2 Developmental and Congenital Conditions

Diffuse White Lesions

Diffuse white developmental conditions are often dyskeratotic lesions and represent oral manifestations of genodermatoses. Oral lesions seen in dyskeratosis congenita are usually oral dysplasias/leukoplakias; oral lesions of pachyonychia congenita are rarely biopsied. Oral lesions of hereditary mucoepithelial dysplasia, a condition of defective expression of cytoskeleton-junctional elements, presents as erythematous mucosa.
