Yellow nail syndrome

In yellow nail syndrome, nails thicken and grow slower. This results in the nails turning a yellowish color.

Nails affected by yellow nail syndrome might lack a cuticle and detach from the nail bed in places. Yellow nail syndrome may be a symptom of a lung disease, such as chronic bronchitis. Yellow nail syndrome also can be related to swelling of the hands, arms, feet and legs — a condition called lymphedema.
