RESUMO
Hepatic small vessel neoplasm (HSVN) is a recently described vascular neoplasm of the liver. It demonstrates an infiltrative growth pattern and lacks cytologic atypia and mitotic activity. So far, no cases of metastasis or disease recurrence after excision have been reported in the literature. In this report, we present the case of a 31-year-old woman with a lesion in segments VII-VIII of the liver who was referred to our surgical department due to right lumbar pain. She underwent an atypical wedge hepatectomy (segments VII, VIII) and cholecystectomy. The histopathology of the resected specimen confirmed a 40mm HSVN. The patient did not receive any adjuvant therapy and is scheduled for follow-up with serial magnetic resonance imaging (MRI) scans over the next five years due to the unknown malignant potential of the tumor.
