ABSTRACT
INTRODUCTION AND IMPORTANCE: Primary squamous cell carcinoma (PSCC) of liver is quite rare and very few cases reported in literature. It has high metastatic rate with poor prognosis. The pathogenesis is unclear, but is generally considered to be correlated with the long-term inflammation or metaplasia of biliary epithelial cells or congenital cyst of the liver. We report here a case of PSCC of liver which mimicked a complex hydatid cyst. CASE PRESENTATION: A 25 years male admitted with right hypochondrium pain associated with fever and yellowish discoloration of eyes for 20 days. He was jaundiced with epigastric tenderness and deranged liver function tests. When thoroughly investigated with ultrasound, CT abdomen and MRI liver, he was found to have a large cystic lesion in right lobe of the liver. He underwent right hepatectomy, peri-cystectomy of the cyst and T-tube placement in common bile duct. Histopathology of the resected sample showed primary squamous cell carcinoma of liver. Patient was discharged after 7 days and died after 6 months due to acute liver failure. CLINICAL DISCUSSION: Because of a very low incidence of hepatic SCC, there is not a single definite therapeutic regime and various different methods of management include surgical resection, generalized chemotherapy, radiotherapy, Hepatic Arterial ChemoEmbolization (HACE) and the combinations of these therapies. CONCLUSION: PSCC is a rare condition of the liver and is associated with other benign liver conditions such as non-parasitic and epidermoid cysts. Histopathology with radiological investigations are needed to diagnose and treat this aggressive tumor before it metastasizes.
