1/58. Spontaneous rupture of a nonparasitic liver cyst complicated by intracystic hemorrhage.a case of spontaneous rupture of simple liver cyst complicated by intracystic hemorrhage is described. This rare condition was detected in a 61-year-old man who underwent left trisegmentectomy of liver under a suspected diagnosis of cystadenocarcinoma because of elevated serum levels of carbohydrate antigen (CA) 19-9 and DUPAN 2, and the presence of an intracystic structure. The resected specimen showed a benign liver cyst with intracystic hematoma and high levels of CA19-9 and DUPAN 2 in the cystic fluid. It is suggested that cyst rupture may increase serum levels of tumor markers whose levels are high in the cystic fluid, and that repeated observations of an intracystic structure may be the most reliable method to distinguish intracystic hemorrhage from cystic neoplasm.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |

We describe a patient presenting with a testicular mass simulating a neoplasm, who proved to have a localized hemorrhagic infarction.- - - - - - - - - - ranking = 5keywords = neoplasm (Clic here for more details about this article) |
3/58. A case of hemorrhagic cyst of the pancreas resembling the cystic endometriosis.A 47-year-old Japanese woman with a history of epigastric pain and a recent episode of acute pancreatitis (back pain, nausea, and vomiting) and anemia was found to have a pancreatic cyst of the tail on CT-scan and ultrasonography. Especially, ultrasonography revealed the papillary solid lesion in the cyst. With the tentative diagnosis of a cystic neoplasm, distal pancreatectomy was performed. Histological examination of sections showed massive hemorrhage, surrounded fibrous connective tissue, and numerous macrophages with hemosiderin deposits; these histological findings resembled cystic endometriosis. The clinicopathological features and pathogenesis of the pancreatic endometrial cyst are discussed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
4/58. Pulmonary hemorrhage in a hemophiliac simulating a lung neoplasm.We report an elderly, male smoker with moderate hemophilia b who presented with hemoptysis. Chest imaging revealed a well-circumscribed, pulmonary, mass lesion. Repeated bronchoscopy failed to make a diagnosis, and the patient ultimately underwent open thoracotomy with resection of the mass. Pathologic examination revealed hemorrhagic changes in association with bullous lung disease. This is the first report of symptomatic pulmonary hemorrhage in a patient with hemophilia b. hemorrhage into a pre-existing bulla can simulate a primary lung neoplasm.- - - - - - - - - - ranking = 5keywords = neoplasm (Clic here for more details about this article) |
5/58. Intracystic hemorrhage of pancreatic serous cystadenoma after renal transplantation: report of a case.Immunosuppressive therapy after transplantation increases the risk of developing neoplasms, and neoplasms of the digestive organs are very common in asia. We experienced a patient with an intracystic hemorrhage of pancreatic serous cystadenoma during the follow-up after renal transplantation. Pancreatic cystadenomas are not frequent. Only two cases, presenting with acute abdomen, have so far been reported in the literature. The intracystic hemorrhage in our case may have been related to a rapid tumor growth due to weakened antitumor immunity and azathioprine-induced pancreatitis.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
6/58. Sudden hemorrhage of the breast caused by breast cancer: a case report and review of the literature.A rare case of sudden hemorrhage caused by breast cancer is reported. A 71-year-old woman noted bleeding from her left breast. physical examination of the left breast showed a localized open cavity accompanied by bleeding and coagulation. The patient had no history of breast trauma or anticoagulation therapy. Incisional biopsy followed by histological examination resulted in a diagnosis of granulation tissue with no cancer cells present. mammography and ultrasonography indicated probable breast cancer. As a result, a second incisional biopsy was performed, which suggested invasive ductal carcinoma without histological skin invasion. A modified radical mastectomy was performed under a diagnosis of stage II breast cancer. breast cancer with sudden hemorrhage is rare. We review the literature and discuss the cause of this unusual manifestation.- - - - - - - - - - ranking = 0.23267306353269keywords = ductal (Clic here for more details about this article) |
7/58. Tc-99m MIBG imaging in a huge clinically silent pheochromocytoma with cystic degeneration and massive hemorrhage.I-131 metaiodobenzylguanidine scintigraphy showed marked accumulation in the walls of a clinically silent, huge cystic adrenal mass with a prominent hemorrhage in a 48-year-old man. Although a careful reexamination of the histologic specimen finally lead to a diagnosis of pheochromocytoma, the appearances of this mass on computed tomography and magnetic resonance imaging were not specific for this neoplasm, and even pathologic analysis initially indicated, incorrectly, that this lesion was a hemorrhagic hemangioma. This case shows that I-131 metaiodobenzylguanidine scintigraphy is useful for correctly diagnosing an adrenal mass with prominent cystic or hemorrhagic degeneration.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
8/58. Haemorrhagic hepatic cyst: a differential diagnosis of cystic tumour.A 63-year-old man was found on ultrasound examination to have a hepatic cystic mass with a mural nodule, which was mildly enhanced on contrast enhanced CT and MRI. At surgery, the cystic fluid was haemorrhagic and histological examination of the mural nodule demonstrated an organized haematoma. This case is of interest in that an apparent mural nodule was present in a non-neoplastic cyst. Haemorrhagic hepatic cyst with an organized haematoma should be included in the differential diagnosis of cystic neoplasms.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
9/58. pancreatitis of unusual origin.The anatomic pattern seen in the three patients with contiguous gastric duplications associated with pancreatic ducts evidently predisposes the patient to pancreatitis. In the previous patient reported upon from this institution, the correlation of severe bleeding episodes with attacks of pancreatitis strongly supports the concept of blood blocking the pancreatic ductal system, thereby producing pancreatitis. Passage of viscous mucoid secretions from the aberrant gastric mucosa into the pancreatic ductal system also might retard the normal flow of pancreatic juice, producing elevation of the serum amylase level and pain. Overdistention of the gastric duplication also might be considered as a source of pain, but such mechanisms can be considered only speculation at present. diagnosis is usually made after more than one exploratory laparotomy. hemorrhage may result, should the gastric duplication contain parietal cells, leading to hemoductal pancreatitis, hematemesis or melena and anemia. At least one in five patients with a gastric duplication possesses another intestinal duplication. Developmental defects commonly are associated with gastric cysts. Almost identical anatomy was present in the patients with contiguous duplications. That two such rare pancreatic disorders were documented in the same institution within two years suggests that this pattern of developmental defect is more common that had previously been expected.- - - - - - - - - - ranking = 0.69801919059807keywords = ductal (Clic here for more details about this article) |
