摘　　要：BACKGROUND Perirectal epidermoid cysts are rare masses arising from the ectodermal germ cell layer of the hindgut and are predominantly found in middle-aged women.It is often difficult to make an accurate diagnosis of these cysts and it is equally challenging to distinguish it from other developmental cysts.CASE SUMMARY We report the case of an 18-year-old female patient with a perirectal mass who presented to the hospital with constipation.The patient experienced sacrococcygeal falls and burns on the left buttocks during growth.Three-dimensional computed tomography scans indicated abnormal sacral vertebrae with the sacral canal partially enlarged and opened.Pelvic magnetic resonance imaging showed a 55 mm × 40 mm × 35 mm unilocular cystic mass in the perirectal space and a solitary sinus in the left ischiorectal fossa.The cyst was completely resected posteriorly using the sacrococcygeal approach.The pathology was verified to be an epidermoid cyst.The patient remained recurrence-free after 6 mo of follow-up.CONCLUSION Successful treatment of perirectal epidermoid cysts depends on comprehensive evaluation.This is significant for the surgical approach and prognosis.
