Mosaic Warts
• Mosiac warts typically require multiple treatments and less aggressive
parameters.
• Do NOT treat the entire mosaic wart area in one session.
o Only treat the darker/thicker area, usually near the center of the wart.
o Do NOT overlap pulses. Place pulses adjacent to one another or
spaced out.
o Cool the treatment area in between pulses.
• At each subsequent visit, repeat the treatment steps.
Endpoint
• Check for the endpoint after the first pulse.
• The desired endpoint is a slight ashen color that should occur immediately
after the pulse.
o The color change may be subtle.
o If the surrounding area becomes white or edematous, it was probably
over-treated and should be treated as a wound.
• If the endpoint is not reached:
o Increase the fluence by 5 J/cm
2
and shorten the pulse duration by the
minimum amount until you reach the endpoint.
o Cool the treatment area in between pulses.
o Repeat the treatment steps detailed above.
• Immediate post cooling with a cold gel pack, Zimmer, etc. may be used for patient
comfort.
POST-TREATMENT CARE
• Warts usually have a black or crusty appearance within 24 hours after treatment.
• You may apply an ointment of choice and non-stick dressing for patient
comfort.
• If a blister develops, treat it as a wound.
• Treated tissue usually sloughs within 1-4 weeks.
• Deep tissue injury and prolonged wound healing may occur.
• More than 1 treatment may be required (4-6 weeks apart).
