Salmon patches, except those located in the occiput and nape, tend to disappear or significantly regress with time.
Salmon patches tend to fade and disappear with time; nuchal lesions tend to persist longer [3, 10, 11].
Aghaei evaluated the efficacy of diphenylcyclopropenone in the treatment of severe alopecia areata, observing that salmon patch was present in 40.7% of the patients, whereas nail involvement (already known to be associated with a worse prognosis) was seen in 59.3% and thyroid diseases in 11.1%.
demonstrated a significant increase in the incidence of salmon patch in patients with more severe forms of alopecia areata--such as ophiasis, totalis, and universalis--compared to the general population, suggesting that the presence of the lesion could be a useful marker of widespread and chronic disease.
Although salmon patch is a benign condition that does not require treatment, it should be differentiated from other lesions that may require therapeutic intervention, such as port wine stains and infant hemangiomas.
