Leontiasis ossea, also known as leontiasis, lion face or lion face syndrome, is a rare medical condition, characterized by an overgrowth of the facial and cranial bones. It is not a disease in itself, but a symptom of other diseases, including Paget's disease , fibrous dysplasia , hyperparathyroidism and renal osteodystrophy .
Craniodiaphyseal dysplasia (CDD), also known as lionitis, is an extremely rare autosomal recessive bone disorder that causes calcium to build up in the skull, disfiguring the facial features and reducing life expectancy. These calcium deposits decrease the size of cranial foramina, and can decrease the circumference of the cervical spinal canal ...
In England in the 13th–19th centuries with life expectancy at birth rising from perhaps 25 years to over 40, expectation of life at age 30 has been estimated at 20–30 years, [166] giving an average age at death of about 50–60 for those (a minority at the start of the period but two-thirds at its end) surviving beyond their twenties.
Living among a small band of Neanderthals in what is now eastern Spain was a child, perhaps 6 years old, with Down syndrome, as shown in a remarkable fossil preserving traits in the inner ear ...
Beare–Stevenson cutis gyrata syndrome is a rare genetic disorder characterized by craniosynostosis (premature fusion of certain bones of the skull, sometimes resulting in a characteristic 'cloverleaf skull'; further growth of the skull is prevented, and therefore the shape of the head and face is abnormal) and a specific skin abnormality, called cutis gyrata, characterized by a furrowed and ...
Kleeblattschaedel is a rare malformation of the head where there is a protrusion of the skull and broadening of the face. [2] This condition is a severe type of craniosynostosis. [3] The condition can be both isolated or associated with other craniofacial dysostosises. [4] 85% of children with this condition have other anomalies. [5]
Cranio-lenticulo-sutural dysplasia (CLSD, or Boyadjiev–Jabs syndrome) is a neonatal/infancy disease caused by a disorder in the 14th chromosome. It is an autosomal recessive disorder, meaning that both recessive genes must be inherited from each parent in order for the disease to manifest itself.
Roberts syndrome, or sometimes called pseudothalidomide syndrome, is an extremely rare autosomal recessive genetic disorder that is characterized by mild to severe prenatal retardation or disruption of cell division, leading to malformation of the bones in the skull, face, arms, and legs. It is caused by a mutation in the ESCO2 gene. It is one ...
