[A case of gastric large cell neuroendocrine carcinoma (LCNEC) for whom chemotherapy of CDDP+CPT-11 proved very effective].

Large cell neuroendocrine carcinoma(LCNEC)is a relatively new category with biological behavior similar to small cell carcinoma. Thus, it is reportedly well treated by the same chemotherapy as for small cell carcinoma. We experienced a case of gastric large cell neuroendocrine carcinoma, treated very effectively by CDDP+CPT-11.

A case of tumor-forming pseudoangiomatous stromal hyperplasia of the breast.

Pseudoangiomatous stromal hyperplasia (PASH), characterized by the presence of slit-like spaces embedded in a hyalinized stroma, is sometimes observed during pathologic examination of breast-tissue specimens. Because tumor-forming PASH is rare, we report a case of a 41-year-old woman admitted to our hospital with a tumor in her left breast. Ultrasonography and aspiration biopsy cytology revealed a benign tumor.

[Non-ketotic hyperosmolar diabetic coma in neurosurgical cases; review of 7 cases].

Neurosurgical patients with non-ketotic hyperosmolar diabetic coma (NHC) in our institution were analysed retrospectively. Seven cases were diagnosed as NHC being 0.47% of the number of inpatients in the last 5 years.
