[McKusick-Kaufman syndrome: diagnostic and therapeutic problems].

Mc Kusick-Kaufman Syndrome (SMK) is an autosomal recessive multiple malformation Syndrome characterized by hydrometrocolpos and polydactyly. This Syndrome is more frequent in females, whose parents are first-degree cousins (frequency 1:8 liveborn). We describe two cases of SMK: a male and a female. Patients were siblings and their parents were first cousins. The first child presented postaxial hexadactily, of the hands and feet, cardiovascular malformation and Arnold-Chiari II malformation. The baby died on the 17th day of life, for neurosurgical complications. Second baby, in which a prenatal ultrasonography showed a large cystic dilatation in the pelvis, presented with urinary hydrometrocolpos associated with persistent urogenital sinus (UGS) and polydactyly. The patient was temporary treated with intermittent vaginal catheterization. At age of 6 months she underwent reconstructive surgery via the anterior sagittal transanorectal approach (ASTRA), previous creation of a colostomy. Thirty-two months of the operation, the patient is continent for stool and urine and the vagina looks normal.
