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.
