Periostitis, also known as periostalgia, is a medical condition caused by inflammation of the periosteum, a layer of connective tissue that surrounds bone. [1] The condition is generally chronic and is marked by tenderness and swelling of the bone and pain.
Hypertrophic osteoarthropathy is one of many distant effect disorders due to cancer, with lung cancer being the most common cause but also occurring with ovarian or adrenal malignancies. A distant effect disorder, or a paraneoplastic syndrome , affects distant areas and thus is not related to local compression or obstruction effects from the tumor.
Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
When a person has primary bone cancer, the cancer cells are bone cells that have become cancerous. According to the NHS , around 550 cases of primary bone cancer are diagnosed each year in the UK.
Since PGE 2 is likely to be involved in periosteal bone formation and acroosteolysis, this is why these drugs can alleviate the polyarthritis associated with PDP. [4] In addition, NSAIDs and corticosteroids decrease formation of inflammatory mediators, reducing inflammation and pain. [30]
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
One theory is that hypertrophic osteopathy is caused by increased blood flow to the ends of the legs, overgrowth of connective tissue, and then new bone formation surrounding the bones. [6] This is secondary to nerve stimulation by the lung disease. The condition may reverse if the lung mass is removed or if the vagus nerve is cut on the ...
Garre's sclerosing osteomyelitis is a type of chronic osteomyelitis also called periostitis ossificans and Garré's sclerosing osteomyelitis. It is a rare disease. [1] It mainly affects children and young adults. [2] It is associated with a low grade infection, which may be due to dental caries (cavities in the teeth). [citation needed]
