Due to the length of time these lesions been present, this could be a type of chronic dermatitis. Are there other signs or symptoms present? Contact dermatitis can be due to irritants, such as excessive bathing, soaps and tight socks, or to a specific allergic reaction. If the cause is uncertain, a dermatologist may be able to identify the specific allergens by patch testing. Other conditions such as conditions related to thyroid diseases, psoriasis, dry skin or vasculitis needs to be ruled out. It would be best to have this evaluated by your doctor. Management depends on identifying the particular pattern of dermatitis or other skin condition. Keep the area clean and dry. Try to avoid scratching to prevent secondary infection.
Take care and regards.
