绝经后妇女尼尔雌醇治疗前后骨密度及骨代谢的变化

３０例绝经后妇女口服尼尔雌醇（ＣＥＥ３）,每２周２ｍｇ共１年。治疗前后均采用单光子吸收法（ＳＰＡ）进行桡骨骨密度（ＢＭＤ）测量,进行血骨钙素（ＢＧＰ）、血降钙素（ＣＴ）、血雌二醇（Ｅ２）、血卵泡刺激素（ＦＳＨ）及空腹尿钙／尿肌酐（Ｃａ／Ｃｒ）测定。结果显示ＣＥＥ３治疗１年后治疗组骨ＢＭＤ增加１．１％,而对照组下降３．３％;血ＢＧＰ显著下降（Ｐ＜０．０１）;尿Ｃａ／Ｃｒ下降。本文提示,ＣＥＥ３能降低骨转换率,有效防止绝经后妇女的骨质疏松

Mantle cell lymphoma with plasma cell differentiation

The differentiation of B lymphocytes into plasma cells (PCs) is an antigen-mediated process that largely depends on the interaction between B cells and regulatory factors in their microenvironment. Long-lived PCs are derived from activated B cells in the germinal center (GC), whereas PC differentiation from naive B cells occurs in the extrafollicular areas and the PCs are short-lived. Consequently, lymphomas arising from post-GC B cells often exhibit plasmacytic differentiation, whereas lymphomas arising from naive B cells less commonly show plasmacytic differentiation. Herein, we report 2 cases of mantle cell lymphoma (MCL) with clonal PC differentiation. Both cases presented with the typical cytologic features of MCL and were characterized by a nodular and mantle-zone growth pattern. Clusters of clonal PCs with monotypic kappa light chain expression were identified in the centers of the tumor nodules and within reactive GCs. FICTION (Fluorescence immunophenotyping and Interphase Cytogenetics as a Tool for the Investigation Of Neoplasms) analysis demonstrated the characteristic t(11;14)(q13;q32) in both the MCL cells and clonal PCs, indicating that both cell types were derived from the same B-cell clone. These findings indicate that the clonal PC differentiation may occur within GCs in some cases of MCL.

Renal cell carcinoma with non-islet cell tumor hypoglycemia

We report a case of an elderly gentleman with renal cell carcinoma presenting with the rare entity of non-islet cell tumor hypoglycemia (NICTH). Non-islet cell tumor hypoglycemia syndrome is caused by the tumor producing insulin-like growth factor II, causing hypoglycemia. The syndrome is most commonly associated with very large fibromas or fibrosarcomas.

Small cell squamous and mixed small cell squamous--small cell anaplastic carcinomas of the lung

Five patients are presented who had neoplasms which, by light microscopy and in two cases cytologically, appeared to be small cell anaplastic (polygonal and fusiform cell type) carcinomas of the lung. However, by electron microscopy, four of the carcinomas exhibited squamous characteristics including desmosomes and tonofilament bundles, and lacked demonstrable neurosecretory granules, suggesting that they were small cell squamous carcinomas. The fifth carcinoma contained cells with neurosecretory granules as well as cells demonstrating squamous differentiation. One patient died within 3 months of presentation. Three patients survived for approximately 18 months each; two received chemotherapy but one was treated by surgical resection alone. The fifth patient had a peripheral coin lesion which was treated by surgical resection only; he is alive without evidence of recurrent carcinoma 1 year after operation. We suggest that some carcinomas of the lung with the light-microscopic and cytologic appearance of small cell anaplastic carcinoma are actually small cell variants of squamous cell carcinoma and lack the characteristic neurosecretory granules of classic small cell carcinoma. The behavior of these tumors needs to be determined.
