Metastatic Hepatocellular Carcinoma Presenting as Maxillary Sinus Lesion

Abstract

Metastasis of malignant tumors to the sinonasal area is an infrequent occurrence and usually indicates the late stage of the primary disease. We report a rare case of previously undiagnosed metastatic hepatocellular carcinoma presenting solely as a maxillary sinus lesion. We have also reviewed literature on hepatocellular carcinoma metastasizing to the sinonasal area and discussed the pathogenesis of the possible routes of metastatic spread.
