Abstract Background Mucinous cystic neoplasm of the Liver is rare tumors with malignant potential that occur in the biliary epithelium. Because of its rare presentation, it is often misdiagnosed before surgery. Case presentation A 63-year-old female patient presented with intermittent upper abdominal pain for three months. Laparoscopic hepatectomy of Segment 7 was conducted based on the preoperative diagnosis of space-occupying lesion in the right lobe of the liver. Postoperative pathology showed a low-grade mucinous cystic neoplasm in the right posterior lobe of the liver. The preoperative CA19-9 level was significantly increased while the postoperative CA19-9 returned to the normal range. Conclusions The diagnosis of mucinous cystic neoplasm of the liver is closely related to the thickening of the cystic wall or the increase of CA19-9, which has great significance and deserves clinical attention.

Abstract Background Mucinous cyst neoplasm of the liver (MCN-L) comprise less than 5% of all cystic liver lesions and is characterized by the presence of ovarian stroma and absence of bile duct communication. Case presentation Here, we discuss a 45-year-old woman who presented with symptomatic liver mass. Diagnostic workup detected a 4.2 × 3.6 cm septate cyst located in segments I, V, and VIII of the liver in communication with the right hepatic duct. An open right liver resection with total bile duct excision and hilar lymphadenectomy was performed. Pathology revealed a multiloculated cyst with lined mucinous epithelium and ovarian-like stroma, consistent with low-grade MCN-L. Conclusions This case shows that unusual location and bile duct communication can be present in MCN-L.

Abstract Background Emphysematous pyelonephritis (EPN) with gas in the inferior vena cava (IVC) is a rare presentation and to our knowledge, this is the first case report in the urologic literature. Case presentation A 35-Year-old obese diabetic Hispanic female presented to the emergency room with a clinical picture of septic shock. Prompt computerized tomography scan revealed EPN with gas throughout the right renal parenchyma and extending to the right renal vein, IVC, and pulmonary artery. She died before surgical intervention Conclusion This case demonstrates that patients presenting with severe EPN have a high mortality risk and providers should acknowledge that septic shock, endogenous air emboli, or a combination of both could result in cardiovascular collapse and sudden death.

Abstract Background Laparoscopic cholecystectomy is a well-established surgical procedure and is one of the most commonly performed gastroenterological surgeries. Therefore, strategy for the management of rare anomalous cystic ducts should be determined. Case presentation A 56-year-old woman was admitted to our hospital owing to upper abdominal pain and diagnosed with acute cholecystitis. Magnetic resonance cholangiopancreatography suspected that several small stones in gallbladder and the right hepatic duct drained into the cystic duct. Endoscopic retrograde cholangiopancreatography confirmed the cystic duct anomaly, and an endoscopic nasobiliary drainage catheter (ENBD) was placed at the right hepatic duct preoperatively. Intraoperative cholangiography with ENBD confirmed the place of division in the gallbladder, and laparoscopic subtotal cholecystectomy was safely performed. Conclusions The present case exhibited rare right hepatic duct anomaly draining into the cystic duct, which might have caused biliary tract disorientation and bile duct injury (BDI) intraoperatively. Any surgical technique without awareness of this anomaly preoperatively might insufficiently prevent BDI, and preoperative ENBD would facilitate safe and successful surgery.

Primary liver sarcomas represent a rare group of neoplasias, with angiosarcoma being the most common histological type. Primitive neuroectodermal tumor (PNET) represents a high malignant neoplasia that usually affects the central nervous system and soft tissues. An 18-year-old male patient was admitted with clinical complains of pain in the right upper abdominal quadrant. The clinical evaluation revealed a solid mass in the right hepatic lobe. On the gross examination of the resected liver specimen, the right lobe of the liver was replaced by a yellow-red solid mass measuring 21 cm in its largest dimension. On the histopathology, a tumor composed of small round blue cells with little cytoplasm and round nuclei was identified. The lesion revealed positive immunoexpression for vimentin and CD99 and negative immunostaining for desmin, CD45, cytokeratin, and neuroblastoma protein, suggesting, then, the diagnosis of PNET. Although it is an unusual tumor, it should be considered in the differential diagnosis of liver masses, especially in young patients.

Mucinous Cystic Neoplasms

Abstract Pancreatic mucinous cystic neoplasm (MCN) harbors two histological components, tumor epithelia and ovarian-like stroma (OLS). To examine the tumorigenesis of pancreatic MCNs, this study analyzed the distribution, amount, immunohistochemical phenotype, presence of theca cells of the OLS, and the alteration of tumor epithelium of 29 surgically resected MCN cases and compared them with tumor sizes. Non-mucinous type epithelium was present in all low-grade MCNs but its ratio decreased with tumor size (p < 0.05), suggesting that epithelial mucinous changes are a progression phenomenon. The intralobular distribution of OLS was observed in 27.6 % of MCN cases and its existence related to a smaller size (p< 0.05), suggesting intralobular generation of MCNs. Nuclear expression of β-catenin was observed for OLS of everywhere, suggesting consistent activation of the Wnt pathway for OLS. Three MCN cases (10.3%) contained a-smooth muscle actin (SMA)-negative OLS, where OLS surrounding dilated pancreatic ducts or MCN cysts were a-SMA-positive and otherwise negative, suggesting that a-SMA-positivity is an acquired phenomenon of OLS. With this study, we could hypothesize that pancreatic MCNs may generate intralobularly. Epithelial mucinous change and a-SMA-positivity of OLS may be progression phenomena. This is the first study to show the intralobular distribution of OLS.

Pulmonary Hydatid Cyst

Introduction. Hydatidosis is a parasitic manifestation caused by Echinococcus granulosus. It is characterized by cystic lesions in the liver and lungs. Diagnosis is based on typical history and radiological measures. Case presentation. A four-year-old boy presented with a one-year history of dry cough and difficulty in breathing which was of gradual progression. Computed tomography of the chest revealed a large 11.7 cm×8.6 cm×11.0 cm cyst in the right hemithorax. The patient underwent thoracotomy and recovered well post procedure. Conclusion. This case report highlights that large hydatid cysts can be surgically removed with good outcome and the importance of realizing that the disease is a burden to the public health and is much neglected.

Human hydatid disease is a significant health problem in endemic regions caused by the larval form ofEchinococcus granulosus. In this paper, we report a case of liver hydatid cyst. The patient, a 15-year-old boy, presented with a history of intermittent upper abdominal pain of a few-month duration was referred to our hospital for investigation. Computed tomographic scan and laboratory test suggested a hydatid cyst in the right lobe of liver. The adventitia resection of hydatid cyst was smoothly performed as there was a less bloody virtual space between adventitia and outer membrane. Our diagnosis was made using an imaging approach and was confirmed during surgery. We proposed the adventitia resection of hydatid cyst could be safe and easy to perform with low risk of bleeding and bile leakage.

Abstract A 35-year-old woman was referred for a symptomatic liver mass. Diagnostic workup detected a septated cyst located centrally in the liver measuring 10 × 7 cm. The cyst had gradually increased in size from previous studies with new intrahepatic biliary dilation. Due to concern for malignancy and symptomatic presentation of the patient, a partial central hepatectomy was performed. Pathology revealed a smooth-walled, multiloculated cyst lined with mucinous epithelium and ovarian-type stroma. The diagnosis of low-grade mucinous cystic neoplasm of the liver (MCN-L) was made. Characteristics of MCN-L have not been elucidated due to its rarity.

Ollier's Disease

Abstract We present a 24-year-old patient with multiple chondromas of both hands, the pelvis, the left leg, and an associated brain stem glioma. There was no evidence of hemangioma or dyschromia. and the condition was diagnosed as Ollier's disease, a special type of dyschondroplasia like Maffucci's syndrome and Kast's disease. An increased overall risk for development of malignant skeletal and nonskeletal tumors is associated with Maffucci's syndrome. The risk of malignant degeneration is lower in Ollier's disease. A glioma in the pons and the right lobe of the cerebellum was found in this patient. The literature describes an association with gliomas in only 12 cases of dyschondroplasia and an infratentorial localization in just one case. Signs of malignancy were histologically confirmed in 7 cases without significant preponderance of any one type. Our patient had a low-grade brain stem astrocytoma with fibrillar and gemistocytic components. A stereotactic serial biopsy made it possible to rule out malignant degeneration. Stereotactic brain tumor biopsy as a routine neurosurgical procedure is particularly valuable for deep space-occupying processes and forms the basis for therapy. In the present case, irradiation was not recommended.

The etiology of hepatic rupture is usually secondary to trauma, and hepatic rupture induced by spontaneous intrahepatic hematoma is clinically rare. We describe here a 61-year-old female patient who was transferred to our hospital with hepatic rupture induced by spontaneous intrahepatic hematoma. The patient had no history of trauma and had a history of systemic lupus erythematosus for five years, taking a daily dose of 5 mg prednisone for treatment. The patients experienced durative blunt acute right upper abdominal pain one day after satiation, which aggravated in two hours, accompanied by dizziness and sweating. Preoperative diagnosis was rupture of the liver mass. Laparotomy revealed 2500 mL fluid consisting of a mixture of blood and clot in the peritoneal cavity. A 3.5 cm × 2.5 cm rupture was discovered on the hepatic caudate lobe near the vena cava with active arterial bleeding, and a 5  × 6 cm hematoma was reached on the right posterior lobe of the liver. Abdominal computed tomography (CT) and laparotomy revealed spontaneous rupture of intrahepatic hematoma with hemorrhagic shock. The patient was successfully managed by suturing the rupture of the hepatic caudate lobe and clearing part of the hematoma. The postoperative course was uneventful, and the patient was discharged after two weeks of hospitalization.
