Abstract
Ultrasound or CT-guided fine needle aspiration was performed on 212 patients with space occupying lesions of the liver during a period of 5 years (1986-1990) to study the utility of fine needle aspiration (FNAC) in the diagnosis of hepatic malignancies. The initial FNAC diagnosis was malignancy in 91 cases. However, following review of the smears by one of the investigators (DKD) 93 (43.9%) cases were found to be malignant. Age of the patients with malignancy ranged from 20 days to 85 years. Male to female ratio was 57:36. The clinical diagnosis was malignancy in 58% which improved to 72% following imaging whereas nonspecific diagnosis was reduced from 34% to 20%. The primary malignancies consisted of 21 cases of hepatocellular carcinoma (HCC) and 7 hepatoblastomas. There were 61 metastatic lesions which included 43 adenocarcinomas, 6 small cell anaplastic carcinomas, 3 leiomyosarcomas, 2 cases each of malignant melanoma, paraganglioma and germ cell tumour, and one case each of squamous cell carcinoma, neuroendocrine tumour and undifferentiated carcinoma/soft tissue sarcoma. In two cases decision between HCC and secondaries was not possible. There were also two cases of non-Hodgkin's lymphoma. Thirty six percent of primary malignancies and 58% of secondaries were correctly diagnosed or suggested as one of the possibilities by combined clinical examination and imaging prior to FNAC. Thus, US/ CT guided FNAC played an important role in diagnosis and classification of malignancies of liver.
