The hypopigmented spots are not necessarily vitiligo, but can also be sweat spots or seborrheic dermatitis, or idiopathic punctate white spots, which can be identified clinically by applying skin CT or dermoscopy or Wood’s lamp. The white spots of vitiligo are usually porcelain white with clear boundaries around them, brown pigmentation marks can be seen and white hairs can be seen within the white spots. Sweat spots are mainly caused by fungal infections and can be treated clinically by applying terbinafine hydrochloride ointment. While idiopathic punctate leukoplakia, mainly due to the appearance of soy-sized white spots as the body ages, seborrheic dermatitis can be seen as fine white scales on the surface of the white spots.
