Solid variant of alveolar rhabdomyosarcoma with unbalanced t(2;13) and hypotetraploidy, without MYCN amplification

Pathology. 2001 Feb;33(1):108-11.

Abstract

The histological subtype of alveolar rhabdomyosarcoma (AR) is characterised by the cytogenetic translocation t(2;13)(q35;q14) in approximately 70% of cases, a rearrangement rarely present in the embryonal rhabdomyosarcoma (ER) subtype. The MYCN gene is amplified in some cases of AR. We present a young man with an unusual pattern, namely solid variant of AR with hypotetraploidy and the t(2;13) in an unbalanced form. The MYCN gene was not amplified on FISH, but showed increased copy number, consistent with ploidy.
