Metastatic choriocarcinoma of the lung without a primary: A case report

Abstract

Delayed presentation of metastatic gestational choriocarcinoma is a very rare phenomenon. We report a case of a 43-year-old female who presented three years after giving birth with a right lung mass and elevated β-human chorionic gonadotropin (HCG) levels. She underwent a right thoracotomy with right lower lobe lobectomy. The final pathology revealed metastatic gestational choriocarcinoma. In these cases, resection is recommended and patients often benefit from adjuvant chemotherapy. The patient was successfully treated with resection and is currently undergoing chemotherapy treatment. A delayed presentation of metastatic gestational choriocarcinoma should be considered as a differential in women presenting with a lung mass and a history of previous pregnancy. Prompt diagnosis and treatment can improve patient outcomes.
