title: A rare association of hyperparathyroidism and Turner's syndrome--a case report.
abstract: We present the clinical, laboratory, radiological and pathological findings in the case and review the literature. Our patient, a 37-year-old woman of short stature, was referred because of musculoskeletal pain. After primary evaluation, she underwent treatment with calcium and vitamin D supplement with the diagnosis of osteomalacia in Turner's syndrome. The rise of serum calcium during medical therapy, which was an unusual finding, attracted the clinician's attention to another underlying disorder. Further evaluation revealed primary hyperparathyroidism due to an adenoma of the parathyroid gland. Even though this is a rare diagnosis, its presence should be considered in any patient with Turner's syndrome presenting with severe osteoporosis and a rise in serum calcium during treatment.
