Multiple liver masses in a patient with breast cancer, metastasis or not? An unexpected diagnosis: hepatic fascioliasis. A case report and overview of the literature from Turkey.

A patient who underwent mastectomy of the left breast owing to breast cancer was referred to our department for abdominal ultrasonography during her routine check-up. Radiological examinations demonstrated multiple masses that tended to form clusters in the liver parenchyma, and the lesions were initially thought to represent metastases from the breast cancer. Multisite biopsies and serological tests confirmed the diagnosis of Fasciola hepatica infestation. To our knowledge, this is a unique case report of a patient with a known malignant neoplasm. We also present an overview of the literature about human fascioliasis in Turkey.
