Acta Derm Venereol (Stockh) 29:369-87 Introduction ● Very rare disease (130-150 publications with approx. 200 cases) ● No age or racial prevalence ● The skin lesions are pathognomonic ● The etiology is unclear ● No known effective therapy Classification ● Vasculopathy / endovasculitis ● Occlusive arteriopathy ● Progressive, small- and mediumsize arterial occluding disease ● Leads to tissue infarction ● It initially involves the skin (systemic lesions may rarely precede skin lesions) Systemic involvement Gastrointestinal tract: abdominal pain, nausea, vomiting, diarrhoea or constipation and, in the later stages, intestinal perforation and haemorrhage Systemic involvement Neurological involvement: peripheral and central nervous system headache, dizziness, seizures, hemiplegia (total or partial paralysis of one side of the body), aphasia (loss or impairment of the power to use or comprehend words), paraplegia (paralysis of the lower half of the body), gaze palsy (partial or complete inability to move the eyes to all directions of gaze) Systemic involvement Other organs Cardiac: Pleuritis, Pericarditis Eye: eyelid ptosis (drooping of the upper eyelid), optic neuritis (inflammation of optic nerves), diplopia (double vision), visual field defects Lungs, kidneys, bladder, liver, pancreas High WA et al (2004) Is Degos' disease a clinical and histological end point rather than a specific disease? J Am Acad Dermatol 50:895-9 Ball E et al (2003) Degos' disease: a distinctive pattern of disease, chiefly of lupus erythematosus, and not a specific disease per se. Am J Dermatopathol 25:308-20 Etiology / Pathophysiology ● Unknown ● No circulating immune complexes, antiendothelial cell antibodies, anticardiolipin antibodies (in sime cases antiphospholipid antibodies detected) ● No medication and toxic chemicals Etiology / Pathophysiology ● Disturbance of immunity ● Viral infection (no paromyxovirus) ● Abnormality of the blood clothing system ● Primary endothelial cell defect Etiology / Pathophysiology ● Primary endothelial cell defect with secondary thrombosis (?) ● Partially impaired fibrinolytic activity and alterations in platelet function ● No inflammation ! Etiology / Pathophysiology ● Familial cases: Autosomal dominant mode of inheritance (?) ● Are familial cases more benign than sporadic ones ? 32 cases in 10 families: 4 cases with malignant course (12.5%) ! Pinault AL et al (2004) Ann Dermatol Venereol 131:989-93 Differential diagnosis ● Lichen myxedematosus ● Allergic vasculitis ● Systemic Lupus erythematosus with scar formation ● Papulonecrotic tuberculoid Course and prognosis ● Malignant (systemic involvement) ● Benign (cutaneous involvement only) Mensing C, Mensing H (2002) Degos atrophic malignant papulosis.
