case_images: The patient had been well 1 month before admission until a surveillance head computerized tomography (CT) performed at another hospital revealed a mass 1.4 cm by 1.1 cm in diameter in the right maxillary sinus ( Figure 1C ). The patient's prior history revealed that 9 years before admission in 2014 the patient presented to our hospital's hepatobiliary department with a mass found in the left liver lobe on CT of the abdomen, the mass measured 9 cm by 7.5 cm in diameter ( Figure 1B ).
case_images: Resected maxillary sinus specimen and pathological examinations. (A) Specimen of the resected right maxillary sinus mass. (B) 2014/04: Histopathological examination of the liver mass post-resection revealed moderately differentiated hepatocellular carcinoma cells (H&E). (C) 2023/05: Histologic section of the right maxillary sinus lesion revealing neoplastic cells arranged in a thick trabecular pattern, consistent with metastatic hepatocellular carcinoma (H&E stain).
