ABSTRACT
Hepatocellular carcinoma (HCC) metastasizes to the brain is rare instances. In published series and case reports of metastatic HCC, diagnosis of central nervous system metastases has been determined by histologic methods. We present a case of metastatic HCC of brain diagnosed by squash cytologic preparation. A 69-year-old male, HCV positive, suffering from post-hepatitic cirrhosis, initially diagnosed at age 68 with HCC presented with headaches of increasing frequency and severity. A computed tomography scan confirmed a 3-cm nodule in the right parietal lobe of the brain. Squash cytology was performed intraoperatively and preparations of a small tissue fragment resected from the mass showed medium-to-large-sized, well-cohesive clusters or sheets of uniform tumor cells. The tumor cells are highly cellular and contain solitary tumor cells in loose groupings as well as many fragments. They also appear somewhat bizarre and contain large, round, or ovoid nuclei with prominent nucleoli. Cytologic diagnosis of metastatic HCC was rendered reported and confirmed by a subsequent frozen section examination. To the best of our knowledge, this is the first reported case in which HCC was reported as brain metastasis, by using squash cytology. We suggest that intraoperative squash cytologic examination be viewed as a useful initial approach in the diagnosis of metastatic brain tumor.
