The difference between pathological and physiological coffee spots is mainly reflected in the cause, appearance and treatment.
1. Etiology: physiological coffee spot is caused by hypermelanosis and local pigmentation, while pathological coffee spot is a manifestation of skin diseases, such as neurofibroma.
2. Appearance: physiological coffee spots are small in size and quantity, and their shape and size will not change significantly with the passage of time. Pathological coffee spots are larger in diameter, usually more than 1.5cm, usually more than six in number, with different color shades and irregular shape.
3. Treatment: Physiological coffee spots generally do not cause damage to the patient’s health, and generally do not need special treatment. Pathological coffee spots need to be surgically removed, and further treatment plan will be clarified according to the results after pathological examination.
It should be noted that, in order to detect pathological coffee spots in time, it is recommended to do regular medical checkups and carry out regular treatment as soon as possible after discovery.
