disease is a very rare skeletal condition of uncertain etiology, characterized by the uncontrolled proliferation of distended,
thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement of bone with angiomas and/or
fibrosis.  Because of the loss of the affected bone, the condition has been referred to as disappearing bone disease, vanishing
bone disease, and massive osteolysis. In medical terminology osteolysis means: bone (osteo) breaking down or destruction (lysis).
symptoms of Gorham’s disease vary depending on the bones involved. It may affect any part of the skeleton, but the most
common sites of disease are the shoulder, skull, pelvic girdle, jaw, ribs, and spine.,   
some cases there are no symptoms until a fracture occurs either spontaneously or following minor trauma, such as a fall. There
may be an acute onset of localized pain and swelling. More commonly there is pain of no apparent cause that increases in frequency
and intensity over time and may eventually be accompanied by weakness and noticeable deformity of the area. The rate of progression
is unpredictable and the prognosis can be difficult. The disease may stabilize after a number of years, go into spontaneous
remission, or, in cases involving the chest and upper spine, prove fatal. Recurrence of the disease following remission can
also occur. Involvement of the spine and skull base may cause a poor outcome from neurological complications. In many cases,
the end result of Gorham’s disease is severe deformity and functional disability.  
such as difficulty breathing and chest pain may be present if the disease is present in the ribs, scapula, or thoracic vertebrae.
These may indicate that the disease has spread from the bone into the chest cavity. The breathing problems may be misdiagnosed
as asthma, because the damage done to the lungs can cause the same types of changes to lung function testing that are seen
in asthma. Extension of the lesions into the chest may lead to the development of chylous pleural and pericardial effusions. Chyle
is rich in protein and white blood cells that are important in fighting infection. The loss of chyle into the chest can have
serious consequences, including infection, malnutrition, and respiratory distress and failure. These complications or their
symptoms, such as difficulty breathing, chest pain, poor growth or weight loss, and infection have sometimes been the first
indications of the condition.  
To date, the specific etiology of Gorham’s disease remains undefined.
Bone mass and strength
are obtained and maintained through a remarkable process of bone destruction and replacement that occurs at the cellular level
throughout a person’s life. Cells called osteoclasts secrete enzymes that dissolve old bone, allowing another type of
cells called osteoblasts to form new bone. Except in growing bone, the rate of breakdown equals the rate of building, thereby
maintaining bone mass. In Gorham’s disease that process is clearly disrupted.     
and Stout found that vascular anomalies always occupied space that normally would be filled with new bone and speculated that
the presence of angiomatosis may lead to chemical changes in the bone.  Gorham and others speculated that such a change in the bone chemistry might cause an imbalance in the rate of osteoclast
activity to osteoblast activity such that more bone is dissolved than is replaced. Beginning in the 1990’s there are reports of elevated levels of a protein called interleukin-6 (IL-6) being detected
in patients with the disease, leading some to suggest that increased levels of IL-6 and vascular endothelial growth factor
(VEGF) may contribute to the chemical changes Gorham and others believed were the cause of this type of osteolysis. 
1999 Möller and colleagues concluded, “The Gorham-Stout syndrome may be, essentially, a monocentric bone disease with a focally increased
bone resorption due to an increased number of paracrine – or autocrine – stimulated hyperactive osteoclasts. The
resorbed bone is replaced by a markedly vascularised fibrous tissue. The apparent contradiction concerning the presence or
absence or the number of osteoclasts, may be explained by the different phases of the syndrome.” They further stated
that their histopathological study provided good evidence that osteolytic changes seen in Gorham’s disease are the result
of hyperactive osteoclastic bone. However, others have concluded that lymphangiomatosis and Gorham’s disease should
be considered as a spectrum of disease rather than separate diseases.
there is consensus that Gorham’s is caused by deranged osteoclastic activity,    there is not yet conclusive evidence as to what causes this deranged behavior to begin.
In 1983 Heffez and colleagues published a case report in which they suggested eight criteria for a definitive diagnosis of Gorham’s disease:
with the presence of angiomatous tissue
Absence of cellular atypia
Minimal or no osteoblastic response or dystrophic calcifications
Evidence of local bone progressive
Non-expansile, non-ulcerative lesions
No involvement of viscera
Osteolytic radiographic pattern
Negative hereditary, metabolic, neoplastic, immunologic, or infectious etiology.
In the early
stages of the disease x-rays reveal changes resembling patchy osteoporosis. As the disease progresses bone deformity occurs
with further loss of bone mass and, in the tubular bones (the long bones of the arms and legs), a concentric shrinkage is
often seen which has been described as having a “sucked candy” appearance. Once the cortex (the outer shell) of
the bone has been disrupted, vascular channels may invade adjacent soft tissues and joints. Eventually, complete or near-complete
resorption of the bone occurs and may extend to adjacent bones, though spontaneous arrest of bone loss has been reported on
occasion. Throughout this process, as the bone is destroyed it is replaced by angiomatous and/or fibrous tissue.    
Gorham’s disease is not recognized until a fracture occurs, with subsequent improper bone healing. The diagnosis essentially
is one of exclusion and must be based on combined clinical, radiological and histopathological findings. X-rays, CT, MRI, ultrasound, and nuclear medicine (bone scans) are all important tools in the diagnostic workup and
surgical planning, but none have the ability alone to produce a definitive diagnosis. Surgical biopsy with histological identification
of the vascular or lymphatic proliferation within a generous section of the affected bone is an essential component in the
diagnostic process.  
of the disease requires a high index of suspicion and an extensive workup. Because of its serious morbidity, Gorham’s
must always be considered in the differential diagnosis of osteolytic lesions.
Treatment and Management
Treatment of Gorham’s disease is for the most part palliative and limited to symptom management.
Sometimes the bone destruction
spontaneously ceases and no treatment is required. But when the disease is progressive, aggressive intervention may be necessary.
Duffy and colleagues reported that some 17% of patients with Gorham’s disease in the ribs, shoulder, or upper spine experience extension
of the disease into the chest, leading to chylothorax with its serious consequences, and that the mortality rate in this group
can reach as high as 64% without surgical intervention.
A search of the medical literature reveals multiple case reports of interventions, with varying rates
of success as follows:
(heart & lung): Pleurodesis, ligation of thoracic duct, pleurperitoneal shunt, radiation therapy, pleurectomy, surgical
resection, thalidomide, Interferon alpha 2b, TPN nutrition, thoracentesis, medium chain triglyceride and high protein diet,
chemotherapy, sclerotherapy, transplantation.
SKELETON: Interferon alpha 2b, bisphosphonates (i.e. pamidronate),
surgical resection, radiation therapy, sclerotherapy, percutaneous bone cement, bone grafts, prosthesis, surgical stabilization,
date, there are no known interventions that are consistently effective for Gorham’s and all reported interventions are
considered experimental treatments for Gorham’s, though many are routine for other conditions. Some patients may require
a combination of these approaches. Unfortunately, some patients will not respond to any intervention.
Gorham’s disease is
extremely rare and may occur at any age, though it is most often recognized in children and young adults. It strikes males
and females of all races and exhibits no inheritance pattern. The medical literature contains case reports from every continent.
Because it is so rare, and commonly misdiagnosed, it is not known exactly how many people are affected by this disease. The
literature frequently cites that fewer than 200 cases have been reported, though there is consensus building that there are
many more cases around the world than have been reported.
The first known report of the condition came in 1838 in an article
titled “A Boneless Arm” in what was then The Boston Medical and Surgical Journal, now The New England Journal
of Medicine. It is a brief but fascinating report chronicling the case of Mr. Brown who had, in 1819 at age 18 years, broken his
right upper arm in an accident. The patient suffered two subsequent accidents, which fractured the arm twice more “before
the curative process had been completed.” At the time of the report in 1838 the patient was reported as having remarkable
use of the arm, in spite of the humerus bone having apparently disappeared—x-rays did not yet exist. Thirty-four years
later, in 1872, a follow-up report was published in the same journal, following Mr. Brown’s death from pneumonia at
the age of 70 years. The patient had requested the arm “be dissected and preserved for the benefit of medical science” and this
report contains a detailed pathological description of the arm and shoulder. Abnormalities of the remaining bones of the arm
and shoulder are noted and the authors report that the arteries, veins, and nerves appeared normal. There is no mention of
lymphatic vessels. Though several reports of similar cases were published in the interim, more than 80 years would pass before
another significant report of the condition appeared in the medical literature.
Both born in 1885, Lemuel Whittington Gorham, MD, and Arthur Purdy
Stout, MD, had long, distinguished careers in medicine and shared a lifelong interest in pathology.   Dr. Gorham practiced and taught medicine and oncology and from the mid-1950’s through the early 1960’s
conducted and reported the classical clinicopathological investigations of pulmonary embolism. During this time period he
also authored several case series on osteolysis of bone. Dr. Stout began his career as a surgeon and became a pioneer in tumor
pathology, publishing Human Cancer in 1932. This work became the model for the Atlas of Tumor Pathology project, which Stout
oversaw as Chairman of the National Research Council in the 1950s. In his later years, Dr. Stout embarked on a systematic
study of soft tissue tumors in children and was among the first to link cigarette smoking to lung cancer.
In 1954 Gorham and three others published
a two case series, with a brief review of 16 similar cases from the medical literature, that advanced the hypothesis that
angiomatosis was responsible for this unusual form of massive osteolysis. That same year Gorham and Stout presented to the American Association of Physicians their paper (in abstract form),
“MASSIVE OSTEOLYSIS (ACUTE SPONTANEOUS ABSORPTION OF BONE, PHANTOM BONE, DISAPPEARING BONE): Its Relation to Hemangiomatosis.” The paper was published in its entirety in October 1955 in The Journal of Bone and Joint Surgery, concluding that:
1. There now exists the
basis for a new syndrome which is supported by a remarkable similarity of clinical and [x-ray] findings in twenty-four cases,
and by an equally convincing similarity of the histological picture in eight of these, which we have personally studied.
2. However it is accomplished,
the progressive osteolysis is always associated with an angiomatosis of blood and sometimes of lymphatic vessels, which seemingly
are responsible for it. The most typical presentation is that of osteolysis of a single bone or the bones connected by a shared
joint, such as the shoulder. Although the disease can attack any bone, the shoulder is one of the most commonly involved areas,
along with the skull and pelvic girdle. Spontaneous fractures are common and may be the first sign of the disease. A hallmark of the disease is the lack of bone healing following fracture.
