Spleen – S100P immunostaining is seen in granulocytes.
Stomach, antrum - A strong S100P immunostaining is seen in the surface epithelial cells and neck cells of the stomach while staining is markedly less intense or absent in gastric glands.
Stomach, corpus - A strong S100P immunostaining is seen in the surface epithelial cells and neck cells of the stomach while staining is markedly less intense or absent in gastric glands.
Sublingual gland - A moderate S100P immunostaining can occur in salivary glands (not in all samples).
