A 64-year-old woman with upper abdominal pain, nausea, and vomiting was admitted. The magnetic resonance imaging revealed marked dilation and "crowding" of the segment 4 bile ducts with an area suspicious for a stone or tumor. Ultrasonography-guided percutaneous transhepatic cholangiography revealed
BACKGROUND
Muncin-hypersecreting intraductal pancreatic neoplasms were first described in 1982 and have been observed in increasing numbers since. They are observed primarily by endoscopic retrograde cholangiopancreatography (ERCP) and are characterized by an intraductal papillary neoplasm that
The identification of vomit stains may be helpful for crime scene reconstruction. However, there is no specific and convenient method for identifying vomit stain. Therefore, to establish the procedure for forensic identification of vomit stains, we focused on four gastric mucosa-expressing proteins,
BACKGROUND
Only few case reports of mucinous cystic pancreatic neoplasm containing an undifferentiated carcinoma with osteoclast-like giant cells have been described in the literature. In the majority of cases this unusual association of tumors seems related to a favorable outcome. We present the
OBJECTIVE
We have performed a phase I study of the cytotoxic immunoconjugate CMB-401 in women with epithelial ovarian cancer (EOC). CMB-401 is a directed chemotherapy that comprises a genetically engineered human antibody against polymorphic epithelial mucin, to which is attached covalently two to
Pyloric duodenal stenosis is usually caused by pyloric, juxtapyloric or duodenal ulcer, or by postbulbar ulcer. Gallbladder cancer (GBC), duodenal diverticula, annular pancreas and superior mesenteric artery syndrome (Wilkie's syndrome) are rare causes of pyloric duodenal stenosis. The case of a
A 6-year-old Rottweiler was presented to the North Carolina State University College of Veterinary Medicine for evaluation of multiple cutaneous nodules. The dog had a history of anorexia, vomiting, and hind-limb paraplegia. Results of cytologic examination of the cutaneous nodules were consistent
An 8-year-old male Rottweiler was presented for recurrent episodes of dysphagia and vomiting with chronic weight loss. Radiography revealed a mediastinal mass in the heart base region. Necropsy revealed a firm, white mediastinal mass extending along the distal esophagus, through the diaphragm, to
Signet-ring cell type of gastric carcinoma can easily escape detection by the pathologist, and this confusion is compounded by the presence of morphologic patterns other than the conventional appearance. One such morphologic variant is composed of deeply eosinophilic cells containing minute
Colloid cysts account for approximately 2% of primary brain tumours and the majority of cases are identified in the fourth and fifth decade. They are small, gelatinous neoplasms lined by a single layer of mucin-secreting columnar epithelium that are thought to arise from errors in folding of the
The authors report a series of 10 low-grade neoplasms arising in the midline anteriorly in the region of the septum pellucidum with many of the histologic features of dysembryoplastic neuroepithelial tumor (DNT). The patients (five female, five male) ranged in age from 6 to 35 years (mean age, 21.5
Diffuse malignant peritoneal mesotheliomas in children are uncommon, aggressive tumors with a grave prognosis. We herein report the clinical, radiologic, and pathologic findings of a 16-year-old male. The adolescent presented with a history of abdominal pain, nausea and daily, nonbilious, nonbloody
A 21-year-old neutered female domestic shorthaired cat was presented with a history of inappetence, vomiting and haematuria. The cat was humanely destroyed at the owner's request and a necropsy examination was performed. A 0.8 × 0.5 × 0.5 cm mass was located in the left lobe of the pancreas. The
Between 1981 and 1997 seven children and adolescents (5 boys and 2 girls) were treated for colorectal carcinomas in two paediatric centres. The case notes of the patients were studied to determine the presentation, clinical findings, prognosis and the differences of colorectal carcinomas in the
A 63-year-old woman was admitted to our hospital with serious headache and vomiting. Five months before admission, she had undergone surgery for a primary advanced gastric cancer. Neuroradiological examinations revealed subdural fluid collection. We twice performed evacuation of the subdural fluid
