Urothelial Carcinoma With Pulmonary Tumor Thrombotic Microangiopathy After Chemotherapy for Hodgkin Lymphoma
Abstract
Treatment-related second malignancies (SMs) remain a major concern in long-term survivors of Hodgkin lymphoma (HL). In this report, the autopsy findings of a patient with HL, who was in complete remission after chemotherapy but expired of pulmonary tumor thrombotic microangiopathy (PTTM) caused by urothelial carcinoma of the renal pelvis (UCRP), were described. A 78-year-old Japanese man with a history of classical HL developed irreversible heart failure about 2.5 years after chemotherapy. The patient expired shortly after being admitted due to ineffective treatment for heart failure. However, the cause of death was not determined. The patients autopsy findings revealed UCRP in the left kidney, as well as infiltration around the inferior vena cava and lungs, but no HL recurrence. The primary causes of mortality were respiratory and heart failure due to PTTM. Therefore, it is essential to consider the risk of SMs and search for them in patients with HL after chemotherapy.
