| Abstract: | Hepatic sarcomatoid carcinoma is a rare liver malignancy with atypical clinical symptoms and a high degree of malignancy. To improve the understanding of this disease, we collected the clinical and pathological data of 14 patients with hepatic sarcomatoid carcinoma admitted to the First Affiliated Hospital and Second Affiliated Hospital of Bengbu Medical College from 2011 to 2021 and reviewed the relevant literature.The clinical and pathological data of 14 patients with hepatic sarcomatoid carcinoma were collected from the electronic medical record system of the 2 hospitals. All clinical data were independently reviewed by 2 clinicians, and all pathological data were independently reviewed by 2 pathologists. At the same time, we reviewed the related literature on hepatic sarcomatoid carcinoma in Pubmed and CNKI.This group of 14 patients, 10 males and 4 females, aged 50–77 years. The main symptoms of the patients were abdominal pain, bloating, anorexia, fatigue or weight loss in the upper abdomen, and 3 patients were asymptomatic. On imaging, hepatic sarcomatoid carcinoma manifests as heterogeneous mass with irregular shape and unclear boundary, and computed tomography (CT)/magnetic resonance imaging (MRI) enhanced scan shows progressive or persistent heterogeneous enhancement, marginal enhancement or annular enhancement, and central necrosis. The pathological features of hepatic sarcomatoid carcinoma are the proliferation of spindle cells and pleomorphic cells, which alternate with acinar cells.Hepatic sarcomatoid carcinoma is more common in middle-aged and elderly patients, especially men, and has no characteristic clinical manifestations. Imaging examination and B-ultrasound-guided liver biopsy + immunohistochemistry can help diagnose. Radical surgery is the preferred method for hepatic sarcomatoid carcinoma, and postoperative adjuvant chemotherapy is expected to prolong patient survival. |
