Usually, the patient is afebrile and nontoxic. Local examination may show a relatively unremarkable sinus tract in the sacrococcygeal region, but, usually at ED presentation, the patient has typical findings of an abscess, including redness, warmth, local tenderness, and fluctuance with or without induration. A tender mass with sinus drainage may be present. [5] Loose hair may be seen projecting from the site. [8, 4]
