This shape is due to the blockage/occlusion of small arteries.Individuals may be diagnosed with the benign form if only the papules are present. However, an individual may be diagnosed with the malignant form if involvement of other organs like the lungs, intestine and/or central nervous system occurs. The malignant, or systematic form of this condition may suddenly develop even after having papules present for several years. In order to quickly diagnose this shift to the malignant variant of the disease, it is important for individuals to have consistent follow-up evaluations. In these evaluations, depending on which organs are suspected to be involved, the following procedures and tests may be conducted: skin inspection, brain magnetic resonance tomography, colonoscopy, chest X-ray, and/or abdominal ultrasound. Treatment
Due to the lack of knowledge around the underlying mechanism of malignant atrophic papulosis, an effective treatment method has not been developed. Treatment for this condition is symptomatic. However, several treatment methods have been tested and are still being developed as more information regarding the condition is found. Fibrinolytic and immunosuppressive therapeutic regimens were tested and found to be mostly unsuccessful as treatment methods.After treating conditions comorbid with Degos disease, physicians have recently found improvement in symptoms with the use of eculizumab and treprostinil. Discovered by dermatopathologist, Cynthia Magro, response to eculizumab is often immediate and dramatic, but has been of limited duration and is expensive, needing to be infused every 14 days.
Degos disease, also known as Köhlmeier-Degos disease or malignant atrophic papulosis, is an extremely rare condition caused by blockage of arteries and veins. Individuals with this condition will develop papules. Those diagnosed with this disease may also develop complications due to impairment of internal organs. The exact underlying mechanism is still unknown, and an effective treatment is still being developed. There are fewer than 50 living patients presently known worldwide, and fewer than 200 reported in medical literature. However, many individuals may go undiagnosed due to rarity of the disease. Most individuals develop symptoms between the ages of 20–50; however, cases outside of this age range have been reported as well. Symptoms and signs
The characteristic symptom of Degos disease is the development of papules. Initially, individuals may have skin lesions or rashes, but they will proceed to develop distinct bumps, or papules. Papules are circular in shape, have a porcelain-white center and red border. As papules age, the white centers will skin in and only the border will remain raised. Typically, papules range from 0.5 to 1 cm in width. Papules appear on the trunk and upper extremities and are not found on the individuals palms, soles, scalp, or face.Symptoms vary, depending on whether an individual has the benign variant or malignant variant of the disease. Both the benign and malignant forms have development of the characteristic papules. Individuals with the benign form will have the typical papules persisting anywhere from a few years to throughout their whole lives.
