Carcinosarcoma of the prostate: Report of a case with unusual histological findings
Abstract:Lindboe CF, Klem KH. Carcinosarcoma of the prostate. Report of a case with unusual histological findings. APMIS 2006;114:153–8.
We report the case of a 66-year-old man who was diagnosed as having prostatic adenocarcinoma with widespread skeletal metastases. After treatment with a luteinizing hormone-releasing hormone analog for one year, a second biopsy revealed transformation of the tumour into a carcinosarcoma with heterogeneous and unusual findings in the carcinomatous as well as the sarcomatous component. Among others, these included a papillary growth pattern and a liposarcomatous differentiation. The patient died 5 months after the diagnosis of carcinosarcoma.
