[A comparative study of three cases of neuronal intranuclear inclusion disease (NIID)].

All three patients were men in their 70s. All cases were solitary onset and the chief complaint was gait disturbance. All patients had miosis and limb and trunk ataxia, MMSE score was declined in two patients, and FAB score was declined in all patients. Head MRI showed leukoencephalopathy, cerebellar atrophy, and DWI high intensity signal in corticomedullary junction. However, two of the three patients were not followed up without further examination. Skin biopsies in all cases showed ubiquitin-positive and p62-positive intranuclear inclusions. Genetic testing showed CGG repeat expansion of NOTCH2NLC. The diagnosis of neuronal intranuclear inclusion disease (NIID) was made based on the above findings in all cases. Most patients are diagnosed with NIID due to memory loss, but sometimes they are diagnosed due to gait disturbance with ataxia. It is important to proceed with the diagnosis by skin biopsy and genetic diagnosis based on the characteristic MRI findings of the head.

[A Case of Giant Liver Metastasis from Gastric Cancer after Surgery for Which Transcatheter Arterial Embolization and Chemotherapy Made Hepatic Resection Possible].

The prognosis of liver metastasis from gastric cancer, which often exhibits incurable factors, is dismal, and no effective therapy exists. We report a case of giant liver metastasis from gastric cancer after surgery, for which transcatheter arterial embolism and chemotherapy(G-SOX)made it possible to perform hepatic resection. The patient was a 78-year-old woman who underwent distal gastrectomy combined with D2 lymphadenectomy at our department in August 2014. She complained of abdominal distension, and a liver metastasis measuring more than 16 cm in diameter was found on computed tomography in April 2015. Transcatheter arterial embolization was performed followed by chemotherapy(9 courses of G-SOX were administered). These therapies were effective, enabling partial hepatic resection to be performed. The patient remains alive and free from recurrence 4 months after surgery. Although no effective therapy exists for liver metastasis from gastric cancer, intensive therapies may enable curative resection.

[A case of adenosquamous gastric carcinoma successfully treated with TS-1, low-dose CDDP and docetaxel as neoadjuvant chemotherapy].

The patient was a 66-year-old male with extremely advanced gastric cancer type 3 and diagnosed with adenocarcinoma by endoscopic biopsies specimens. Combined chemotherapy of TS-1, CDDP and docetaxel was prescribed in order for tumor reduction and downstaging. TS-1 (80 mg/m(2)) was administered 28 days followed by 14 days rest as one course. CDDP (8 mg/m(2)) was administered on days 1, 2, 14 and 15 and docetaxel (40 mg/m(2)) was administered on day 1 and 14, followed by 4 weeks rest as one course. After 2 courses of treatment, a CT scan revealed a minor response of tumor reduction. Therefore, total gastrectomy, partial pancreas body and tail resection, and D 2 lymph node dissection were performed. The patient had undergone adjuvant chemotherapy of TS-1 and biweekly docetaxel after surgery with no recurrence for 13 months. Adverse reactions were grade 3 neutropenia and grade 2 diarrhea. Combined chemotherapy of TS-1, low-dose CDDP and docetaxel were intensive and required constant patient monitoring. However, it proved effective and feasible as a neoadjuvant chemotherapy regimen for advanced gastric cancer.

Carcinosarcoma of the submandibular gland: an autopsy case.

Malignant mixed tumors of salivary glands are classified as three types:carcinoma arising in a pleomorphic adenoma, the most common; benign metastasizing pleomorphic adenoma; and carcinosarcoma (true malignant mixed tumor), which is very rare [Ann. Otol. Rhinol. Laryngol. (1982) 91 342]. In carcinoma, both epithelial and soft tissue elements are malignant. In the context of previous reports, we discuss a case of carcinosarcoma of the submandibular gland including the results of postmortem examination.
