Café au lait spots in coloured and Indian children.

A survey of 270 Indian and 143 Coloured children was conducted to determine the prevalence of café au lait spots and axillary freckling, these both being features of neurofibromatosis. Spots of more than 0,5 cm in diameter occurred in approximately 40% of the children and freckling in over 4%. One definite case and 2 suspected cases of neurofibromatosis were detected.
