A New Case of Turner Syndrome with Early Pubertal Development
Abstract: Turner syndrome (TS) is a relatively common chromosomal disorder caused by complete or partial X monosomy. The most frequently observed karyotype, 45, X, arises more often by loss of the paternal X or Y chromosome in meiosis or in early embryogenesis than by loss of the maternal X chromosome. The main clinical features of TS are short stature, gonadal dysgenesis, and not to undergo pubertal development (e.g. primary amenorrhea). However, a few rare cases of TS have shown precocious puberty. Our case of a 9-year-old girl did not have any TS-specific clinical hallmarks, with the exception of short stature. She visited our clinic because of her pubertal development and short stature. In this report, we highlight the variability that can occur in patients with TS and emphasizes the need to carefully assess unusual growth patterns in any child, regardless of other underlying conditions.
