Abstract
Peutz-Jeghers syndrome (PJS) is a rare, autosomal dominant disease where there is
a mutation in the tumor suppressor gene, with a greater predisposition to
neoplasms, especially of the gastrointestinal tract. The first manifestations
begin during childhood with the presence of mucocutaneous melanosis and, later,
gastrointestinal hamartomatous polyps. We describe a case of a young woman whose
initial PJS manifestation started during her childhood with cutaneous melanosis.
Three sessions with the Q-switched 1064nm Nd:YAG and 532nm KTP lasers were
performed to treat the melanosis with excellent results and without
recurrence.
