Infantile hemangioma
Infantile hemangioma, also known as a strawberry mark or capillary hemangioma, is the most common benign tumor of infancy, growing rapidly for months then shrinking over years.
Infantile hypotonia-oculomotor anomalies-hyperkinetic movements-developmental delay syndrome
Infantile hypotonia-oculomotor anomalies-hyperkinetic movements-developmental delay syndrome, also called Baker-Gordon syndrome or BAGOS, is a rare autosomal dominant SYT1-related neurodevelopmental disorder with hypotonia, eye anomalies, movement disorders, delay, and EEG abnormality without epilepsy.
Infantile mercury poisoning
Infantile mercury poisoning, also called pink disease or infantile acrodynia (Feer disease, Swift disease), a rare childhood mercury intoxication causing pink, painful, desquamating extremities, sweating, and hypertension; historically caused by calomel teething powders and largely eliminated after their 1950s withdrawal.
Infantile multisystem neurologic-endocrine-pancreatic disease
