There is a big difference between perianal folliculitis and perianal abscess, and patients are advised to differentiate them from the nature and symptoms. 1. Nature: perianal folliculitis is usually not pathologically related to the rectum and anus, and is usually a rice-like lump, and will be accompanied by surface whitening. Perianal abscess is usually a purulent infection of the tissues or interstitial space around the anus and rectum, and leads to abscess formation, which is usually a lump or bulge in the perianal area. 2. Symptoms: perianal folliculitis may have no obvious discomfort, a few patients may have symptoms of localized pain, most do not have a feeling of swelling, and will not affect defecation. Perianal abscess usually presents pus, pain, bleeding, swelling symptoms, and may be accompanied by fever, fatigue and other systemic inflammatory manifestations, if the situation is more serious, it should also be timely treatment through surgery. It is recommended that patients should go to the hospital for examination and treatment when the above symptoms occur, so as not to delay the condition.
