    Growth hormone (GH) - insulin like growth factor 1 (IGF-1) axis hyperactivity on bone fibrous dysplasia in McCune-Albright Syndrome.
    Clin Endocrinol (Oxf) 2018 Apr 19. Epub 2018 Apr 19.
    Section on Skeletal Disorders and Mineral Homeostasis, NIDCR, NIH, Bethesda, USA.
    Context: In fibrous dysplasia (BFD) normal bone and bone marrow are replaced by fibro-osseous tissue, leading to fracture, deformity and pain. BFD may be isolated, or in association with cutaneous hyperpigmentation and/or hyperfunctioning endocrinopathies, termed McCune-Albright syndrome (MAS). GH hypersecretion has been described in 10-20% of MAS-BFD patients. Read More

    Bilateral Tibial Fibrous Dysplasia in a Pediatric Patient treated with Intramedullary Nailing.
    P R Health Sci J 2018 Mar;37(1):58-61
    Department of Orthopedic Surgery, School of Medicine, University of Puerto Rico, Medical Sciences Campus, San Juan, PR.
    Fibrous dysplasia is a benign developmental disorder of bone in which fibrous connective tissue containing abnormal bone with irregular trabeculae replaces normal cancellous bone. It may affect 1 (monostotic) or multiple bones (polyostotic). Polyostotic disease is the less common of the 2, occurring in only 20 to 25% of fibrous dysplasia patients and tending to affect those who are younger than 10 years of age; patients having this form tend to experience bone enlargement beyond normal skeletal maturation, which can cause pain, progressive damage, and increased risk of pathological fracture.

    Pathologisches Institut, Klinikum Region Hannover, Haltenhoffstraße 41, 30167, Hannover, Deutschland.
    Fibrous dysplasia of bone is a connatal but not hereditary disease with monostotic or polyostotic manifestations and may be associated either with the extraskeletal disease McCune-Albright syndrome or with myxoma of the skeletal muscle, termed Mazabraud syndrome.The confirmation of recurrent chromosomal aberrations may lead to the conclusion that fibrous dysplasia is a neoplasia rather than a dysplastic skeletal disease.The primary cause of all forms of the described diseases is the activating GNAS mutation, which is detectable in almost all lesions.

    Constitutive stimulatory G protein activity in limb mesenchyme impairs bone growth.

    Endocrine Unit, Department of Medicine, Massachusetts General Hospital and Harvard Medical School, Boston, MA 02114, USA. Electronic address:
    GNAS mutations leading to constitutively active stimulatory G protein alpha-subunit (Gsα) cause different tumors, fibrous dysplasia of bone, and McCune-Albright syndrome, which are typically not associated with short stature. Enhanced signaling of the parathyroid hormone/parathyroid hormone-related peptide receptor, which couples to multiple G proteins including Gsα, leads to short bones with delayed endochondral ossification. It has remained unknown whether constitutive Gsα activity also impairs bone growth. Read More

    Molecular Medicine Research Center, College of Medicine, Chang Gung University, Taoyuan 333, Taiwan.
    McCune-Albright syndrome (MAS) is characterized by the triad of precocious puberty, café au lait pigmentation, and polyostotic fibrous dysplasia (FD) of bone, and is caused by post-zygotic somatic mutations-R201H or R201C-in the guanine nucleotide binding protein, alpha stimulating (GNAS) gene. In the present study, a novel peptide nucleic acid (PNA) probe with fluorescent labeling was designed to detect trace amounts of somatic mutant in a single tube reaction.

    Section on Skeletal Disorders and Mineral Homeostasis, Craniofacial and Skeletal Diseases Branch, National Institute of Dental and Craniofacial Research, National Institutes of Health, Bethesda, MD, USA.
    In fibrous dysplasia/McCune-Albright syndrome (FD/MAS), bone and bone marrow are, to varying degrees, replaced by fibro-osseous tissue typically devoid of hematopoietic marrow. Despite the extensive marrow replacement in severely affected patients, bone marrow failure is not commonly associated with FD/MAS. We present a 14-year-old girl with FD/MAS, who developed pancytopenia and extramedullary hematopoiesis (EMH) with no identified cause, in the setting of iatrogenic thyrotoxicosis and hyperparathyroidism.

    Bisphosphonate-induced zebra lines in fibrous dysplasia of bone: histo-radiographic correlation in a case of McCune-Albright syndrome.

    Dental Physical Sciences, Queen Mary University of London, London, E1 4NS, UK.
    Bisphosphonates (BPs) are currently used in the treatment of diverse bone diseases including fibrous dysplasia of bone (FD). In pediatric patients, a radiographic consequence of cyclical administration of BPs is the development of apo-, epi-, and meta-physeal sclerotic bands, otherwise known as zebra lines, which result from the temporary inhibition of osteoclastic activity at the time of drug treatment. We report here on a child with McCune-Albright syndrome (FD in addition to hyperfunctioning endocrinopathies and skin hyperpigmentation) treated with cyclical intravenous infusions of pamidronate in which conventional radiography, contact microradiography, histology, and backscattered electron image analysis demonstrated that zebra lines formed only where bone was normal, were arrested at the boundary between FD-unaffected and FD-affected bone where bone is sclerotic, and were absent within the undermineralized FD bone.

    To develop consensus on improving the management of patients, we convened an international workshop involving patients, clinicians, and researchers. Key findings included the diagnostic delay and variability in subsequent management with agreement to develop an international natural history study. We now invite other stakeholders to join the partnership. Read More

    Hypothyroidism in McCune-Albright Syndrome and Role of Bone Scan in Management of Fibrous Dysplasia: An Unusual Case Scenario with Review of Literature.
    Indian J Nucl Med 2017 Jan-Mar;32(1):25-29
    Department of Nuclear Medicine, SGPGIMS, Lucknow, Uttar Pradesh, India.
    The McCune-Albright syndrome (MAS) is a triad of café-au-lait skin pigmentation, precocious puberty (PP), and polyostotic fibrous dysplasia of bone (FD). In general, FD seems to be the most common component of MAS but very rarely precocious puberty can be found in association with café-au-lait skin pigmentation in the absence of FD (about 1% of the cases). Therefore, a more clinically relevant definition of MAS is fibrous dysplasia of bone (FD) and at least one of the typical hyperfunctioning endocrinopathy and/or café-au-lait spots, with almost any combination possible.

    We report on a 47-year-old woman with unilateral fibrous dysplasia and three intramuscular masses. Medical imaging revealed possible intramuscular myxomas, so that the suspected diagnosis was Mazabraud syndrome. After biopsy, the suspected diagnosis was verified by histology and molecular pathology. Read More

    Mucinous Cystadenoma in Children and Adolescents.
    J Pediatr Adolesc Gynecol 2017 Aug 16;30(4):495-498. Epub 2017 Feb 16.
    Children's National Medical Center, MedStar Washington Hospital Center, Washington, DC.
    Study Objective: Mucinous cystadenomas (MCAs) are benign epithelial ovarian tumors that occur rarely in children and adolescents. Because children and adolescents typically have their childbearing years ahead of them, conservative therapy is indicated. However, there is concern that ovarian cystectomy might be associated with significant recurrence risk in patients with MCA. Read More

    Patients with McCune-Albright syndrome have a broad spectrum of abnormalities in the gastrointestinal tract and pancreas.
    Virchows Arch 2017 Apr 10;470(4):391-400. Epub 2017 Feb 10.
    Department of Pathology, Johns Hopkins University School of Medicine, Baltimore, MD, USA.
    McCune-Albright Syndrome (MAS) is a rare sporadic syndrome caused by post-zygotic mutations in the GNAS oncogene, leading to constitutional mosaicism for these alterations. Somatic activating GNAS mutations also commonly occur in several gastrointestinal and pancreatic neoplasms, but the spectrum of abnormalities in these organs in patients with MAS has yet to be systematically described. We report comprehensive characterization of the upper gastrointestinal tract in seven patients with MAS and identify several different types of polyps, including gastric heterotopia/metaplasia (7/7), gastric hyperplastic polyps (5/7), fundic gland polyps (2/7), and a hamartomatous polyp (1/7).
