✦ Synopsis

Short-term cultures from two histologically benign chemodectomas, one from the carotid body and one from the vagal nerve, were analyzed cytogenetically. The former had a small abnormal clone with the karyotype 46,XX,t(3; I9)(q2 I ;q I 3),t( 12; IS) (p I 3;q 12-I4), whereas the majority of the cells from the latter tumor displayed two related abnormal clones: 46,XY,i( I )(q lo)/ 46,idem,add(2)(q37). The findings add to the evidence that chemodectomas are heterogeneous neoplasms and suggest that the heterogeneity may possibly be associated with the site of origin.

We report the first cytogenetic investigation of a Dupuytren's subungual exostosis. The clonal abnormalities found suggest that at least some of these heterotopic ossifications could be neoplastic in nature, instead of being a purely reactive process or exuberant growth in response to trauma.

Cytogenetics provides important insights into the molecular pathogenesis of human cancers. Although extensive data exist on recurring cytogenetic abnormalities in hematologic cancers, data on individual solid tumor types remain limited. Previous studies of ovarian carcinoma indicated the presence of
