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. 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. Treprostinil use has been reported to result in clearing of gastrointestinal and central nervous system findings as well as clearing of cutaneous lesions, but reports are limited. Treprostinil may be more effective than other vasodilators because it may also increase the population of circulating endothelial cells, allowing angiogenesis. A 46-year-old male patient was diagnosed with the malignant, systemic form of the disease and was severely ill. The diagnosing dermatopathologist, Cynthia Magro MD, identified the presence of C5b-9 complexes in the involved vessels of the skin biopsy. For treatment of the thrombotic microangiopathy in this patient, she suggested the use of eculizumab, a humanized monoclonal antibody drug developed by Alexion Pharmaceuticals and approved by the Food and Drug Administration for treatment of Paroxysmal nocturnal hemoglobinuria. The patient experienced a dramatic improvement in his condition. Lee Shapiro MD and Aixa Toledo-Garcia MD at Albany Medical College learned of the success with the adult patient, and became the first physicians to successfully treat a pediatric Degos patient with eculizumab. Shapiro later observed the resolution of Degos skin lesions in an adult patient with an overlap syndrome involving systemic lupus, systemic sclerosis, and Degos disease who was treated with treprostinil for her pulmonary hypertension.
