This is a surgical pathology case of a 70-year-old woman with multiple bilateral relatively stable lung nodules and history of metastatic leiomyosarcoma of Mullerian origin status post debulking 4 years ago. During frozen section the rectosigmoid resection and the liver biopsy showed involvement by leimyosarcoma. However, the lesion found on a lung wedge resection could only be described as a biphasic tumor. On permanet section this lesion’s findings are shown below.
