Degos' disease (DD) also known as malignant atrophic papulosis is considered to be a disorder of abnormal coagulation with obliterative arteritis. Its association has been described with connective tissue disorders, human immunodeficiency virus infection (HIV) and wegener's granulomatosis. Gastrointestinal, neurological, ocular, cardiovascular, and pulmonary involvement can also occur in DD. Benign version of DD with only cutaneous manifestations has been described. We are presenting a case of 7-year-old female with multiple irregular-shaped crusted tender lesions with porcelain white scars of healed lesions mainly over the trunk and upper limb and few lesions involving face and legs for the last 6 months. There was a history of occasional headache. Other systemic examination by experts was within normal limit. On further investigation, antinuclear antibody, and anti-Scl-70 antibody were positive with histopathology suggestive of DD. The patient had reduced peak expiratory flaw rate (PEFR). The patient was given oral prednisolone without much improvement. With oral aspirin for a month, the patient had mild improvement. The patient is presently under follow-up for future systemic involvement and response to therapy. Anticipated mortality in DD is 50%–60%. Earlier diagnosis and proper management at such a younger age might benefit the patient; however, they need to be followed up for complications. DD is very rare and very few cases have been reported in children. Ours is unique with anti-Scl-70 antibody positivity.

| Introduction|| |
Degos' disease (DD) also known as malignant atrophic papulosis is a vasculopathy affecting small- and medium-sized arteries due to unknown etiology. Proposed mechanisms for pathogenesis are abnormal coagulation, hyperthrombotic stage, abnormality in endothelial cells and complement-mediated injury leading to obliterative arteritis. Its association has been described with systemic lupus erythematosus, systemic sclerosis, and rheumatoid arthritis, dermatomyositis, human immunodeficiency virus infection (HIV), and Wegener's granulomatosis., It mainly affects age group of 20–40 years with male predominance with ratio of 2–3:1. Some familial cases have been reported. Clinically, it starts as pale-rose round edematous papules sometimes preceded by slight burning affecting trunk and limbs with sparing of face, palms, and soles with 30–40 active lesions at a time. This eventually progresses to ulceration followed by porcelain white scaring with peripheral livid red and telangiectatic rim. Gastrointestinal, neurological, ocular, cardiovascular, and pulmonary involvement can also occur in DD, but usually, skin manifestations precede systemic involvement. Benign version of DD with only cutaneous manifestations has been described.
Drugs such as aspirin, antiplatelet drugs, and fibrinolytics, pentoxifylline, phenylbutazone, heparin, warfarin, dextrans, chloroquine, intravenous immunoglobulin, eculizumab, nicotine patches, treprostinil, and fibrinolytics are claimed to be effective in disease.
| Case Report|| |
A 7-year-old female child presented to us with complaints of the skin ulcers involving mainly upper limb for the last six months. On examination, there were multiple bizarre-shaped crusted tender ulcers without surrounding erythematous rim with porcelain-white scars of healed lesions mainly over the upper limb with few over face [Figure 1] and lower limb and back with sparing of palms and soles. There were few mildly erythematous to skin-colored papules of irregular shape were present over the abdomen [Figure 1]. There was a history of occasional headache. Other systemic examination by experts was within normal limit. Patient had low Hb (11.7 gm/dl), raised total leukocyte count (19,500/cmm), and raised platelet count (6,23,000/cmm). On further investigation, antinuclear antibody (ANA) by enzyme-linked immunosorbent assay (ELISA) was 6.87 with positive index being >1.5 in our institute. ANA profile by immunoblot showed positivity for anti-Scl-70 antibody with titer being 74 U/mL with cutoff being >12 U/mL to be labeled as positive, but the patient did not have any cutaneous manifestations of scleroderma as well as Reynaud's phenomenon. Titer of anti-Scl-70 antibody was not repeated because of nonaffordability of our patient. The patient had reduced peak expiratory flaw rate. Patient being child and from rural area was unable to perform whole pulmonary function test.

Bleeding time, clotting time, prothrombin time, activated partial thromboplastin time, plasma fibrinogen, creatine phosphokinase total, rheumatoid factor, C-reactive protein, cytoplasmic anti-neutrophil cytoplasmic antibody, perinuclear antineutrophilic cytoplasmic antibody, and anticardiolipin antibodies were within normal limits. HIV and serological test (rapid plasma regain) for syphilis were negative. Systemic involvement was ruled out by relevant investigations such as computed tomography scan of the brain and upper gastrointestinal scopy, split lamp examination, and fundoscopy for ocular involvement and echocardiography for cardiac involvement.
A biopsy was taken from both popular lesions over the abdomen and ulcerated lesion over the right arm. Histopathology from popular lesion showed orthokeratotic hyperkeratosis, mild epidermal atrophy, and predominantly lymphocytic infiltrate in papillary dermis and in superficial perivascular area [Figure 2]. Biopsy from an ulcerated lesion histopathologically showed mild orthokeratotic hyperkeratosis, epidermal atrophy, wedge-shaped pale hyalinized area of dermal necrosis, thrombosed capillaries with perivascular hyalinization with mild lymphocytic infiltrate [Figure 3].

The patient was given oral prednisolone 20 mg for 15 days without much improvement. With oral aspirin, 75 mg/day for a month patient had mild improvement. The patient is presently under follow-up for future systemic involvement and response to therapy.
| Discussion|| |
DD mainly affects the age group of 20–40 years. It has been reported in children though only few cases have been described. Very few cases of DD have been reported from India.,,,
Many cases have been described in association with systemic lupus erythematosus (SLE), or DD has been claimed to be a manifestation in spectrum of SLE, but very few cases have been reported in association with SS. To the best of our knowledge, it has not been described in a child with anti-Scl-70 positivity. Hence, our case has unique association with anti-Scl-70 antibody positivity, and patient needs to be under further surveillance for the development of systemic scleroderma as well as for systemic involvement associated with DD. This may be association by chance but, the titer of anti-Scl antibody was quite high from cutoff margin, so we need to follow-up for further conclusion on its association with scleroderma. The patient does not fulfilled the Systemic Lupus Collaborating Clinics or the American College of Rheumatology criteria to be diagnosed as SLE, and no other antibodies were positive in ANA profile to comment on its association with SLE in this particular patient though ANA by ELISA was positive.
Increased C5b-9 deposition has been described in both DD and in scleroderma. This may be the cause of small vessel obliterative vasculopathy – a shared feature in both diseases. Eculizumab – an antibody against C5 which has been found to decrease deposition of C5b-9- has been found to be effective in DD. Treprostinil – a synthetic analog of prostacyclin used in pulmonary hypertension (which may be a feature of scleroderma) has also been found effective in the treatment of DD. Hence, further research is needed to establish correlation between DD and systemic scleroderma and therapeutic guidelines for the two diseases.
Telangiectatic rim surrounding porcelain white scars or ulcers was absent in our patient. May be it was not appreciable because of patient's dark complexion. However, histopathology was very characteristic from both types of lesions. Hence, even in the absence of telangiectatic rim, one should keep DD in the differential diagnosis in the presence of other typical clinical features.
