Isolated premature thelarche: A normal growth variant

Premature thelarche is frequently considered to be a normal variant of growth and development as it shows spontaneous remission in majority of cases. However, progression to precocious puberty is seen in up to 13% of cases. We present a case of 11-month-old female child with a history of progressive breast enlargement. Investigations revealed normal bone age and hormonal evaluation. This case emphasizes the importance of simple baseline investigations to differentiate precocious puberty and premature thelarche, thus ameliorating the parental anxiety.
