“…In pleomorphic adenomas, the luminal surface of tubular, ductal, duct-like, and cystic structures was positive for IVL, whereas myoepithelial cells surrounding the duct-like structure were found to be immunonegative for IVL staining. They observed the potential of IVL as a specific marker for detecting squamous metaplasia or keratinizing change in the epithelia of salivary gland tumors (Sumitomo et al 1986).…”
