Blue white veil
Blue-whitish veil is a blue and focal structureless zone with an overlying white “ground-glass” haze. It occurs in raised/palpable areas of a lesion (Braun et al., 2005). Histologically, it corresponds to heavily pigmented melanocytes and/or melanophages or melanin in the dermis (in melanocytic lesions), in combination with acanthosis and compact orthokeratosis (Massi et al., 2001b, 2001a). Blue-whitish veil is associated with melanoma, but can also be seen in Spitz/Reed nevi and in non-melanocytic lesions such as SK, BCC and pyogenic granuloma (Braun et al., 2005; Zaballos et al., 2009).
