This chapter focuses on variant types of pancreatic cancer, presenting 14 distinct cases, including colloid carcinoma, adenosquamous carcinoma, pure squamous cell carcinoma, hepatoid adenocarcinoma, medullary carcinoma, signet-ring cell carcinoma, and other subtypes (e.g., undifferentiated carcinoma with osteoclast-like giant cells). For each case, it details patient demographics, clinical manifestations, laboratory results, imaging findings (via CT/MRI), pathological examinations (gross, microscopic, immunohistochemistry), and definitive diagnoses. The discussions emphasize differential diagnosis from similar pancreatic lesions, key pathological and imaging features of each variant, and the value of multi-modality imaging combined with histopathology in accurate diagnosis, providing comprehensive clinical references for managing these rare pancreatic cancer subtypes.

摘要

This chapter focuses on variant types of pancreatic cancer, presenting 14 distinct cases, including colloid carcinoma, adenosquamous carcinoma, pure squamous cell carcinoma, hepatoid adenocarcinoma, medullary carcinoma, signet-ring cell carcinoma, and other subtypes (e.g., undifferentiated carcinoma with osteoclast-like giant cells). For each case, it details patient demographics, clinical manifestations, laboratory results, imaging findings (via CT/MRI), pathological examinations (gross, microscopic, immunohistochemistry), and definitive diagnoses. The discussions emphasize differential diagnosis from similar pancreatic lesions, key pathological and imaging features of each variant, and the value of multi-modality imaging combined with histopathology in accurate diagnosis, providing comprehensive clinical references for managing these rare pancreatic cancer subtypes.
