Muco-epidermoid tumours of the anal canal.
The pathology of 21 cases of muco-epidermoid carcinoma of the anal canal is described. These tumours are defined as squamous or transitional cell carcinomas containing areas which secrete mucin of undoubted epithelial origin within the clumps of tumour cells. They are found in that part of the anal canal just above the dentate line where the epithelium is variable in type and represents an embr...
متن کاملMR of fourth-ventricular epidermoid tumors.
Epidermoid tumors arising from the fourth ventricle are uncommon. Although they may grow to an enormous size in a very critical location, the majority of patients do not have the explosive symptoms and neurologic findings common to most fourth-ventricular tumors. We present one confirmed case and one highly suggestive case of epidermoid tumor of the fourth ventricle. Both were evaluated by MR i...

Intradural epidermoid tumors occur more often in patients with a history of one or more lumbar punctures (1-4). It is hypothesized that they result from skin fragments introduced into the thecal sac during lumbar puncture and that they differ from the congenital heterotopic lesions.

متن کاملVisibility of epidermoid tumors on steady-state free precession images.
PURPOSE To determine whether steady-state free precession sequences improve the MR visibility of epidermoid tumors in comparison with spin-echo images. METHODS Patients were four women and three men with epidermoid tumors in the subarachnoid spaces. MR was performed with a 1.5-T superconductive unit. For steady-state free precession imaging, three-dimensional Fourier transform fast imaging wi...
