[Caudal regression syndrome: about a case].

Caudal regression syndrome is a rare malformative syndrome associated, to varying degrees, with agenesis of sacral and coccygeal vertebrae, lower limb shortening and gastrointestinal, genitourinary and cardiovascular abnormalities. Its relationship with gestational diabetes is well established, but its exact cause is poorly established. We here report a rare case of caudal regression syndrome in a 8-month old infant of diabetic mother with polymalformative syndrome and chronic constipation.

[Vascular calcification in pseudoxanthoma elasticum in children].
