We presented an unusual case with coexistence of carcinoid, signet-ring cell carcinoma (SRC) and heterotopic pancreatic tissue in stomach. Gastroscopic examination of this 63-year-old male patient showed multiple protrusions in gastric corpus near the greater curvature, identified by subsequent biopsy as carcinoid, Distal subtotal gastrectomy was performed, Histological and immunohistochemical examinations showed a carcinoid tumor in gastric corpus near the greater curvature, an intramucosal SRC at the lesser curvature of corpus and heterotopic pancreatic tissue in muscularis propria of the antrum at the lesser curvature with hyperplasia of peripheral endocrine cells producing multiple pancreatic hormones, We reviewed the literatures on clinicopathological characteristics and the differential diagnosis of the above three abnormalities, and concluded that the carcinoid in corpus near the greater curvature and SRC in the lesser curvature are independent lesions; the loci of endocrine cells in the muscularis propria and serosa are hyperplastic lesions from the heterotopic pancreatic tissue, rather than dissemination of carcinoid in corpus. 展开更多

Although gastric tumors have overlapping radiologic appearances, some unusual tumors may present specific imaging features. Using multidetector computed tomography(MDCT), with water as a negative oral contrast agent and intravenous contrast medium, can provide critical information for the diagnosis of gastric diseases. In addition, MDCT can evaluate the involvement of the gastric wall and extragastric extent of the disease, as compared with gastroenteroscopy and double-contrast upper gastrointestinal study. Regarding lesion location and size, enhancing and growth patterns, presence of calcification or fat, and involvement of the gastric wall and adjacent structures, CT may provide useful information. In this review article, we review the relevant literature and discuss the CT features and the histopathologic findings of different types of gastric lesions. The lesions are divided into benign(glomus tumors, schwannomas, leiomyomas, and lipomas), malignant(gastrointestinal stromal tumors, mucinous carcinomas, lymphomas, and carcinoid tumors), and tumor-like lesions(ectopic pancreas and bezoar). Familiarity with imaging appearances and pathologic findings can help physicians make an accurate diagnosis. 展开更多

A 79-year-old woman was admitted to our hospital with narrowing of the stools. We performed colonoscopy, computed tomography and positron emission tomography, which disclosed sigmoid colon cancer with IMV tumor embolism. She underwent sigmoidectomy and lymph node dissection. The tumor was diagnosed as endocrine cell carcinoma (type 4, pSS, med, INFa, v3, n1, stage Ⅲb). Immunohistochemically, chromographin A, synaptophysin, cytokeratin 20 and mucicarmine showed partial staining, and CD56 was totally reactive. Three months after operation multiple liver metastases appeared. She was treated with chemotherapy of cisplatin (CDDP) + irinotecan (CPT11). This case highlights the aggressiveness of endocrine cell carcinoma with tumor embolism, and it is essential to establish an accurate diagnosis and effective treatment. 展开更多

Introduction Choroid plexus papilloma (CPP) is a relatively rare, slow-growing benign tumor (WHO level I). Recently, an adult patient with fourth ventricle choroid plexus papilloma received surgery via a suboc- cipital midline approach in our hospital. It has been rare in clinical practice to see postoperative hemorrhage occurring in the same patient 3 times. The causes of the hemorrhage were analyzed based on literature regarding postoperative hemorrhage in choroid plexus papilloma and in intracranial tumors. The case involved in our study is described and detailed in the following. 展开更多

Spontaneous tumor regression has been subject of numerous studies and speculations for many years. This phenomenon is exceptional, but well reported, in some types of tumors, but not in pancreatic cancer. Pancreatic cancer has the worst five-year survival rate of any cancer. Despite numerous molecular studies and clinical approaches, using several mouse models, this cancer responds poorly to the existing chemotherapeutic agents and progress on treatment remains elusive. Although pancreatic cancer tumors seldom undergo spontaneous regression, and some authors take that with skepticism, there are some cases reported in the literature. However, the variability in the description of the reports and technical details could make this process susceptible to misdiagnosis. Distinguishing between different types of pancreatic carcinoma should be taken with caution as they have wide differences in malignant potential. Diseases such as pancreatic benign tumors, insulinomas, or autoimmune pancreatitis could be responsible for this misdiagnosis as a pancreatic cancer. Here we review different cases reported, their clinical characteristics, and possible mechanisms leading to spontaneous regression of pancreatic cancer. We also discuss the possibilities of misdiagnosis. 展开更多

Objective: To evaluate the clinical significance of platelet (PLT) count in epithelial ovarian cancer, and to investigate the correlation between thrombocytosis and the incidence of epithelial ovarian cancer. Methods: We evaluated 220 epithelial ovarian tumor patients divided into early stage epithelial ovarian cancer group (n = 80), advanced stage epithelial ovarian cancer group (n = 50) and benign ovarian tumor group (n = 90) as controls, who underwent primary surgical treatment. Three groups were evaluated with the relationship between platelet counts and preoperative and postoperative CA125, histopathology, abdominal edema, residual tumor, and lymph node metastasis. Epithelial ovarian cancer patients were evaluated whether platelet count was decreased after surgery. Results: The mean platelet counts were (234.55 ± 71.51)× 10^9/L in the early stage epithelial ovarian cancer group, (308.12±111.95)× 10^9/L in the advanced stage epithelial ovarian cancer group, and (206.28± 52.62) × 10^9/L in the benign ovarian tumor group, with a significant difference among the 3 groups (P 〈 0.05). In the early stage epithelial ovarian cancer group, the platelet count was correlated with histopathology. In the advanced stage epithelial ovarian cancer group, there was a correlation between thrombocytosis and the incidence of that residual tumor diameter was greater than 2 cm. But there was no relationship between platelet count and histopathology, CA125, abdominal edema, or lymph node metastasis. In general the platelet count was decreased after surgery. Conclusion: An increased platelet count is commonly seen in patients with epithelial ovarian cancer, but it usually decreases after surgery. Patients with thrombocytosis have poor prognosis. Platelet count can be used as a marker for the development and prognosis of epithelial ovarian cancer. 展开更多
