title: E-cadherin expression in canine cutaneous histiocytomas.
abstract: Canine cutaneous histiocytoma is a common skin tumour of Langerhans cell origin. Langerhans cells are members of the dendritic cell family of antigen-presenting cells and are located in the epidermis. They are unique among the dendritic cell lineage in that they express high levels of the adhesion molecule E-cadherin. The expression of E-cadherin by the neoplastic Langerhans cells in 37 dogs with cutaneous histiocytoma was studied by flow cytometry and immunohistochemistry. In all the cases, these cells expressed E-cadherin, whereas the infiltrating lymphocytes did not.
