Platyspondyly development begins with generalised osteosclerosis, then subsequent interspersing sclerotic bands develop within vertebral bodies with normal bone density, showing radiolucency. Diagnosis
Medical diagnosis of DSS involves various examinations and evaluations. This usually includes physical examinations, medical history evaluations, assessment of signs and symptoms, laboratory tests and image studies. Biopsy may also be required if necessary.Signs and symptoms of DSS show similarities with multifarious disorders and diseases such as osteosclerosis, H syndrome and Pyle disease. As such, it is likely that DSS is consequently incorrectly identified as osteopertrosis. Therefore, additional tests may be performed in order to arrive at a definitive diagnosis. Prognosis and management
Overall the disease has a poor prognosis, with treatment mainly focusing on palliation and comfort care.As the mechanism and clinical course of DSS remains unclear, definitive treatment is not available for patients. Bone marrow transplant may improve skeletal abnormalities, however it is improbable the transplant will ameliorate the unexplained neurological deteriorations. In addition, the surgery may not be suitable for every patients as the underlying genetic cause of the disease varies amongst patients. Advice of control and reduction in excessive calcium intake may be recommended by physicians to ensure circulating levels of parathyroid hormones are normal to induce and maintain bone resorption. == References ==
Chondrodermatitis nodularis chronica helicis is a small, nodular, tender, chronic inflammatory lesion occurring on the helix of the ear, most often in men. : 610  it often presents as a benign painful erythematous nodule fixed to the cartilage of the helix or antihelix of the external ear. Although the exact cause of the condition is unknown, it has been linked to head pressure on the ear while sleeping. Treatment options include the use of pressure-relieving devices or, in cases where that is not an option, surgery. See also
