Wound, pressure ulcer and burn guidelines - 4: Guidelines for the management of connective tissue disease/vasculitis-associated skin ulcers

The Japanese Dermatological Association prepared guidelines focused on the treatment of skin ulcers associated with connective tissue disease/vasculitis practical in clinical settings of dermatological care. Skin ulcers associated with connective tissue diseases or vasculitis occur on the background of a wide variety of diseases including, typically, systemic sclerosis but also systemic lupus erythematosus (SLE), dermatomyositis, rheumatoid arthritis (RA), various vasculitides and antiphospholipid antibody syndrome (APS). Therefore, in preparing the present guidelines, we considered diagnostic/therapeutic approaches appropriate for each of these disorders to be necessary and developed algorithms and clinical questions for systemic sclerosis, SLE, dermatomyositis, RA, vasculitis and APS.

Cutaneous polyarteritis nodosa localized to a region of lymphedema secondary to Streptococcus viridans cellulitis and multiple surgeries

Cutaneous polyarteritis nodosa (CPAN) is a chronic, indolent, single organ arteritis that generally presents with lower extremity nodules and/or livedo racemosa, accompanied by malaise and arthralgias. CPAN is often triggered by infection, commonly Group A streptococcal species, and is considered an autoimmune reaction. Scarring from surgery and obliterative lymphangiitis from bacterial cellulitis are the causes of lymphedema. Lymphedematous skin is predisposed to autoimmune disorders. Herein we report a 53-year-old woman who developed CPAN restricted to a localized area of the right upper arm-shoulder that had undergone multiple surgeries, complicated by episodes of Streptococcus viridans cellulitis. Clinically, a 15 cm diameter plaque exhibited violaceous, reticulate margins, subtle papules and nodules and central livedo racemosa. Biopsy showed numerous foci of arteritis in active, subacute and reparative stages. In addition, a broad zone of fibrosis replaced the deep dermis-subcutis zone and harbored numerous dilated lymphatic vessels scar lymphedema. Treatment consisted of high potency topical corticosteroids under occlusion; remission after 3 months therapy and follow-up. CPAN primarily affects the lower legs, a region of frequently affected by phlebolymphedema. This report of CPAN localized to an area of scar lymphedema underscores the importance of lymphatic function in the pathogenesis of CPAN.
