[A case of umbilical endometriosis following cesarean section].

Umbilical endometriosis is a rare pathology whose etiopathogenesis is still uncertain and the theories put forward are all controversial. Diagnosis is therefore frequently difficult. The authors report a case of umbilical endometriosis which occurred in a scar left by an earlier cesarean section. Moreover, they discuss the aspects which might facilitate the diagnostic approach and a correct therapeutic management.
