Background:
Sebaceous hyperplasia is a benign proliferation of the sebaceous gland. Previous treatment options have included isotretinoin, destructive modalities, and pulsed-dye laser.
Objective:
To evaluate the efficacy of a 1450-nm diode laser for the treatment of sebaceous hyperplasia.
Methods:
Ten patients with sebaceous hyperplasia were treated one to five times with a 1450-nm diode laser. Fluences of 16 to 17 J/cm2 were used, with cooling durations of 40 to 50 ms. Patients and physicians evaluated treated lesions for improvement. Measured areas of treated lesions were also recorded.
Results:
In most cases, patients and physicians rated improvement as "very good" or better. After two to three treatments, 84% of lesions shrunk greater than 50%, and 70% shrunk greater than 75%. Adverse effects were unusual; one atrophic scar and one case of transient hyperpigmentation were observed.
Conclusion:
The 1450-nm diode laser is effective and safe for the treatment of sebaceous hyperplasia.
