Dominantly inherited isolated hyperparathyroidism: a syndromic association?
Dominantly inherited isolated hyperparathyroidism (DIIH) is rare in childhood. It may be the first biochemical abnormality in the multiple endocrine neoplasia type I (MEN I) and type II (MEN II) syndromes. Its clinical course is usually asymptomatic or of low morbidity. Radiographic examination is most often normal. We describe six members of a family with distinctive phenotype and DIIH. Limited systemic symptoms and severe radiographic osteitis fibrosa cystica were further unusual features in this family. The diagnosis of DIIH was made only after a 9-year-old girl developed hypercalcaemic crisis after a pathological femoral fracture. Distinctive phenotype, unusual clinical course and unparalleled radiographic changes suggest a not yet described syndromic association.
