Introduction:

the excess of biological hormonal activity of parathyroid origin is a frequent reason for consultation in endocrinological practice, although referrals from services such as nephrology, orthopedics or maxillofacial surgery are also referred due to the varied clinical presentations of the disease.

Case presentation:

a 34-year-old female patient with a personal medical history of chronic renal failure. He went to the institution for presenting changes in his body appearance, especially at the level of the facial massif. The physical examination showed ostio-myo-articular alterations. The pelvic X-ray showed decreased bone density and diastasis of the pubic symphysis. Two-stage parathyroid scan detected parathyroid hyperplasia. Computed tomography of the skull showed marked bone destruction and resorption. Tertiary hyperparathyroidism was suggested.

Conclusions:

tertiary hyperparathyroidism is one of the less frequent causes of parathyroid hyperfunction; It can occur as a consequence of a renal disorder that is perpetuated over time. Timely diagnosis and treatment decreases the incidence of comorbidities. Parathyroidectomy represents the treatment of choice, with high cure rates.
