A pilonidal cyst is known to be a recurrent infectious disease in the sacrococcygeal region and it usually affects adolescents and adults. It is often misdiagnosed as a simple abscess or a sebaceous cyst, so there are many patients with pilonidal cysts who have gone through several operations. Although many treatments for this malady have been reported, the principle treatment for pilonidal cysts is radical excision. We report here on two cases of pilonidal cyst and the patients were misdiagnosed as having a simple abscess. We planned to perform incision and drainage, but the lesions were finally diagnosed as pilonidal cysts and so we performed radical excision for the treatment. We also review the medical literature on abscesses that occur in the sacrococcygeal region in early adulthood.
