Huge solitary necrotic nodule of the liver: a rare case report with review of literature.

Solitary necrotic nodule of the liver (SNNL) is an uncommon disease in clinical practice, and its pathogenesis is still unclear. Here, we report the case of a 35-year-old woman. After physical examination, the patient was found to have a liver neoplasm, and there were no other physical complaints. Abdominal contrast-enhanced computed tomography (CT) showed the presence of a hypodense lesion. The patient opted for surgery to eliminate the lesion. Pathologic examination revealed an isolated necrotic nodular lesion with a size of 12 cm×10 cm×10 cm. The patient had a history of hepatitis B infection. To our knowledge, this is the largest SNNL ever reported and the first case with a history of hepatitis B infection.
