Disseminated Carcinomatosis of Bone Marrow as the Initial Presentation of Intrahepatic Cholangiocarcinoma without Jaundice: An Autopsy Case Report.

Disseminated carcinomatosis of the bone marrow (DCBM) is often accompanied by disseminated intravascular coagulation (DIC) and has a poor prognosis. DCBM develops most frequently in gastric cancer and is rarely associated with intrahepatic cholangiocarcinoma. A 41-year-old man was incidentally found to have DIC on his regular visit for ulcerative colitis and was diagnosed with DCBM with intrahepatic cholangiocarcinoma.

Effectiveness of Imatinib Mesylate Treatment in a Patient with Dermatofibrosarcoma Protuberans with Pulmonary and Pancreatic Metastases.

We herein encountered a case of abdominal wall dermatofibrosarcoma protuberans (DFSP) that developed pulmonary and pancreatic metastases 5 years after complete resection. Because specific rearrangements of the platelet-derived growth factor beta (PDGFB) locus by a novel fluorescence in situ hybridization method was detected, the patient was treated with imatinib mesylate at 400 mg/day. A partial response was achieved by imatinib without any specific toxicity.

Helicobacter pylori-negative Differentiated Adenocarcinoma of the Stomach.

A 58-year-old Japanese man was diagnosed with differentiated adenocarcinoma of the stomach. Histological findings of the resected specimen revealed well- to moderately-differentiated tubular adenocarcinoma (tub1, tub2), 13 mm in diameter, which invaded into the submucosa (SM1, 300 μm) and lymphovascular lumen (ly1). Serum antibody against Helicobacter pylori (Hp) and the (13)C-urea breath test were negative, and there were no atrophic changes in the tumor-adjacent mucosa.

Successful treatment of crizotinib-induced dysgeusia by switching to alectinib in ALK-positive non-small cell lung cancer.

We describe a case of dysgeusia that developed gradually over one week after initiation of crizotinib administration for treatment of ALK-positive non-small cell lung cancer, necessitating discontinuation of the agent. The symptom was accompanied by progressive loss in appetite and body weight. Alectinib, a novel alternative ALK inhibitor, was administered and has been successfully continued without any toxicity, including dysgeusia.

[A case of metachronous invasive ductal carcinoma concomitant with intraductal papillary-mucinous neoplasm (IPMN) of the pancreas, which could not be detected in contrast-enhanced CT scan performed 3 months ago].

A 61-year-old man had been followed up in another hospital under diagnosis of branch duct type IPMN for 4 years. Contrast-enhanced CT scan for regular check performed 3 months ago revealed no increase of IPMN and no pancreatic tumor. However, he complained of back pain after that, MRI was performed.
