Brown spots on Marys skin The ABCD witness is: * A is for ASYMMETRY: half of a mole or birthmark does not discipline the other. * B is for BORDER: The edges are irregular, ragged, notched, or blurred. * C is for affectation The people of colour is not the said(prenominal) all over, but whitethorn have differing shades of brownness or black, sometimes with patches of red, white, or blue. * D is for DIAMETER: The region is larger than 6 millimeters ( or so ¼ in -- the sizing of a pencil eraser) or is growing larger. Superficial scatter melanoma can, in umpteen cases, be recognized as an extension of the ab chemical formulaities noted in dysplastic nevi. Its features include Asymmetry, boring of Border, Color variation, and large Diameter. These ABCD rules can be effectual, but some(prenominal) melanomas are not identified using them. For instance, the D of ABCD includes a lesion diameter greater than 6 mm in diameter. gestate to an educated physician and general public, melanomas in Australia are diagnosed comminuted than 6 mm 60 percent of the time. Thus size alone is not a useful predictor, unless the lesion is large. Similarly, edge and simulation variation are common in very comminuted bracing nevi that are not dysplastic. As nevi evolve beyond 2 to 4 mm, the variation becomes less and less in the normal nevus.

Conversely, the irregularity of edge and color can be accentuated in the dysplastic nevus evolving into a melanoma. Thus, while the ABCD rule is useful as a way of thinking about morphology, stark adherence to it may result in the wanting(p) of some melanomas. fo unt # 2 [Fractured Tibia of Johnny] Long Bo! ne has a overweening vascular supply.
