A new cytogenetic finding in an epithelioid sarcoma, t(8;22)(q22;q11).
We report a new translocation t(8;22)(q22;q11) in a single case of epithelioid sarcoma. The band involved in chromosome 22 is the same found in 70-80% of the case of Ewing's sarcoma/peripheral neuroepithelioma (PNET) with cytogenetic characterization. The histologic characteristics of this tumor were typical for epithelioid sarcoma. Immunohistochemical stains were also entirely consistent with this diagnosis, including non-reactivity with P30/32MIC2, a specific marker for Ewing's sarcoma/primitive neuroepithelioma.
