A case of primary squamous cell carcinoma of the gallbladder with local invasion of the liver and peritoneum, and metastasis to the omentum

Abstract

Primary squamous cell carcinoma of the gallbladder is a rare entity that comprises approximately 1%-3% of all primary gallbladder cancers. We report the case of a 37-year-old woman who was diagnosed with a locally invasive squamous cell carcinoma of the gallbladder. Surgical pathology revealed a predominantly squamous cell carcinoma composition of the tumor with a few microscopic foci of adenocarcinoma (<1% of tumor). We discuss pertinent clinical features, risk factors, and imaging characteristics to prompt early diagnosis and treatment, which will ultimately lead to improved patient outcomes.
