The coexistence of myelolipoma within adrenal cortical adenoma is extremely rare,for both tumors present usually as separate entities.There are only 16 such cases reported worldwide.To the best of our knowledge,the case we reported here is the first one of myxoid adrenal cortical adenoma associated with myelolipoma reported.A 32-year-old Chinese woman with 4-year history of hypertension was presented in our study.Computed tomography(CT)of the abdomen showed a large heterogene- ously-enhancing mass(4.5 cm in diameter)in the left suprarenal region.Clinical history and laboratory results suggest a metabolic disorder as Conn's syndrome.The patient underwent a left adrenalectomy,and a histopathological study confirmed the mass to be a myxoid adrenal cortical adenoma containing myelolipoma.The patient was postoperatively well and discharged uneventfully.In the present case report,we also discuss the etiology of simultaneous myelolipoma and adrenal adenoma associated with Conn's syndrome,and the methods of the diagnosis and differential diagnosis. 展开更多

Sclerosing epithelioid fibrosarcoma (SEF) is a rare and distinct variant of fibrosarcoma, composed of epithelioid tumor cells arranged in strands, nests, cords, or sheets embedded within a sclerotic collagenous matrix. We report a 39-year-old man with SEF of the liver, which infiltrated the inferior vena cava (IVC). The SEF of the liver was successfully resected, and the infiltrated IVC was also removed together with the liver tumor. Histopathological examination of the tumor showed typical histopathology of SEE Immunohistochemically, the tumor was positive for vimentin. Recurrence was noted 7 mo after surgery. After chemotherapy, the recurrent tumor was resected surgically, and histopathological examination showed similar findings to those of the primary tumor. To our knowledge, this is the first report of SEF of the liver with tumor invasion of the IVC. 展开更多

The histopathological diagnosis of gastric mucosal biopsy and endoscopic mucosal resection/endoscopic submucosal dissection specimens is important,but the diagnostic criteria,terminology,and grading system are not the same in the East and West.A structurally invasive focus is necessary to diagnose carcinoma for most Western pathologists,but Japanese pathologists make a diagnosis of cancer based on severe dysplastic cytologic atypia irrespective of the presence of invasion.Although the Vienna classification was introduced to reduce diagnostic discrepancies,it has been difficult to adopt due to different concepts for gastric epithelial neoplastic lesions.Korean pathologists experience much difficulty making a diagnosis because we are influenced by Japanese pathologists as well as Western medicine.Japan is geographically close to Korea,and academic exchanges are active.Additionally,Korean doctors are familiar with Western style medical terminology.As a result,the terminology,definitions,and diagnostic criteria for gastric intraepithelial neoplasia are very heterogeneous in Korea.To solve this problem,the Gastrointestinal Pathology Study Group of the Korean Society of Pathologists has made an effort and has suggested guidelines for differential diagnosis:(1) a diagnosis of carcinoma is based on invasion;(2) the most important characteristic of low grade dysplasia is the architectural pattern such as regular distribution of crypts without severe branching,budding,or marked glandular crowding;(3) if nuclear pseudostratification occupies more than the basal half of the cryptal cells in three or more adjacent crypts,the lesion is considered high grade dysplasia;(4) if severe cytologic atypia is present,careful inspection for invasive foci is necessary,because the risk for invasion is very high;and(5) other structural or nuclear atypia should be evaluated to make a final decision such as cribriform pattern,papillae,ridges,vesicular nuclei,high nuclear/cytoplasmic ratio,loss of nuclear polarity,thick and irregular nuclear membrane,and nucleoli. 展开更多

To identify gene expression profiling in epithelial ovarian cancer and to explore its correlation with histopathology characterization and prognosis.Gene expression profiles were generated from 10 hu- man ovarian frozen tissue specimens using Agilent Human 1A microarrays.Strikingly.clear differences of gene expression patterns were observed in ovarian cancer as compared to normal tissues.Unique gene pro files were observed in moderately and poorly differentiated epithelial ovarian cancer.It is concluded that different histopathology characterization likely exists extensive molecular heterogeneity. 展开更多
