Occurrence of two histopathologically different malignancies.

BACKGROUND Synchronous primary malignancies are defined as two or more malignancies without finding a subordinate relationship in different organs of the patient. Reports of patients with primary malignancies with hepatocellular carcinoma are rare. CASE We describe the course of the disease in a 71-year-old patient with a synchronous occurrence of two histopathologically different malignancies. CONCLUSION Consistent screening can detect individual tumors early. Understanding the clinicopathological properties and prognostic factors in synchronous malignancies is important to facilitate the treatment.
