  • Soft Tissue Mass

    He developed soft tissue masses in the right heel and right elbow that were calcified or ossified on plain radiographs. MR imaging raised a suspicion of heterotopic ossification; thus, GNAS1 was analyzed. [ncbi.nlm.nih.gov]

  • Stiffness of the Lower Limbs

    In April 2001, a 52-yr-old woman, with no familial history of abnormal ossification, was admitted for pain and stiffness of the lower limbs. [academic.oup.com]

    She first experienced symptoms in 1985, with knee, calf and ankle pains, and later suffered from lower limb stiffness. [academic.oup.com]

  • Skin Lesion

    She is of small stature (0.4th centile) and started to develop skin lesions at the age of 9 months. These have been confirmed histologically as osteoma cutis. She is of normal intelligence and development and has no dysmorphic features. [ncbi.nlm.nih.gov]

    Biopsies of the skin lesions demonstrated osteoma cutis consistent with POH [48]. [gulfdoctor.net]

  • Subcutaneous Nodule

    Her father and father's aunt had subcutaneous nodules. At the age of 5 years, physical examination of the patient revealed ossified subcutaneous nodules and plaques on both upper limbs, the right side was predominantly affected. [ncbi.nlm.nih.gov]

  • Subcutaneous Mass

    Case 1: A 4-year-old boy with obesity, speech delay, and expanding subcutaneous masses on buttock/forearm. Physical exam revealed round facies and brachydactyly. [ncbi.nlm.nih.gov]

  • Calcinosis Cutis

    Biopsy results from the lesions showed calcinosis cutis superficially, with both endochondral and intramembranous bone formation in the deeper tissues. [ncbi.nlm.nih.gov]

  • Suggestibility

    Occasional reports of mild heterotopic ossification in Albright's hereditary osteodystrophy (AHO) and a recent report of two patients with AHO who had atypically extensive heterotopic ossification suggested a common genetic basis for the two disorders [ncbi.nlm.nih.gov]

  • Round Face

    PE at age 4 months included: length and weight 95%, a round face, short 4th metacarpals, and extensive subcutaneous ossifications of the lower limbs, buttocks, and back. [ncbi.nlm.nih.gov]

  • Irritability

    Subcutaneous ossifications that are superficial and well circumscribed may be surgically removed when they are large or cause local irritation, although they may recur [2]. [gulfdoctor.net]

Treatment: Currently, there are no effective treatments or prevention for POH. [iofbonehealth.org]

We hope to inform pediatricians and orthopedic surgeons to create more awareness of this disorder so that unnecessary treatments can be avoided and proper counseling offered. [ncbi.nlm.nih.gov]

The patient was advised physiotherapy to maintain range of motion and the parents were counseled regarding the prognosis of the disease. [ijoonline.com]

The genetics, diagnostic criteria, supporting clinical features, current management, and prognosis of POH are reviewed here, and emerging therapeutic strategies are discussed. [dovepress.com]

Treatment: Currently, there are no effective treatments or prevention for POH. [iofbonehealth.org]

TREATMENT: Standard Therapies: No effective treatments or preventions exist for POH. Areas of well-circumscribed heterotopic ossification may rarely be removed successfully; surgical removal of POH tissue has led to recurrence in most patients. [ifopa.org]

The protein produced from the GNAS gene is believed to play a key role in signaling pathways that help regulate the development of bone (osteogenesis), preventing bony tissue from being produced outside the skeleton. [ghr.nlm.nih.gov]

Prevention In patients at high risk for the development of heterotopic bone formation, there are several treatments that have been used to prevent the development of excess bone. [verywell.com]
