Lentigo.

A lentigo is a small pigmented macule with a sharply circumscribed border. There are multiple clinical and etiologic forms. Lentigines are often initially identified shortly after birth, although they may appear later in childhood. Certain varieties are associated with systemic abnormalities. Histologic findings include epidermal hyperplasia with increased pigmentation of the basal layer.

Usefulness of diagnostic criteria of tuberous sclerosis complex in pediatric patients.

The Tuberous Sclerosis Complex 1998 Consensus Conference clinical criteria represent an important advance in the diagnosis of tuberous sclerosis complex. Since many findings regarded as highly specific for tuberous sclerosis complex are not apparent until late childhood or adulthood, refinements by age may prove of value. We have stratified 106 children into five age groups (0 to 2 years of age, above 2 to 5 years, above 5 to 9 years, above 9 to 14 years, and above 14 to 18 years). Physicians should be alerted as to the frequency of the criteria in different stages of children.

Diagnostic value of clinical features and supplementary investigations in tuberous sclerosis in children.

The author evaluates the usefulness of clinical features and some supplementary investigations in diagnosis of tuberous sclerosis in children. 52 children ranging in age from 1 month to 14 years took part in the study. Usually depigmented naevi were the first sign of tuberous sclerosis and were seen in 98% of affected children. Epileptic seizures occurred in 96% of patients, mostly during the first year of life. Axial computed tomography of brain seems to be very helpful in diagnosis of tuberous sclerosis in every age. Multiple periventricular calcifications were found in 98% of children. Two-dimensional echocardiography was especially useful in infants and children below 2 years of age. Retinal hamartomas were found in 25% of children with tuberous sclerosis. In some cases these changes were revealed during the first year of age. Abnormal EEGs were found in 90% of recordings. The EEGs tended to improve with increasing age. In 25% of children one of parents was affected by tuberous sclerosis. The careful skin examination of both parents can be especially helpful in children with doubtful diagnosis of tuberous sclerosis.
