Testicular skin peeling, i.e., scrotal skin peeling, may be related to chronic eczema of the scrotum, scrotal lichen planus, riboflavin deficiency and other causes. 1. Chronic eczema of the scrotum: If eczema recurs, it can cause thickening and peeling of the skin at the scrotum. 2. Ringworm of the scrotum: Fungal infection of the scrotum area can manifest as scaly patches. 3. Riboflavin deficiency: due to the lack of riboflavin in the human body, sebum secretion can be increased, which reduces the metabolism of the skin, and the phenomenon of scrotal skin peeling may occur. It is recommended that the scrotum skin peeling people go to the hospital in time to clarify the cause of the disease, under the guidance of the doctor for standardized treatment, so as not to delay the condition of the body to bring adverse effects.
