Clark level is reported by roman numerals (i.e. I to V) with V being the deepest level of invasion.A level I melanoma is confined to the lower boundary of the epidermis and more commonly called melanoma in situ. Level II-IV melanomas describe different degrees of penetration or invasion into the dermis and fat layers below the skin. A level V melanoma has penetrated the subcutis, the fat layer beneath the skin.
