Background:
Retrorectal or presacral space is occupied during embryological stem cell development and therefore may contain a heterogeneous group of tumors.
Clinical Case:
We report the case of a 22-year-old male with a pilonidal cyst operated due to recurrent pilonidal sinus cyst. Final diagnosis after pelvic computed tomography is large retrorectal cystic tumor and magnetic resonance diagnosis of a presacral cystic compatible wtih germ cell tumor. The tumor was removed surgically through the abdomen and diagnosis of cystic teratoma was established.
Conclusion:
Retrorectal tumors are rare lesions whose presence must be ruled out in case of recurrent sinus.
