Projection resembling a supernumerary digit with a collar at its base (the supernumerary digit is distinguished by the presence of nerve fibers).
Dense collagen fibers parallel to the axis of the lesion, therefore perpendicular to the epidermal surface
Multiple vessels
Massive hyperkeratosis of the orthokeratotic type
