Virchow-Seckel syndrome

Virchow-Seckel syndrome (also known as bird-headed dwarfism, Harper's syndrome or Seckel dwarfism) is a syndrome of unknown etiology, characterized by intrauterine growth retardation and postnatal dwarfism with a small head, narrow birdlike face with a beaklike nose, large eyes with an antimongoloid slant, receding mandible, and mild mental retardation. It is very rare.

The syndrome was named after Rudolf Virchow and Helmut Paul George Seckel (American physician, 1900–1960).
