ABSTRACT Albright hereditary osteodystrophy is a disorder comprising phenotypic characteristics of genetic origin, such as short stature, obesity, and brachydactyly. It is a rare disorder and is related to pseudohypoparathyroidism. Within dentistry, it may be associated with enamel hypoplasia and late eruption. Furthermore, due to neurological problems, these patients may impose behavioural difficulties during dental appointments. The present study aims to describe the case of a patient with a possible diagnosis of Albright hereditary osteodystrophy, presenting symptoms and limitations to dental management.

Progressive Osseous Heteroplasia

AbstractProgressive osseous heteroplasia (POH) is a condition of invasive heterotopic ossification. Reports of patients with mild POH with Albright hereditary osteodystrophy (AHO), specifically pseudohypoparathyroidism type Ia (PHP Ia) with hormonal resistance, suggest the possibility of a common molecular basis.A 4-year-old boy with obesity, speech delay, and expanding subcutaneous masses on buttock/forearm. Physical exam revealed round facies and brachydactyly. Blood tests showed normal Ca, P, Mg, 25-OH vitamin D levels but elevated parathyroid hormone (PTH) and thyroid-stimulating hormone (TSH). Abdominal computed tomography (CT) showed areas with calcifications in the subcutaneous tissue, fat, and muscle. Pathology of excised tissue revealed ossifications. Genomic study revealed noA 3-year-old boy with painful ossifications in the left lower extremity. Lab tests were notable for elevated PTH and high-normal TSH. The CT-scan showed subcutaneous/intramuscular calcifications. Genetic testing showedA 9-year-old boy with knee pain and subcutaneous ossifications in back and upper/lower extremity, causing significantly limited joint mobility. Lab tests were normal. The CT-scan showed areas corresponding to subcutaneous/intramuscular ossifications throughout torso and extremities, consistent with POH. There was noPatients with heterotopic ossifications present with a wide spectrum of disease. Although
