Malignant PCCs can only be diagnosed with certainty if metastases are present. Here we describe adrenal tumours generated in a\n                    <jats:italic>Pten<\/jats:italic>\n                    conditional knock\u2010out (KO) mouse model. We characterized the molecular alterations in these tumours and compared them with human PCC. Thirty\u2010two of 41 (78%) male\n                    <jats:italic>Psa\u2010Cre;Pten\u2010loxP\/loxP<\/jats:italic>\n                    mice presented adrenal tumours that were shown to be PCC by histology and by immunohistochemical staining for enzymes in the catecholamine biosynthetic pathway. In 6 of 17 investigated mice, histological and immunohistochemical evidence was obtained for the presence of PCC lung metastases. Array comparative genomic hybridization (CGH) analysis of the primary tumours showed loss of chromosomes 6 and 19, which are syntenic to human 3p and 11q. Another frequent alteration found was gain of chromosome 15, which is syntenic to human chromosome 5. The molecular aberrations in the mouse model corresponded to the alterations found in a subtype of human PCC, suggesting that the PCC of the\n                    <jats:italic>Pten<\/jats:italic>\n                    KO mice might be representative of human PCC. The mouse model should allow further studies into the pathogenesis of human malignant PCCs and into therapeutic strategies for these tumours.
