αEβ7 Expression Increases With the Extent of Cutaneous Involvement in Mycosis Fungoides.

Background: Cell adhesion molecules are essential to lymphocyte migration in neoplastic and inflammatory skin diseases. Our aim was to investigate possible differences in cell adhesion molecule expression between mycosis fungoides (MF) and inflammatory skin diseases (drug reactions and allergic contact dermatitis).

Methods: We selected 33 biopsies from patients with MF and 10 biopsies of patients with inflammatory skin diseases from Department of Pathology-Universidade Federal de São Paulo (UNIFESP) from January 1997 to December 2013.
