Figure 4 Lymphoepithelial cyst of the pancreas with sebaceous differentiation. A: The cyst was localized in the pancreatic tail. The arrow depicts the area with sebaceous differentiation (5 × magnification); B: The cyst was lined by stratified squamous epithelium. Note the dense lymphatic tissue with formation of germinal centers in the cyst wall (80 × magnification); C: Numerous mature sebaceous lobules were present within the stratified squamous epithelium (40 × magnification); D: In addition to mature sebaceous glands, focal formation of sebaceous ducts was also present (80 × magnification).
