Intraepithelial Atypical Lymphocytes in Oral Lesions of Behçet's Syndrome

Abstract
• Atypical lymphocytes with deep nuclear indentations, identical to those observed in Sézary syndrome and mycosis fungoides, were demonstrated by electron microscopy in the prickle-cell layer of the oral epithelium of patients with Behçet's syndrome. Many of these cells were present in association with macrophages. (Arch Dermatol 117:83-85, 1981)
