A variant of port-wine stain characterized by a pale red or even pink tone, in contrast to the darker hue of the port-wine stain. By analogy with the term port-wine stain, this variant rose-wine stain, or nevus roseus. Nevus roseus, however, cannot be definitely diagnosed until adulthood as port-wine stains are sometimes pink in children. While the natural history of port-wine stains includes hypertrophy, darkening, and nodularity, nevus roseus remains unchanged for life. [from
