What condition is indicated by classic cyanosis when resting but pink when crying?

The condition characterized by classic cyanosis when the infant is resting but appearing pink during crying is choanal atresia. This congenital defect involves the obstruction of the nasal passage, specifically where the nasal cavity connects to the throat. In infants with choanal atresia, the presence of bilateral obstruction results in cyanosis (a bluish discoloration of the skin due to low oxygen levels) when the infant is at rest, especially when they are tranquil or sleeping.

When the infant cries, the increased airflow through the mouth helps to alleviate the oxygen deprivation, causing the skin color to return to pink. This phenomenon is sometimes described as "cyanic when quiet, pink when crying." This clinical presentation is vital for early recognition, as choanal atresia can significantly affect respiratory function.

Other options do not exhibit these specific symptoms. Cephalohematoma involves a collection of blood between the skull and periosteum, without a significant effect on cyanosis. ROP stage I, or retinopathy of prematurity, does not cause changes in skin color based on activity levels but relates to the development of the retinal blood vessels. Strawberry hemangioma refers to a type of vascular birthmark that does not affect oxygenation status or cause
