The clinicopathologic features of 21 @entity4236 are reviewed with emphasis on variables of potential diagnostic or prognostic value. The @entity1 ranged in age from 9 to 66 years (median: 49 years); 57% were @entity1 . At the time of diagnosis, one @entity5 was Kadish stage A, 11 were stage B, and nine were stage C. Nineteen @entity1 had extensive surgical resections, but in six instances these were considered incomplete. Six @entity1 (29%) developed @entity13177 and eight (38%) had @entity3 . Ten @entity1 (48%) were alive and free of disease from 10 to 239 months (median: 58 months) after diagnosis. Seven (33%) died of @entity5 , with a duration of survival ranging from 1 to 142 months (median: 27 months). A fibrillary intercytoplasmic back-ground was the most useful diagnostic feature microscopically and was present, at least focally, in 18 of 21 @entity5 . A @entity575 stain for neuronal processes was helpful when fibrils could not be seen on @entity1710 - and eosin-stained sections. Homer-Wright rosettes, when present, also aided in diagnosis but were well formed in only six @entity5 . The only clinical feature that correlated with prognosis was whether the @entity5 had been completely excised at initial presentation. Tumor @entity39 was the only histologic feature correlating with prognosis, but neither association was statistically significant. @entity3 , clinical stage, mitotic rate, and nuclear pleomorphism showed no relationship to survival in this series.

XXXX . A clinicopathologic study of 21 cases.
