Chemotherapy-induced response of liver hemangiomas in a patient with a germ cell tumor: a case report

Abstract

Liver hemangiomas are the most common benign primary tumors of the liver. Due to their high prevalence, incidental finding of hemangiomas during radiological workup of oncologic patients is not uncommon. We present the case of a patient diagnosed of an ovarian immature teratoma and hepatic lesions with typical radiological appearance of hemangiomas that decreased in size during adjuvant chemotherapy with BEP regimen (cisplatin, etoposide and bleomycin). Chemotherapy-induced shrinkage of hepatic hemangiomas can mimic the response of liver metastases to chemotherapy and may induce erroneous interpretations. The purpose of this report is to describe a chemotherapy-induced response of liver hemangiomas, especially when BEP combination is used. To date this observation has been barely reported in the literature and, to our knowledge, this is the first documented case of chemotherapy-induced response of liver hemangiomas in a patient diagnosed of an ovarian immature teratoma.
