A cytogenetic study of extraskeletal myxoid chondrosarcoma cells revealed a complex t(9;22;15)(q31;q12.2;q25) as a primary chromosome change. A reciprocal translocation involving identical breakpoints on chromosomes #9 and #22 in this tumor has been reported in the literature. We suggest that the breakpoints 9q31 and 22.q12.2 are associated with extraskeletal myxoid chondrosarcoma, a comparatively rare tumor of adulthood.
