Pilonidal disease is diagnosed on the basis of the history and physical examination. The typical location of the midline pits superior to the anus and overlying the sacrum and coccyx is a hallmark of the disease. [10] Occasionally, pilonidal disease can track from a fistula around the anal canal and consequently be confused with anal fistula; however, this is rare. During physical examination, broken hairs can often be extracted from the pilonidal sinus.
