymic cyst with ciliated respiratory epithelium as an unusual histological feature of thymic development abnormality

The result of the developmental abnormality of the third pharyngeal pouch, thymic cysts are very rare and classified as unilocular and multilocular. Unilocular thymic cysts are congenital and without inflammation and have small, thin walls filled with a brown fluid. The epithelial wall lining of unilocular cysts are commonly squamous, transitional, and either cuboidal or columnar. We herein present a rare case of a mediastinal unilocular thymic cyst coexisting with respiratory epithelium.     

Epidermoid cyst of the spleen,a case report

IntroductionSplenic tumors are rare and are either primary or secondary, benign or malignant. Most have none to minimal symptomatology and are found incidentally. Splenic cysts can be infectious, congenital, or traumatic. Epidermoid cysts and parasitic cysts are examples of primary cysts and usually have a classic presentation on imaging. Despite advanced imaging modalities and patient's clinical presentation, it can be difficult to diagnose an epidermoid cyst without histological examination. The purpose of this paper is to discuss typical findings of primary splenic cysts on imaging, but how they may differ in appearance.Presentation of case51 year old female who presented with vague abdominal discomfort and was found to have a large splenic mass with cystic components on imaging which did not demonstrate a typical primary splenic cyst appearance. Patient underwent an uneventful hand-assisted laparoscopic total splenectomy and had an uneventful recovery with histopathology revealing an epidermoid splenic cyst.ConclusionPrimary splenic cysts are difficult to diagnose and differentiate with imaging alone. They have a variable presentation and can present like as a cystic mass. It is important to include them in the differential diagnosis of splenic masses since histopathology is the final determinant of the diagnosis.     

Laparoscopic splenectomy for epithelial cyst of the spleen

Splenic cysts of all types are a relatively rare entity. The origin of epithelial cysts of the spleen is controversial, most probably congenital in origin. Generally, epithelial cysts of the spleen are asymptomatic and discovered incidentally. We present the case of a 40-year-old woman with a 3.5 cm splenic cyst diagnosed four years before. The cyst raised progressively in dimension, the actual size being of 6.5 cm. Computed tomography scan and magnetic resonance showed a central splenic cyst in close relations with main splenic vessels. An initial indication of partial splenectomy was established, eventually a total splenectomy being performed by laparoscopy due to close relations of the cyst with the main hilar splenic vessels. The hemostasis was assured with the aid of Ligasure Atlas 10 mm instrument. The pathology examination revealed a multilocular splenic cyst with a cuboidal epithelial lining. Central localization of splenic cysts represents an indication for total splenectomy. Laparoscopy provides a minimal access method of obtaining pathological confirmation of diagnosis, reduction of cyst complications, and a short hospital stay. This article discusses different aspects of epithelial cysts related to pathology, diagnostic and indications for operative treatment, a review of the literature being also presented.     

Ciliated hepatic foregut cyst

A male infant was found to have a large congenital hepatic cyst, first noted in late gestation by prenatal ultrasound scan. The cyst communicated with the biliary tree and was eventually removed completely by an extended right hepatectomy. Histopathologic examination showed a thick-walled, unilocular cyst lined predominantly by ciliated, stratified squamous epithelium with an outer wall composed of smooth muscle cells and fibrous tissue. These features are diagnostic of a ciliated hepatic foregut cyst, a rare congenital malformation with histologic similarities to bronchogenic cysts. The young age of our patient, prenatal detection, large size of the cyst, and a clear communication with the biliary tree have not been previously described with ciliated hepatic foregut cysts.     

Lateral cervical bronchogenic cyst: an unusual cause of a lump in the neck

BACKGROUND: Congenital cysts of the neck in children are not uncommon. Most of these are thyroglossal, branchial cleft, or less commonly, thymic cysts. Bronchial cysts rarely are initially seen as a neck mass. METHODS: Use of an illustrative case of a bronchogenic cyst initially seen as an upper lateral neck mass. CONCLUSIONS: We emphasize that although ectopic bronchogenic cysts are rare lesions of the head and neck, especially in the upper lateral neck, they should be included in the differential diagnosis in the evaluation of congenital neck cysts.     

Suprasternal bronchogenic cyst

Bronchogenic cysts are congenital anomalies that are typically found in the mediastinum or within the lung. Subcutaneous and cutaneous lesions are rare and most likely represent ectopic or displaced mesenchyme during early development. We report the presentation and results of resection of a suprasternal, subcutaneous bronchogenic cyst in a 23-month-old female infant that was successfully treated with simple excision.     

Giant epidermoid cyst of the spleen with carbohydrate and cancer antigen production managed laparoscopically

True cysts of the spleen are rare; in a few cases, high serum levels of carbohydrate and cancer antigen have been reported. In such instances, cyst resection or splenectomy is indicated to rule out malignant lesions and to remove the cancer antigen producing epithelium. We report the case of a young woman with a symptomatic giant epidermoid cyst of the spleen. Due to the secreting epithelium lining the cyst, serum levels of CA 19-9 and CA 125 were elevated. Laparoscopic splenectomy achieved symptoms relief and and long-term normalization of serum tumor markers.     

Intestinal Duplication Cyst Associated with Intestinal Malrotation Anomaly: Report of a Case

Duplications of the alimentary tract are rare congenital malformations and may occur anywhere in the intestinal tract. Intestinal duplication cysts have been rarely found with intestinal malrotation anomaly. We present a 2-year old boy who had intestinal duplication cyst, associated with intestinal malrotation anomaly.     

Congenital pancreatic cysts in children

The authors report a case of an 11-year-old girl with a solitary, congenital pancreatic cyst and review the literature. Such cysts are very rare and typically are diagnosed in childhood. As a neonate, this patient’s paternal half brother also had undergone resection of a congenital pancreatic cyst. The authors believe this is the first documented familial incidence of a congenital pancreatic cyst.     

Laparoscopic management of a ruptured giant epidermoid splenic cyst.

BACKGROUND: Epidermoid splenic cysts are uncommon lesions of the spleen. They are known to become symptomatic as a consequence of enlargement, infection, or rupture, the latter being an exceedingly rare complication traditionally treated with open splenectomy. We herein report a unique case of a giant epidermoid splenic cyst that ruptured spontaneously and was successfully treated with the laparoscopic approach. CONCLUSION: Laparoscopic surgery may be considered an initial treatment option in cases of very large epidermoid cysts even when rupture occurs.     

Lymphoepithelial cyst of the pancreas associated with elevated CA 19-9 levels

An extremely rare case of a lymphoepithelial cyst associated with persistent elevation of serum carbohydrate antigen (CA) 19-9 levels is described. A 72-year-old man was incidentally found to have a cystic tumor in the uncus of the pancreas and to have a high serum CA 19-9 level. At 2-year follow up, the tumor size had gradually increased and the high CA 19-9 level persisted. Because the malignant potential of the tumor could not be ruled out, a laparotomy was performed. The tumor was excised from the pancreas. On pathological examination, the tumor was proven to be a lymphoepithelial cyst. After the operation, the patient’s serum CA 19-9 level decreased to the normal range. Lymphoepithelial cysts of the pancreas are a rare, benign entity. They are true pancreatic cysts, characterized by a mature, keratinizing, squamous lining surrounded by lymphoid tissue. Because the treatment options and the prognosis of these entities are quite different from those of other cystic neoplasms of the pancreas, preoperative differential diagnosis is the main issue. Thus, although they are rare, lymphoepithelial cysts should be considered in the differential diagnosis of cystic tumors of the pancreas.     

A rare cause of root-compression: Subaxial cervical synovial cyst in association with congenital fusion

IntroductionSynovial cyst in the cervical spine is a very rare pathology that develops from the facet joint. When a synovial cyst emerges into the surrounding space, it can compress the nervous tissue and cause neurological symptoms. In the cervical area there is additionally the risk of spinal cord compression comparing to the more common presentation of synovial cysts in the lumbar spine.Presentation of caseHere, a cervical synovial cysts from the left facet joint grew into the spinal canal and compressed the C8 nerve root which led to root compressing symptoms. Interestingly we found this synovial cyst with congenital fusion. We identified only nine similar cases in the literature. The cyst was removed surgically and the patient discharged without complications.DiscussionNumerous theories have been established to explain the pathogenesis of synovial cyst. Biomechanical alterations of the spine play a significant role in the development of synovial cyst. However, the etiology is still unclear.ConclusionSurgical treatment should be considered in cervical synovial cysts with neurologic deficit or with cord compression or when the conservative treatment is ineffective.
