Treatment of Acanthosis nigricans of the axillae using a long-pulsed (5-msec) alexandrite laser.
BACKGROUND
Acanthosis nigricans of the axillae is a common cutaneous disorder that is difficult to treat.


OBJECTIVE
The objective was to assess the efficacy and safety of a long-pulsed alexandrite laser (5 msec) in the treatment of acanthosis nigricans of the axillae.


METHODS
A single axilla was treated using the long-pulsed alexandrite laser. Ten sessions were required, at fluences of 16 to 23 J/cm2 using either 10- or 12.5-mm spot sizes. The untreated axilla served as a control.


RESULTS
Greater than 95% clearance was achieved after seven sessions. There was no recurrence after 2 years. The untreated axilla was unchanged.


CONCLUSIONS
The long-pulsed alexandrite laser can effectively and safely treat acanthosis nigricans of the axillae.
