DNA copy number alterations in pleomorphic leiomyosarcoma: A case report

Pleomorphic leiomyosarcoma (P-LMS) is a rare morphological variant of LMS. The current study presents the cytogenetic data of a P-LMS that arose in the axillary region of a 31-year-old male. The results of array-based comparative genomic hybridization for the primary tumor showed DNA copy number alt...

Sumario:Pleomorphic leiomyosarcoma (P-LMS) is a rare morphological variant of LMS. The current study presents the cytogenetic data of a P-LMS that arose in the axillary region of a 31-year-old male. The results of array-based comparative genomic hybridization for the primary tumor showed DNA copy number alteration (DCNA) gains of 8ptel, 17ptel and 17q11.2 and losses of 2ptel, 7ptel, 7qtel, 10p15, 12p12-13.1, 13q14.2-14.3, 15q25-26 and Yq11. However, a metastatic lesion showed cytogenetic data different from the primary tumor DCNAs, with only the locus of 17ptel (282M15/SP6) in common between them. These observations add to the spectrum of DCNAs that have been reported in previous cases of LMS and provide novel cytogenetic data.
