Abstract
RATIONALE Schwannoma is common in young and middle-aged people and occurs in the head, neck, posterior mediastinum, and retroperitoneal. Schwannoma, on the other hand, is a rare occurrence in the seminal vesicle. Early diagnosis and treatment are crucial since the disease can cause lower abdominal pain, nocturia, frequent urination, blood sperm, and other symptoms. There is no standard diagnostic or treatment guideline for seminal vesicle schwannomas currently. Therefore, the treatment experience relies on the few cases reported throughout the world. PATIENT CONCERNS A 45-year-old male patient discovered that the tumor beside the right side spermatophore is bigger than 3 years ago. DIAGNOSIS Schwannoma of seminal vesicle. INTERVENTIONS Ureter double-J tube implantation and laparoscopic surgery for schwannoma of seminal vesicle. OUTCOMES The operation process went smoothly. And the patient was no discomfort after half a year. CONCLUSION Schwannoma of the seminal vesicle is very rare in the clinic, and the imaging examination was not conclusive. The diagnosis mainly depends on pathological results. Surgical resection is the best treatment method for schwannoma. In surgery for schwannoma of seminal vesicle, combined with the ureter double-J tube implantation are many benefits. This case is an excellent example of the seminal vesicle schwannomas.

Abstract
Hepatic schwannoma is a very rare hepatic tumor, usually appearing as a hypervascular solid mass with or without various degrees of cystic changes; however, to the best of our knowledge, only the two cases of hepatic schwannoma showing a multi-cystic appearance have previously been reported. We report herein a benign hepatic schwannoma presenting as an unusually large multi-cystic mass. The gadoxetic acid disodium-enhanced magnetic resonance imaging features are described with the histopathologic correlation and briefly review the literature. The solid-like areas showing the early/progressive enhancement, reflecting remnants of the Antoni A/B portion, during the dynamic phases may be helpful imaging features for the differentiation of other multi-cystic hepatic lesions, but pathological evaluation remains essential for diagnosis.

Abstract
INTRODUCTION A hepatic schwannoma is extremely rare and difficult to diagnose preoperatively. PRESENTATION OF CASE We report the case of a 47-year-old male patient who was referred to our hospital for the close investigation of a hepatic tumor which had not been detected two years earlier. An enhanced computed tomography revealed a well-circumscribed and encapsulated tumor with a size of 50mm which was adjacent to the inferior vena cava (IVC) and the right hepatic vein. The tumor was heterogeneously enhanced until the equilibrium phase. A magnetic resonance image showed a hypointense area on a T1-weighted image and a hyperintense area on a T2-weighted image. These findings differed from those of common malignant hepatic tumors, such as hepatocellular carcinoma and colorectal liver metastases. The tumor was most likely a mucus-producing tumor or a liquefactive degenerated adenocarcinoma. Although we could not confirm an exact diagnosis of the tumor, we performed a surgical resection in view of the possibility of malignancy. The patient underwent a limited liver resection with resection of the IVC. Histologically, the tumor was diagnosed as a benign schwannoma comprised of Antoni A and B areas. The nuclear palisading formation of the tumor showed Verocay bodies. DISCUSSION 15 cases of hepatic schwannoma are reviewed to clarify the typical radiological features. The radiological findings of the present case were consistent with those of the hepatic schwannoma when considering retrospectively. CONCLUSION A precise preoperative diagnosis of hepatic schwannoma is difficult, and liver resection is recommended when a hepatic schwannoma is suspected.

Abstract
Hepatic schwannoma is a rare benign disease with a good prognosis. Early diagnosis is difficult due to the absence of specific clinical presentations and its rarity. The present study briefly described a 64-year-old female patient with hepatic schwannoma mimicking intrahepatic cholangiocarcinoma. Furthermore, the clinical data of 30 patients with hepatic schwannoma were also reviewed and analyzed. The mean age of the 30 patients was 51.7 years (range, 21-83 years) and ~2/3 were female. All patients in the benign group underwent surgical treatment and survived until the last follow-up, of whom 19 received complete resection and the remaining 1 underwent liver transplantation. However, in the malignant group, only three cases who underwent the surgical resection remained alive at last follow-up. Another seven cases were succumbed to mortality, 4 cases of whom had deteriorated to have no operation opportunity by the time they saw a doctor, and among the remaining three cases with hepatectomy, 1 died of liver dysfunction at 21 days postoperatively, 2 succumbed to recurrences at 18 and 23 months postoperatively. In conclusion, hepatic schwannoma is a rare benign disease with a good prognosis. However, once the malignant transformation occurs, the prognosis is not satisfied. Complete resection is the mainstay for cure and liver transplantation is often necessary.

Abstract
Malignant peripheral nerve sheath tumor (MPNST) of the liver is rare. Most cases of MPNST are accompanied by neurofibromatosis 1 (NF-1, von Recklinghausen's disease). We herein report an autopsy case of MPNST without NF-1 and review the pertinent literature. The tumor occupied the entire lobe of the liver, and was 18 cm in maximum diameter. The tumor revealed necrosis and cystic changes with hemorrhage and it had also metastasized to the peritoneum. Microscopically, the tumor was composed of pleomorphic spindle cells with hyperchromatic nuclei and mitogenic figures. The spindle cells stained positive for both S-100 and vimentin antibodies.

Abstract
A primary benign schwannoma of the liver is extremely rare and is difficult to preoperatively discriminate from a malignant tumor. We compared the imaging and pathological findings, and examined the possibility of preoperatively diagnosing a benign liver schwannoma. A 72-year-old woman was admitted to our hospital because of a 4.6-cm mass in the liver. A malignant tumor was suspected, and a right hepatectomy was performed. After this, the diagnosis of a primary benign schwannoma of the liver was made through pathological examination. Contrast-enhanced ultrasonography (CEUS) with Sonazoid showed minute blood flows into the septum and solid areas of the tumor in the vascular phase; most likely due to increased arterial flow associated with infiltration of chronic inflammatory cells. In the postvascular phase, CEUS showed contrast defect of cystic areas and delayed enhancement of solid areas; most likely due to aggregation of siderophores. Because discriminating between a benign and malignant schwannoma of the liver is difficult, surgery is generally recommended. However, the two key findings from CEUS may be useful in discriminating ancient schwannoma by recognizing the hemorrhage involved in the secondary degeneration and aggregation of siderophores.

Abstract
Schwannoma is predominantly a benign neoplasm of the Schwann cells in the neural sheath of the peripheral nerves. Occurrence of schwannoma in parenchymatous organs, such as liver, is extremely rare. A 64-year-old man without neurofibromatosis was observed to have a space-occupying lesion of 23mm diameter in the liver during follow-up examination for a previously resected gastrointestinal stromal tumor (GIST) in the small intestine. He underwent lateral segmentectomy of the liver under a provisional diagnosis of hepatic metastatic recurrence of the GIST. Histological examination confirmed the diagnosis of a benign schwannoma, confirmed by characteristic pathological findings and positive immunoreactions with the neurogenic marker S-100 protein, but negative for c-kit, or CD34. The tumor was the smallest among the reported cases. When the primary hepatic schwannoma is small in size, preoperative clinical diagnosis is difficult. Therefore, this disease should be listed as differential diagnosis for liver tumor with clinically benign characteristics.

Sarcomas originating from abdominal organs are extremely rare, and literature in which investigators focus on their imaging features is scarce. This article aims to review the computed tomography and magnetic resonance imaging features of these rare tumors and to help in clinical diagnosis. Various sarcomas (eg, angiosarcoma, undifferentiated embryonal sarcoma, leiomyosarcoma, carcinosarcoma, rhabdomyosarcoma) originating, respectively, from different abdominal visceral organs (liver, pancreas, spleen, kidney, adrenal gland, uterus, and prostate gland) are reviewed along with cases we encountered.

Abstract
INTRODUCTION Schwannomas are usually benign nerve sheath tumors, which typically arise in the head, neck, spinal cord and extremities. Schwannoma of the biliary tract is an extremely rare finding. Patients generally lack symptoms and seek medical attention when tumor growth causes obstructive jaundice. Preoperative diagnosis is difficult and resection is the treatment of choice. METHODS A 54 year-old female with history of back and right labia minor melanoma for which she underwent complete excision and right inguinal lymph node dissection more than 10 years ago, was evaluated for new onset gastroesophageal reflux symptoms and found to have markedly abnormal liver enzymes. Imagining studies revealed intrahepatic ductal dilatation and a 5.2 cm mass in the porta hepatis that was not consistent with cholangiocarcinoma or hepatocellular carcinoma. Multiple percutaneous biopsies of the mass failed to provide a definitive diagnosis. With a high clinical suspicion of metastatic melanoma and no other evident sites of disease, operative intervention was undertaken for diagnosis and definitive treatment. RESULTS Diagnostic laparoscopy was performed initially, but access to the mass was difficult, given its location. Subsequently, the patient underwent laparotomy, with tumor excision, common bile duct resection and hepato-jejunostomy. Pathologic examination and analysis were consistent with cellular schwannoma. Postoperatively, the patient recovered uneventfully, and liver function studies returned to normal. CONCLUSION Schwannomas are uncommon tumors, which very rarely arise from the biliary tract and cause biliary obstruction. Exploration is indicated in order to establish the diagnosis and to render definitive treatment.

Abstract
Primary angiosarcoma of the liver accounts for up to 2% of all primary liver tumors and is the second most common primary malignant neoplasm of the liver. Approximately 10 to 20 new cases are diagnosed every year in the United States and the prevalence varies from 0.14 to 0.25 per million. In an autopsy series from Chicago, one hepatic angiosarcoma was noted for every 30 cases of hepatocellular carcinoma.

Abstract
Two surgical cases of benign schwannoma of the liver were examined: A 64-year-old female who was admitted to hospital for the treatment of early gastric cancer (case 1) and a 69-year-old female who had pitting edema in the legs (case 2). Diagnostic imaging revealed large solid masses located in the caudate lobe through to the left lobe of the liver in case 1 and in the left lobe in case 2. Both patients showed no signs of von Recklinghausen's disease. Partial hepatectomies were performed and the maximum diameter of their resected hepatic tumors was 4 cm and 15 cm, respectively. Histologically, the well-demarcated tumors were yellowish in color, elastic-hard in consistency and consisted predominantly of short spindle-shaped cells proliferating in an interlacing fashion. The tumor lesions were separated by fibrous bands and surrounded by a lymphoid cuff. Immunohistochemically, the tumor cells were positive for S-100 protein. The tumors were diagnosed as benign hepatic schwannoma.
