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
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
CDX-014 is an antibody-drug conjugate directed against TIM-1, a surface marker highly expressed in renal cell carcinoma (RCC) and ovarian carcinoma. This phase I, first-in-human trial was conducted to evaluate the safety and preliminary activity of CDX-014 in patients with advanced refractory RCC,
We report the case of an 82 year-old Japanese man with a history of multiple heart surgeries who presented with nausea and loss of appetite. Laboratory tests showed elevated liver and biliary enzymes. Imaging showed a possible space-occupying lesion within a dilated bile duct. Endoscopic retrograde
The coexistence of signet-ring cell carcinoma and neuroendocrine tumors is very rare. We report a 57-year-old man who presented with a history of weight loss and nausea. Gastric mucosal biopsies obtained during gastrointestinal endoscopy revealed a gastric signet-ring cell carcinoma. The patient
Intraductal papillary-mucinous carcinoma of the pancreas has been reported with increasing frequency. We report a case with intraductal papillary-mucinous carcinoma of the pancreas and discuss surgical treatment and current imaging modalities. A case with intraductal papillary-mucinous carcinoma was
The compound CMB-401 is an immunoconjugate consisting of the monoclonal antibody (MAb) hCTM01 directed against polymorphic epithelial mucin covalently bound to the cytotoxic antibiotic calicheamicin by an amide linker. We evaluated CMB-401 as monotherapy for the treatment of recurrent
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
Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration (EBUS-TBNA) is a reliable and accurate method for the diagnosis of mediastinal metastases in patients with pulmonary and extrathoracic neoplasms. We report the cytopathologic findings of a case of metastatic signet-ring cell carcinoma
Ovarian mucinous cystadenomas are cystic neoplasms lined by mucin-producing epithelial cells. They are mostly benign (80%) and frequently asymptomatic at early stages. The average diameter of ovarian mucinous cystadenomas ranges from 15 to 30 cm. Herein, we report the case of a giant benign ovarian
A large cell neuroendocrine carcinoma (LCNEC) of the stomach is very rare. A 76-year-old Japanese man was admitted to our hospital because of epigastralgia and nausea. Endoscopy revealed 2 large tumors in the stomach. He did not have multiple endocrine neoplasia type I or Zollinger-Ellison syndrome.
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
