Degos disease is a rare, chronic, thrombo-obliterative vasculopathy involving small- and medium-sized arteries and affecting multiple organ systems. Neurologic manifestations occur in around 20% of patients, including cerebral hemorrhage, subdural hematoma, thrombosis of cerebral arteries, venous sinus thrombosis, encephalitis, meningitis, polyradiculoneuropathy, cranial neuropathy, and myopathy., However, there have been few reports documenting spinal involvement. We herein present a case of Degos disease with severe ischemic myelopathy.
A 20-year-old female with unremarkable family history and no history of drug abuse presented with multiple papules on both legs since June 2014. The skin lesions were asymptomatic but rapidly proliferated to trunk and upper extremities over a course of one year. In mid-April 2016, she developed sudden onset of weakness and sensory disturbance in the right leg with dysuria and dyschesia. Since then, the symptoms lasted without any deterioration.
About 5 months later, the patient suddenly developed significant lower back pain, which rapidly progressed to an acute worsening of sensory and motor function disturbances in both lower extremities. On spinal magnetic resonance imaging (MRI), T2-weighted high-intensity signals at the level of medullary cone (T12-L1) were confirmed. Yet, the patient was pregnant for 6 months. She refused further treatment and was discharged home. One week later, she had a similar episode of lower back pain, followed by a complete loss of sensory and motor function of legs as well as bladder and intestinal continence. On admission, physical examination revealed multiple asymptomatic white to pink papules (5–10 mm in diameter with a central, porcelain-white atrophic center surrounded by an erythematous rim) on the trunk and proximal extremities [Figure 1]a and [Figure 1]b, which spared the scalp, genitals, and palmoplantar regions. Neurological examination showed paralysis and sensory disturbance below T4. On serological examinations, the coagulation test demonstrated abnormal fibrinogen (4.26 g/l) and D-Dimer levels (1.41 mg/l). Besides, increased platelet account (730*109/l) was noted. Venereal disease research laboratory test and the fluorescent treponemal antibody absorption test were negative. In cerebrospinal fluid, lymphocyte count was 16/μl, and there was a markedly raised protein level (2.69 g/l). Oligoclonal bands and NMO-IgG were negative. On neuroimaging exams, spinal MRI revealed T2-weighted high-intensity signals between T3 and T4, T6 and T8, as well as T12 and L1 [Figure 2]a, [Figure 2]b, [Figure 2]c. However, gadolinium enhancement was not observed on these lesions as expected. Only MRI of cauda equine showed mild enhanced T1-weighted signals after intravenous meglumine gadopentetate infusion [Figure 2]d. Meanwhile, we noticed the skin eruptions and carried out a biopsy of lesions, which showed epidermal atrophy, wedge-shaped dermoepidermal necrosis, arteriolar obliteration in the corium and perivascular lymphomonocitic infiltration [Figure 1]c, [Figure 1]d, [Figure 1]e, [Figure 1]f. These findings led to the diagnosis of Degos disease, and her central nervous system (CNS) manifestations were considered as a result of this rare disease. She was subsequently prescribed anticoagulated and antiplatelet therapy. Her condition stayed stable. Until now, she has no further deterioration.

Histopathology of the skin biopsies, visualized by hematoxylin and eosin staining (c-f). Epidermal atrophy, hyperkeratosis, and wedge-shaped dermoepidermal necrosis were visible (×40, ×100) (c and d); the panels demonstrated occlusion of blood vessels in the corium and perivascular lymphocytic infiltration (×100, ×200) (e and f)|

Degos disease is a rare and life-threatening disease, especially when associated with gastrointestinal tract or CNS. It is characterized by papular skin lesions with central porcelain-white atrophy and surrounding telangiectatic rim. The cutaneous clinical picture is almost pathognomonic. The histology in most cases shows a wedge-shaped connective tissue necrosis in the corium due to a thrombotic occlusion of the small arteries. Systemic symptoms may develop suddenly, either occurring simultaneously or subsequently, even before skin manifestations. In our case, systemic manifestations developed 2 years after the occurrence of skin lesions leading to ischemic myelopathy. Myelitis was first suspected. However, the patient did not respond to steroid treatment. Moreover, increased circulating levels of fibrinogen and platelet account were noticed, and on MRI, patchy lesions from periphery to center of the spinal cord, a characteristic of Degos disease was noted, indicating ischemic changes of spinal cord related to a possible disseminated occlusive vasculopathy. To the best of our knowledge, only two cases of Degos disease involving spinal cord damage were reported. Occlusive vasculopathy and diffuse myelomalacia or ischemic myelopathy were discovered at autopsy.,
In conclusion, the features of our case highlight the importance of considering Degos disease in case of spinal vasculopathy especially when there is skin involvement. Skin biopsy is essential for the diagnosis of this entity. Platelet antiaggregants as well as anticoagulants seemed effective to the control of the disease.
