The cause of coffee spot is unknown, generally no treatment is needed, but if it affects the appearance, it can be eliminated through family care, treatment of primary disease, physical therapy, etc., but there is a possibility of recurrence. 1. Family care: pay attention to maintain hygiene, strengthen skin cleanliness, avoid excessive friction and scratching, and apply moisturizing cream on the lesion area for protection. 2. Treatment of primary disease: coffee spot may be the clinical manifestation of Fanconi anemia, ataxia capillary syndrome, Albright syndrome, neurofibromatosis, leopard spot syndrome, mottled disease, etc. Active treatment of these primary diseases can improve the symptoms of coffee spot at the same time. 3. Physical therapy: grinding, freezing and other traditional treatments can be used, but these methods will cause some damage to normal skin while destroying the lesions, so Q laser, intense pulsed light, dermatological ultra picosecond and other laser treatments can also be used, but there is also the possibility of hyperplastic scar, atrophic scar, hyperpigmentation and other adverse reactions. Since coffee spots are easy to recur, no way can guarantee 100% cure, but physical therapy is basically the most effective treatment at present. It is suggested that coffee spot patients should go to the dermatology department of regular hospitals for consultation and treatment, and should not blindly use medication for treatment.
