Recurring reciprocal translocations have been identified as the primary chr
omosome aberrations in a number of neoplasms. These aberrations are often c
losely associated with particular morphologic or phenotypic subtypes of tum
ors and in some cases have prognostic implications. We have identified a no
vel reciprocal t(10;17)(p11.2;q23) in a case of law-grade myxoid fibrosarco
ma, which may prove to be a new tumor specific chromosome aberration. (C) 2
