The patient's history included a left testicular mesothelioma diagnosed 12 years earlier at orchiectomy and multiple surgeries for the same tumor, including a lymph node metastasis in the right inguinal region at the site of the current lesions.On physical examination, two shiny nodules were found at the margins of a surgical scar on the patient's right thigh (Figure 1). The lesions were excised under local anesthesia and examined histologically. Representative areas are shown in Figures 2 through 4.What is your diagnosis?
