Multiple lentigines syndrome
Alternative namesLeopard syndrome
Multiple lentigines syndrome is an inherited disorder characterized by an increased number of lentigines (freckle-like spots).
Causes, incidence, and risk factors
Multiple lentigines syndrome is inherited as an autosomal dominant trait. Affected people have large numbers of lentigines (freckle-like lesions present from birth and somewhat darker than true freckles) as the most obvious sign. These are located mostly on the trunk and neck. Affected people also have wide-set eyes (hypertelorism), prominent ears, nerve deafness (partial), and cafe-au-lait spots (light brown birthmarks).
Additional findings include mild pulmonic stenosis and changes in the ECG . Affected people may have abnormal genitalia ( cryptorchidism ), hypogonadism , or delayed puberty.
Signs and testsA physical examination may show signs of mild pulmonic stenosis (obstruction of the pulmonic heart valve) and obstructive cardiomyopathy .
TreatmentTreatment is directed toward the correctable problems. The degree of hearing loss must be determined and appropriate hearing aids supplied. Intervention at the expected time of puberty may be necessary in order precipitate the normal changes of puberty.
Expectations (prognosis)Most patients adjust very well with proper attention to their specific problems.
