BACKGROUND This 26-year-old man has mixed germ cell tumor (testicular cancer) with metastasis to the lungs. One year prior to his admission, stage I testicular cancer was diagnosed. The patient underwent right orchiectomy. Pathology revealed mixed germ cell tumor. After surgery his levels of the tumor marker alpha-fetoprotein were normal. The cancer was in remission, but then follow-up CT scans showed multiple lung adenopathies and pulmonary nodules. His alpha-fetoprotein levels also became elevated. The patient denies having a history of coronary artery disease and is not taking any medications. He denies alcohol or drug abuse. He has smoked half a pack of cigarettes per day for 9 years. He had no significant adverse effects after his first dose of chemotherapy with cisplatin, bleomycin, and etoposide. On day 8, he received another dose of bleomycin without any adverse event; however, he presented to the emergency department 36 hours later because of severe, crushing chest pain accompanied by shortness of breath and diaphoresis. Figure 1 shows his ECG, and Figure 2 shows an image obtained during cardiac catheterization. Hint Focus on the patient's medications and chest pain. Author: Jane T. Tan, RN, and Winston W.
