Immunohistochemical aspects of E-cadherin membrane antigen stain; original magnification, 40×.(A) Pleomorphic adenoma in human salivary gland with membrane E-cadherin stain; (B) Mixed tumour in canine mammary gland with membrane E-cadherin stain; (C) Carcinoma ex-pleomorphic adenoma in human salivary gland with evident loss of membrane E-cadherin marker; (D) Metaplastic carcinoma in canine mammary gland with evident loss of E-cadherin membrane marker. Note the loss of expression in malignant tumours.
