Abstract

Telangiectatic hepatic adenoma (THA) is a benign neoplasm treated by resection. The role of liver needle biopsy in identifying THA before resection has not been evaluated. We identified 55 patients who have undergone resection for hepatic adenoma (HA), THA, or focal nodular hyperplasia (FNH) after needle biopsy. Needle biopsies and resections were evaluated for the following: (1) abortive portal tracts; (2) sinusoidal dilatation; (3) ductular reaction; (4) inflammation; (5) aberrant naked vessels; (6) nodules, fibrous septa, and/or central stellate scar. THA diagnosis was made if the lesion had the first 4 criteria and lacked criterion 6. Most patients (36 of 55), including patients with THA (12 of 16), had multiple lesions (0.2 to 14.4 cm). Patients with THA showed no difference in age, body mass index, prevalence of diabetes or glucose intolerance, or presence of oral contraceptive (OCP) use from patients with HA or FNH, but patients with THA had longer periods of OCP use than patients with HA. Thirty-one percent of THAs had tumor hemorrhage. Of sampled THAs, 27% showed steatosis compared with 76% of sampled HAs (P<0.05). All resected HAs and FNHs were correctly diagnosed on needle biopsy. Of 14 patients with resected THA, 3 histologic patterns were noted on needle biopsy: (1) All THA criteria and naked vessels were present in 6 patients (43%). (2) Consistent with HA: naked vessels only were present in 4 patients (29%). (3) Suggestive of THA: some but not all THA criteria were present in 4 patients (29%). No needle biopsy of a THA was misdiagnosed as FNH. Although evaluation of resection specimens is the gold standard for diagnosis of THA, liver needle biopsy is a useful diagnostic tool that leads to adequate treatment.
