Freckle-like nevi usually occur at a young age.
A freckle-like nevus is a brown or black spot on the skin or mucous membranes. The etiology is not known and there is no clear genetic factor. Freckle-like nevi can occur anywhere on the body, as well as at the junction of the skin and mucous membranes or in the conjunctiva of the eyes. The common symptoms of freckle-like nevus are brown or dark brown spots of uniform colour, rice to pea size, with clear borders and a smooth surface, disseminated, solitary or multiple, but not fused, and may be confined to one area or generalised. The colour does not deepen after sun exposure and does not disappear in winter. The rash persists and does not fade on its own. It is uncomfortable and usually does not require treatment.
If necessary, laser, excision or iontophoresis treatments are available. Laser treatment for freckle-like nevus is still very effective, but treatment should be accompanied by sun protection, avoiding humidity, keeping a happy mood, avoiding anxiety and worry, and adopting good habits of rest and relaxation to avoid staying up late to facilitate healing.
