ABSTRACT
Introduction:
Mc Cune-Albright syndrome (SMA, by its acronym in Spanish) is a rare entity associated with polyostotic fibrous dysplasia, with the presence of brown spots with milk and also with endocrine hyperfunction. The most common hormonal alteration is precocious puberty. SMA is caused by GNAS1 gene´s activator mutations.
Objective:
Describe the clinical characteristics of a patient with Mc Cune-Albright syndrome with precocious puberty.
Methods:
A review of the medical history was carried out as a primary source and all the clinical, biochemical, imaging and genetic elements that made up the comprehensive assessment of the patient were incorporated.
Case presentation:
A rare case of Mc Cune-Albright syndrome occurs in a seven-year-old girl with Tanner II-III breasts, vaginal bleeding, axillary and pubic hair, brown spots with milk and bone lesions. She is treated with tamoxifen, which has managed to keep the progression of pubertal development slow.
Conclusions:
Although this entity is benign in nature and the prevalence is extremely low, early pubertal onset and the compromise of the final size can have a psychological impact on the quality of life and normal development of the individual.
