Alamjan Nematilaev was the surviving host of one of the very rare cases of Parasitic twin. In 2003, aged 7, his school doctor in Kazakhstan referred him to hospital after movements were detected in the boy's enlarged stomach. An operation intended to remove a cyst uncovered the foetus of Alamjan's identical twin brother, which had lived as parasitic growth inside the boy throughout his entire life. The foetus was comparatively highly developed, with hair, arms, fingers, nails, legs, toes, genitals, a head, and a vague approximation of a face. His story generated some worldwide media attention for a while, but his parents chose to tell him only that he had grown sick due to eating unwashed fruit to spare him unpleasant trauma.
