[Presacral tumor as a differential diagnosis of recurrent pilonidal sinus].

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.
