Transepidermal elimination of actinically damaged connective tissue.
Three patients with actinically damaged skin had scaling lesions clinically resembling actinic keratoses. Histologic examination of the lesions disclosed transepidermal elimination (TE) of degenerated (solar elastotic) dermal connective tissue via a transepidermal canal, a previously undescribed phenomenon.
