Patients with fleshy bumps on the buttocks are most commonly associated with hemorrhoids, but they are not always caused by hemorrhoids; they can also be anal polyps, anal warts, perianal abscesses, enlarged perianal lymph nodes, and perianal sebaceous cysts. There are two types of fleshy bumps from hemorrhoids, one is a prolapsed internal hemorrhoid and the other is a thrombosed external hemorrhoid. The fleshy bumps of prolapsed internal hemorrhoids often manifest as hemorrhoids that prolapse during defecation and can be returned by themselves after defecation or require manual return, sometimes not back to the anus, often accompanied by pain and blood in the stool. Thrombosed external hemorrhoids are often accompanied by severe anal pain due to thrombosis and subcutaneous hematoma. If the above characteristics of hemorrhoids are not met, consider other conditions and no longer consider hemorrhoids, and it is advisable to go to the hospital as early as possible to get a clear diagnosis.
