Sebaceous hyperplasia occasionally also occurs on the chest, areola, mouth or vulva. They often have a central indentation.
Treatment & Prevention
------------------------------------------
--------------------------------------
The cause is unknown and tends to run in families. While no treatment is necessary, they can be treated by:
Tretinoin cream or gel used daily will reverse the condition slowly overtime and also help keep the condition from worsening.
Accutane will reverse sebaceous hyperplasia, but new lesions will develop after stopping the medication unless you also use tretinoin cream regularly.
TCA chemical peels will also reverse sebaceous hyperplasia, but new lesions will occur slowly after treatment.
They can be destroyed with electrocautery or laser.
Prognosis
------------------------------------------
--------------------------------------
Lesions of sebaceous hyperplasia are benign, with no known potential for malignant transformation.
