RESUMEN
<p><b>OBJECTIVE</b>To study the clinical and pathological characteristics of solitary fibrous tumor (SFT).</p><p><b>METHODS</b>Clinical pathological analysis and immunohistochemical studies were performed on ten patients with SFT.</p><p><b>RESULTS</b>The SFTs located variously and showed different histological features. All cases showed positive staining for CD(34), VM (vimentin) and Bcl-2, but negative staining for Desmin, S-100, CK (cytokeratin) and EMA (epithelial membrane antigen).</p><p><b>CONCLUSIONS</b>SFT is described as a "patternless" growth pattern. According to clinical pathological features and immunohistochemistry, it is different from other soft tissue tumors. Long-term clinical follow-up is necessary for this kind of tumor.</p>

The amount of gastrointestinal associated lymphoid tissue (GALT) of 99 cases of autopsy died from various accidents has been examined by Videoplan. The results showed that the density of GALT in appendix (0.24mm~2/mm-length of GIT) is the maximum, the next is in ileum (0.0941/mm~2/mm). Since the total area of ileum is much more larger than that of appendix, it is suggested that ileum may possess the primarily important immunefunction in GIT.No statistical difference of aging associated changes of the amount of GALT could be identified in this study, however, a tendency of decline existed. The factors related with this result were discussed.
