Surgery was performed 24 hours after a smooth C-section delivery. The birth weight was 3630 grams, Apgar 10/10. The tumor was 90% cystic (250 cc) and a solid component was attached to the precoccigeal area (nut size). Excision was 100% complete with the coccis. The tumor base was asymmetric to the left of the midline raphe. Levator ani and sphincters were realigned and repaired adequately . The cosmetic result is acceptable after skin flaps were raised to corrected the dysplaced intergluteal line. 

The baby has successfully initiated breast feeding without complications, at her first postop day in normal conditions.
