Salmon patches - DiagnosisNevus simplex are easy to diagnose by visual observation. Salmon patches are pink in color and appear flat. They are irregularly shaped and may appear as small lesions or may cover a great area. During the flushing of the face due to change in temperature or crying of the baby these marks turn dark red. When pressure is applied on them, these birthmarks fade and appear pale.
Differential diagnosis of salmon patchesNevus simplex can be differentiated from birthmarks like hemangiomas and port-wine stains. Skin hemangiomas have a rapid growth phase followed by an involution phase. They appear as raised swellings. Port-wine stains, may initially may have similar appearance, but do not fade and persist. Over time, port-wine stains become dark red or purple in color, thicken, become uneven and show hypertrophy (increased tissue mass). Nevus simplex are flat and do not grow.
Treatment of salmon patchesThese birthmarks are temporary and in most of the cases they fade and disappear by two years. Normally nevus simplex do not require treatment as they disappear with the growth of the baby. If these birthmarks persist beyond three years, usually in the back of neck, they can be removed by cosmetic laser procedure to improve the aesthetic appearance of the baby. There is no known preventive treatment for these birthmarks.
Most of these birthmarks fade and disappear in two years. Nevus simplex on the nape of the neck may not resolve and may persist. However salmon patches must be examined by pediatrician to rule out any complications or disorders.
