A Rare Case of Melanotic Schwannoma Occurred Intraosseous of Sacrum: A Literature Review.

Background: Melanotic schwannoma is a rare tumor when it occurs in the sacrum. Though it is mostly classified as benign, the prognosis is unpredictable due to the possibility of recurrence and metastasis. Here, we reported a case of intraosseous of sacrum with good results and reviewed the literature.

Lymphadenitis associated with cat-scratch disease simulating a neoplasm: Imaging findings with histopathological associations.

The lymphadenitis associated with cat-scratch disease (CSD) is often confused with neoplasms by a number of radiologists and clinicians, and consequently, unnecessary invasive procedures or surgeries are performed. In the present study, the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) findings of 10 patients (6 men and 4 women) with clinically and pathologically confirmed lymphadenitis associated with CSD were retrospectively analyzed (CT in 3 patients, MRI in 6 patients, and CT and MRI in 1 patient) at The Second Affiliated Hospital of Zhejiang University School of Medicine (Hangzhou, China) between January 2007 and November 2014. As a result, 17 enlarged lymph nodes were identified in 10 cases.

Contrast-enhanced multiple-phase imaging features of intrahepatic mass-forming cholangiocarcinoma and hepatocellular carcinoma with cirrhosis: A comparative study.

The intrahepatic mass-forming cholangiocarcinoma (IMCC) is frequently misdiagnosed as hepatocellular carcinoma (HCC) in patients with cirrhosis, by numerous radiologists and clinical doctors, which results in the incorrect therapeutic treatment. A retrospective case-control study was conducted, and the contrast-enhanced multiple-phase (CEMP) computed tomography (CT) and magnetic resonance imaging (MRI) findings of 22 pathologically confirmed IMCC patients and 22 HCC controls with underlying liver cirrhosis were analyzed at the present hospital, from January 2010 to December 2015. In addition, serum tests were conducted and clinical symptoms of patients evaluated.

Differential CT and MR imaging diagnosis between low- and high-grade malignant vascular tumors of bone.

Objective: To investigate the CT and MR imaging findings and differential diagnosis of malignant vascular tumors of bone.

Materials And Methods: CT and MR imaging findings of 18 patients with histopathology-proven malignant vascular tumors of bone were examined. Assessed image features included age, sex, location, CT findings, and MR imaging appearances and dynamic contrast-enhanced MR imaging.

Epithelioid hemangioma of bone: a report of two special cases and a literature review.

Intraosseous epithelioid hemangioma (EH) is a rare intermediate vascular neoplasm, characterized by locally aggressive and rarely metastasizing behavior. Occasionally, EH of bone can behave strangely and may simulate malignant neoplasm. Here, we report two cases of EH of bone.

Multiple-phase spiral CT findings of pancreatic vasoactive intestinal peptide-secreting tumor: A case report.

The present study reports a case of pancreatic vasoactive intestinal peptide-secreting tumor (VIPoma), of 2.2 cm in diameter, arising from the region of the uncus of the pancreas with liver metastases in a 50-year-old patient, which demonstrated unusual multiple-phase spiral computed tomography (MPSCT) results. The pancreatic lesion was isodense compared with the pancreatic parenchyma.

Hemolymphangioma: a rare differential diagnosis of cystic-solid or cystic tumors of the pancreas.

We report a case of pancreatic hemolymphangioma. Hemolymphangioma is a malformation of both lymphatic vessels and blood vessels. The incidence of this disease in the pancreas is extremely rare.

Contrast-enhanced multiple-phase imaging features in hepatic epithelioid hemangioendothelioma.

Aim: To investigate and review the contrast-enhanced multiple-phase computed tomography (CEMP CT) and magnetic resonance imaging (MRI) findings in patients with pathologically confirmed hepatic epithelioid hemangioendothelioma (HEHE).

Methods: Findings from imaging examinations in 8 patients (5 women and 3 men) with pathologically confirmed HEHE were retrospectively reviewed (CT images obtained from 7 patients and MR images obtained from 6 patients). The age of presentation varied from 27 years to 60 years (average age 39.

Gastric duplication cyst lined by pseudostratified columnar ciliated epithelium: a case report and literature review.

Gastric duplication cyst (GDC) lined by pseudostratified columnar ciliated epithelium (PCCE) is an uncommon lesion stemming from a foregut developmental malformation. Its clinical and radiological presentation is usually nonspecific. In this study, we reported a 76-year-old man who presented with an incidentally found perigastric mass.

Pancreatic somatostatinoma with obscure inhibitory syndrome and mixed pathological pattern.

Somatostatinoma is a very rare neuroendocrine tumor that originates from D cells and accounts for less than 1% of all gastrointestinal endocrine tumors. The duodenum is the most frequent site for this tumor, followed by the pancreas. We here describe a 46-year-old Chinese woman who developed pancreatic somatostatinoma presenting with the characteristic "inhibitory" syndrome, but the symptoms were obscure and seemingly uncorrelated.

Estrogen receptor expression in adrenocortical carcinoma.

Objective: Adrenocortical carcinoma (ACC) is a rare but highly malignant tumor, and its diagnosis is mostly delayed and prognosis is poor. We report estrogen receptor (ER) expression in this tumor and our clinical experiences with 17 ACC cases.

Methods: The data of the 17 patients (9 females and 8 males, age range from 16 to 69 years, mean age of 42.

[Oncocytic carcinoid tumor of the lung: clinical and pathological characteristics].

Objective: To describe the clinical and pathological characteristics and the differential diagnosis of oncocytic carcinoid tumor of the lung (OCTL).

Methods: The histopathological and immunochemical changes of 3 cases of OCTL were studied, and the clinical data and related literature were reviewed.

Results: The 3 patients were all males, aged 32 - 73 years.

Protective effect of salvianolic acid B on chronic pancreatitis induced by trinitrobenzene sulfonic acid solution in rats.

Objectives: To investigate the effects of salvianolic acid B (Sal-B) on pancreatic damage in experimental chronic pancreatitis.

Methods: Chronic pancreatitis was induced by infusion of trinitrobenzene sulfonic acid into the pancreatic duct in male Sprague-Dawley rats. From the beginning of 5 weeks, the rats in group 2 were treated with Sal-B by gavage for 8 weeks.

Ascorbic acid alleviates pancreatic damage induced by dibutyltin dichloride (DBTC) in rats.

Purpose: Because previous studies have reported depleted antioxidant capacity in patients with chronic pancreatitis (CP), prevention of free radical production has gained importance in antifibrotic treatment strategies for CP. The aim of this study was to investigate the effects of ascorbic acid on oxidative capacity and pancreatic damage in experimental CP.

Materials And Methods: CP was induced in male Sprague-Dawley rats by infusion of dibutyltin dichloride (DBTC) into the tail vein.
