External hemorrhoids are hypertrophic skin tags at the anal margin and surrounding skin, or dilation of the subcutaneous venous plexus leading to blood stasis and thrombus formation, resulting in protruding lesions. According to their characteristics, they can be divided into connective tissue external hemorrhoids, thrombotic external hemorrhoids, varicose external hemorrhoids, and inflammatory external hemorrhoids. In particular, inflammatory external hemorrhoids can cause the surrounding skin to become moist. This moisture can lead to the formation of eczema and pruritic diseases in the surrounding skin, causing skin lesions. One of the main features after skin lesions is itching around the skin surrounding the external hemorrhoids.
