Pierre Robin sequence coexisting with ectopic kidney, bilateral developmental hip dysplasia in a child - A rare case report.

Pierre Robin sequence is a rare congenital disorder with variable associations. A two-year-old female child was brought in with complaints of an abnormal gait and right lower limb shortening. A comprehensive clinical evaluation unveiled facial characteristics resembling those of Pierre Robin Sequence, including micrognathia, a cleft palate, and glossoptosis. The child also exhibited retrognathia, a low posterior hairline, bilateral developmental dysplasia of the hips, right foot syndactyly, and a left ectopic kidney as confirmed by ultrasonography. Radiological examination showed bilateral developmental dysplastic hips. The connection between Pierre Robin sequence and the presence of bilateral dysplastic hips and an ectopic kidney is an unusual and rare combination.
