Follow-up

Complications

  • Secondary bacterial infections can occur in traumatized lesions in individuals with keratosis pilaris.

Prognosis

A study performed by Poskitt demonstrated the following course:2

  • The condition dramatically improves in approximately 35% of patients, usually by late adolescence (mean age of improvement is 16 y).
  • The condition remains unchanged from the time of diagnosis in approximately 43% of patients.
  • Approximately 20% of patients experience a worsening of symptoms over time.
  • Approximately 50% experience a worsening of symptoms during wintertime, but only 60% of those who worsen improve over summertime.

Patient Education

  • Reassurance and general skin care are the most important recommendations the physician can offer.

Miscellaneous

Special Concerns

  • Frequency of keratosis pilaris is increased in individuals who have autosomal dominant ichthyosis vulgaris.
  • Recent reports indicate that keratosis pilaris is most likely a phenotype of ichthyosis vulgaris.6
  • An association between keratosis pilaris and Noonan syndrome and Down syndrome is also reported.
