An unusual case of Peutz-Jeghers syndrome in an infant.

An 11-month-old girl had an unusual history of colocolonic intussusception associated with polyps that prolapsed through the rectum. Several months thereafter, characteristic brownish-black pigment spots of the lips were noted. The histologic appearance of the polyps was consistent with that of the Peutz-Jeghers syndrome. To our knowledge, this is the youngest reported case of symptomatic Peutz-Jeghers syndrome.
