RESUMO
Focal nodular hyperplasia (FNH) is a benig nepithelial tumor of the liver. The etiology of FNH is unknown, but recent evidence suggests that FNH may represent a localized, hyperplastic response to a pre-existing vascular malformat ion. There is a high probability of as sociat edlesions , most commonly hepatic hemangiomas, meningioma, as trocytoma, and arterial dysplasia in various organs . In the present report we describe a FNH with aberrant lymphatics in a 24-year-old woman. In operation field, lymphatics were located on the site of falciform ligament. Histologically, aberrant lymphatics were composed of well vas cularized complex lymphatic channels and the mass were typical FNH. In this case, the role of aberrant lymphatics in the development of FNH was unclear . But as the FNH frequently as sociated with ot her anomalies , we think the aberrant lymphatic as such anomaly that have not been reported.
