External hemorrhoids refer to hemorrhoids located below the dentate line, which are classified into four main types, each with distinct clinical manifestations. Connective tissue external hemorrhoids and varicose vein-type external hemorrhoids primarily present with a mild sensation of a foreign body in the anus. Inflammatory external hemorrhoids are characterized by redness, swelling, protrusion, burning, or itching of the anal skin or skin tags. Thrombosed external hemorrhoids often occur after intense exercise or straining during bowel movements, suddenly presenting as a round or oval lump under the skin at the edge of the anus. This lump contains a venous thrombus and is accompanied by anal pain.
