Endogenous porphyrin fluorescence after topical application of 20% aminolevulinic acid formulation to a solid basal cell carcinoma. Twelve hours after
aminolevulinic acid application, there was strong fluorescence of the tumor-bearing areas, and weak-to-no fluorescence of the surrounding dermis. Also
visible is fluorescence in the overlying epidermis. (From Szeimies RM, Sassy T, Landthaler M: Penetration potency of topical applied & alphaaminolevulinic acid for photodynamic therapy of basal cell carcinoma. Photochem Photobiol 59:73, 1994.)
