Malignant Atrophic Papulosis Presenting with Intestinal Perforation: A Case Report.

Malignant atrophic papulosis sometimes known as Degos' disease is an idiopathic, uncommon condition with fewer than 200 occurrences documented. It is a chronic thrombo-obliterative vasculopathy characterised by papular skin lesions with a core porcelain-white atrophy and a surrounding telangiectatic border. We report a 15-year-old male patient with a recurrent history of hollow viscus perforation, which was managed on all the occasions with exploratory laparotomy and primary perforation repair. Additionally, the patient had a five month history of numerous, non-itchy, atrophic papules with a core porcelain-like area and hyperkeratotic margins, characteristic of Degos' disease. The only basis for diagnosis is the distinctive skin lesions with biopsy. Along with systemic lupus erythematosus and other connective tissue diseases, tuberculosis must also be taken into account while assessing the clinical presentation of malignant atrophic papulosis. There is currently no known treatment for malignant atrophic papulosis that has been effective. Keywords: case reports; intestinal perforation; malignant atrophic papulosis; ulcer; vasculitis.

A fatal case of malignant atrophic papulosis in a pediatric patient.

A 17-year-old Caucasian boy presented with progressive left-sided weakness, transient slurred speech, and skin lesions characterized by 3-5 mm, pink, asymptomatic papules with white atrophic centers on his central abdomen, back, and lower extremities. Skin biopsy confirmed the diagnosis of malignant atrophic papulosis, a rare vasculopathy that leads to the occlusion of small- and medium-sized arteries. He was treated with cyclophosphamide, eculizumab, treprostinil, pentoxifylline, heparin, and acetylsalicylic acid. Despite the aggressive immunosuppression, humanized monoclonal antibodies, and antiplatelet therapy, he died two months after presentation. We report this case to highlight diagnostic features, as well as to highlight the importance of early diagnosis and treatment.

Worsening skin lesions but no diagnosis.

A diagnosis was arrived at by doing something that the patient's other doctors hadn't: perform a biopsy.

Degos disease: A radiological-pathological correlation of the neuroradiological aspects of the disease.

Malignant atrophic papulosis (Degos disease) is an unusual thrombotic microangiopathy of uncertain etiology. The disease characteristically involves the skin and internal organs, with nervous system involvement more common in children. We present a case with diverse neurological manifestations including cranial nerve palsies, gait instability, and urinary incontinence. The patient also developed white papular lesions on her lower extremities and back. Magnetic resonance imaging (MRI) demonstrated progressive intracranial and spinal abnormalities. Despite treatment with numerous biologic agents, the patient had persistent clinical deterioration and expired one month after admission. We highlight the extensive neurologic manifestations of Degos disease correlated with neuroradiological imaging and pathological features. Nervous system involvement in Degos disease requires careful neurologic and dermatologic exam with central nervous system (CNS) magnetic resonance imaging to distinguish it from non-organic etiologies of similar symptoms.

Chronic pleuritis leading to severe pulmonary restriction: a rare complication of Degos disease.

This case demonstrates chronic fibrosing pleuritis, as a rare pulmonary aetiology for mortality in patients with Degos disease or malignant atrophic papulosis (MAP). Knowledge of this unusual complication will help physicians identify this entity early and provide appropriate treatment.Patients with MAP die from gastrointestinal and brain involvement within 2-3 years of diagnosis. This case is unique as the patient survived for 9 years and died secondary to respiratory failure, which had not been reported before. Our patient was a young man, diagnosed with MAP at the age of 17. His skin and gastrointestinal disease were controlled with eculizumab and parenteral treprostinil. The patient developed severe restrictive pulmonary disease, required ventilatory support, and died from respiratory failure. An autopsy revealed chronic fibrosis pleuritis. Longer surviving patients with MAP might suffer from significant respiratory disease. Pulmonary function test should be obtained to identify subclinical respiratory limitation.

Pediatric Malignant Atrophic Papulosis.

Malignant atrophic papulosis (MAP), also known as Degos disease, is an extremely rare disease that is characterized by its unique skin presentation (namely, central, porcelain-white atrophic lesions with a telangiectatic rim). MAP has the following 2 variants: cutaneous MAP is manifested in the skin alone, whereas systemic MAP affects the gastrointestinal tract, central nervous system, lungs, and other internal organs. Some patients who presented with only cutaneous symptoms at first may develop systemic symptoms several years later. Although the exact pathologic mechanisms are unclear, Magro et al suggested in a recent study that MAP is a vascular injury syndrome that involves complement component C5b-9 complex deposition and high expression of interferon-α. The prognosis of systemic MAP is poor and typically fatal within a few years. Nonetheless, because the C5b-9 complex is detected in MAP, some researchers have suggested combined treatment with eculizumab (a humanized monoclonal antibody against C5) and treprostinil (a prostacyclin analog). Here, we report on a girl with systemic MAP who had severe central nervous system involvement and responded to eculizumab.

Malignant atrophic papulosis with motor aphasia and intestinal perforation: A case report and review of published works.

Malignant atrophic papulosis (MAP) is a rare type of obliterating vasculopathy that can present as pure cutaneous lesions or a systemic entity affecting multiple organs. Systemic disease, such as gastrointestinal or central nervous system involvement, may predispose the patients to poorer or even fatal outcomes. We present a 30-year-old female patient with systemic manifestation of MAP 10 days after delivery of a full-term pregnancy who subsequently developed motor aphasia and intestinal perforation. The patient was administrated empirical treatment with an antiplatelet, anticoagulant, methylprednisolone sodium succinate and alprostadil. Antibiotics were administrated due to intestinal perforation and secondary sepsis. Despite all treatment, the patient died a week later. We summarized all the previous reports of MAP based on thorough review of previous published work. Overall, this is the first patient with MAP combined with motor aphasia and intestinal perforation and may provide insights for future studies on the treatment of this disease.

Benign atrophic papulosis (Köhlmeier-Degos disease): the wedge-shaped dermal necrosis can resolve with time.

BACKGROUND: Atrophic papulosis is a rare thrombo-occlusive disease, characterized by the appearance of multiple atrophic porcelain-white skin papules, with a surrounding erythematous rim, which are histologically consisting of wedge-shaped necrosis of the dermis. OBJECTIVE: It consists of two variants: (i) the benign atrophic papulosis (BAP) only involving the skin and (ii) the malignant atrophic papulosis (MAP) also involving several internal organs with a cumulative five-year survival rate of approx. 55%. While the probability of only having a BAP at onset is approximately 70%, increasing to 97% after 7 years of monosymptomatic cutaneous course, no close long-term follow-up of the development of the skin lesions has been reported. METHODS: We present a precise visual documentation of the evolution of the disseminated skin lesions in a female patient with BAP spanning over two decades. RESULTS: A considerable improvement and/or clinical resolution of the majority of the lesions disputing the scarring character of the atrophic porcelain-white skin papules has been detected. CONCLUSION: BAP not only exhibits an excellent prognosis, but resolution of lesions can also occur after a considerable period of time.

Congenital Degos Disease: Case Report and Dermoscopic Findings.

Pediatric Degos disease is rare, with only 36 cases reported in the medical literature. Classically the diagnosis has been established according to pathognomonic histopathologic findings, but when these features are not present, there may be a delay in diagnosis. We report the second congenital case of Degos disease, highlighting the clinical and dermoscopic findings.

KEY TEACHING POINTS.

A case of malignant atrophic papulosis with cranial nerve and peripheral nerve impairment.

Malignant atrophic papulosisis is a rare, multisystem obliterative vasculopathy of unknown etiology, occasionally involving the cranial nerve. We describe the first case of malignant atrophic papulosisis with cranial nerve and peripheral nerve involvement in China. A 47-year-old woman presented to our hospital with atrophic porcelain white papules over the trunk and extremities, numbness in the right calf, vision decrease and impaired movement of the right eye. She was diagnosed with malignant atrophic papulosisis, based on characteristic symptoms and histopathologic examination. The patient was treated with dipyridamole and aspirin for 9 months, but later died of gastrointestinal hemorrhage. We reviewed currently available case reports on cranial nerve involvement in malignant atrophic papulosisis and emphasized the importance of skin biopsy in diagnosing this disease.

The effects of Eculizumab on the pathology of malignant atrophic papulosis.

BACKGROUND: Degos disease is a frequently fatal and incurable occlusive vasculopathy most commonly affecting the skin, gastrointestinal tract and brain. Vascular C5b-9 deposition and a type I interferon (IFN) rich microenvironment are held to be pathogenetically important in the evolution of the vascular changes. We recently discovered the use of eculizumab as a salvage drug in the treatment of near fatal Malignant atrophic papulosis (MAP). The effects of eculizumab on the pathology of MAP are explored. METHODS: Archival skin and gastrointestinal biopsy material was procured over a 2.5-year period before and after eculizumab therapy in our index case. Routine light microscopy and immunohistochemical assessment for C3d, C4d, C5b-9, MxA and caspase 3 were examined. Direct immunofluorescent studies were also conducted on select biopsy material. RESULTS: The patient had received eculizumab as a emergent life saving measure and following rapid improvement he continued with biweekly infusions for 4 years. Although improved he continues to have signs and symptoms of persistent abdominal disease. Pre-Eculizumab biopsies showed an active thrombotic microangiopathy associated with a high type I interferon signature and extensive vascular deposits of C5b-9 in skin and gastrointestinal biopsies. Endothelial cell apoptosis as revealed by Caspase 3 expression was noted. Inflammation comprising lymphocytes and macrophages along with mesenchymal mucin was observed as well. Post-eculizumab biopsies did not show active luminal thrombosis but only chronic sequelae of prior episodes of vascular injury. There was no discernible caspase 3 expression. After 12 months of therapy, C5b-9 was no longer detectable in tissue. The high type I IFN signature and inflammation along with mucin deposition was not altered by the drug. In addition, there was little effect of the drug on the occlusive fibrointimal arteriopathy which appears to be one characterized by extensive myofibroblastic expansion of the intima potentially as revealed by staining for smooth muscle actin without immunoreactivity for desmin and myogenin. CONCLUSIONS: Complement activation and enhanced endothelial cell apoptosis play an important role in the thrombotic complications of MAP. However, the larger vessel proliferative intimal changes appear to be independent of complement activation and may be on the basis of other upstream mechanisms. Monitoring C5b-9 deposition in tissue is likely not of great value in assessing treatment response to eculizumab given the persistence of C5b-9 in tissue for several months despite clinically effective C5 blocking therapy. A more integrated approach addressing upstream and downstream pathways in addition to those attributable to complement activation are critical for the successful treatment of MAP. Eculizumab may be used as salvage therapy in critically ill patients with thrombotic microangiopathy.

Effective treatment of malignant atrophic papulosis (Köhlmeier-Degos disease) with treprostinil--early experience.

BACKGROUND: Malignant atrophic papulosis (Köhlmeier-Degos disease; MAP) is an uncommon endotheliopathy with pathological findings similar to the vascular lesions of systemic sclerosis. These two disorders can overlap. When associated with visceral lesions, MAP has been considered almost universally and rapidly fatal. A recent report described dramatic response to treatment with eculizumab, but disease progression after initial response to therapy has occurred. METHODS: We describe the clinical and pathologic findings in two patients, one with MAP and the other with MAP like lesions, who received treatment with subcutaneous treprostinil. One patient had an overlap syndrome with features of systemic lupus erythematosus (SLE) and scleroderma and severe pulmonary hypertension. She also had very extensive MAP like cutaneous lesions. There was no evidence of central nervous system (CNS) disease and laparoscopy revealed no visible MAP lesions on the serosa of the small bowel. The second patient had experienced life-threatening disease progression despite ongoing eculizumab therapy. During this treatment, he had developed CNS and bladder involvement with neurologic symptoms and gross hematuria. RESULTS: Patient one was placed on therapy with treprostinil for her pulmonary hypertension, but in the months subsequent to initiation of treatment, dramatic and complete resolution of cutaneous MAP like lesions and disabling digital pain occurred. In patient two, therapy with treprostinil was temporally associated with clearing of hematuria, resolution of CNS symptoms and improvement in MRI findings. CONCLUSIONS: Treprostinil may offer a second effective treatment approach to individuals with MAP or "rescue therapy" to those in whom eculizumab treatment has failed to maintain suppression of disease activity.

Malignant atrophic papulosis (Köhlmeier-Degos disease) - a review.

UNLABELLED: DEFINITION OF THE DISEASE: Malignant atrophic papulosis (MAP), described independently by Köhlmeier and Degos et al., is a rare, chronic, thrombo-obliterative vasculopathy characterized by papular skin lesions with central porcelain-white atrophy and surrounding teleangiectatic rim. EPIDEMIOLOGY: Less than 200 cases have been described in the literature. The first manifestation of MAP usually occurs between the 20th and 50th year of life. CLINICAL DESCRIPTION: The cutaneous clinical picture is almost pathognomonic. The histology is not consistent but in most cases it shows a wedge-shaped connective tissue necrosis in the deep corium due to a thrombotic occlusion of the small arteries. In the systemic variant, manifestations mostly occur at the intestine and central nervous system. ETIOLOGY: The etiopathogenesis of the disease remains unknown, a genetic predisposition may occur. Vasculitis, coagulopathy or primary dysfunction of the endothelial cells have been implicated. DIAGNOSTIC METHODS: Diagnosis is only based on the characteristic skin lesions. DIFFERRENTIAL DIAGNOSIS: It depends on the clinical presentation of MAP, but systemic lupus erythematosus and other connective tissue diseases need to be considered. MANAGEMENT: No effective treatment exists for the systemic manifestations, while compounds that facilitate blood perfusion have achieved a partial regression of the skin lesions in single cases. PROGNOSIS: An apparently idiopathic, monosymptomatic, cutaneous, benign variant and a progressive, visceral one with approx. 50% lethality within 2-3 years have been reported. Systemic manifestations can develop years after the occurrence of skin lesions leading to bowel perforation and peritonitis, thrombosis of the cerebral arteries or massive intracerebral hemorrhage, meningitis, encephalitis, radiculopathy, myelitis.

A case of Degos disease successfully treated with corticosteroid combined with cyclophosphamide.

Degos disease is a rare disorder characterized by systemic vasculitis involving various organs. There is no established, effective treatment for the disorder, and its prognosis is still poor. Combination therapy with corticosteroid and cyclophosphamide is considered effective for vasculitides involving the small arteries such as ANCA-associated vasculitis. We present here a 42-year-old man who developed Degos disease over several months, and was successfully treated using combined treatment with corticosteroid and cyclophosphamide.
