title: Perioral pigmentation: what is your diagnosis?
abstract: Pigmented spots in the skin and mucosa (lentigines) can be found in various diseases called familial lentiginosis syndromes; Peutz-Jeghers syndrome (PJS) is one of them. It is characterized by the association of mucocutaneous melanin pigmentation and hamartomatous gastrointestinal polyps. Patients with PJS are at increased risk of intussusception and cancer development (gastrointestinal and non-gastrointestinal tumors). We present a 5-year-old girl with pigmented macules of perioral and perinasal skin, lips, and buccal mucosa and review lentiginoses and the surveillance of PJS.
