  • Title: Cutaneous vasculitis in adult polymyositis/dermatomyositis.
    Author: Feldman D, Hochberg MC, Zizic TM, Stevens MB.
    Journal: J Rheumatol; 1983 Feb; 10(1):85-9. PubMed ID: 6842491.
    Abstract:
    Seven (9.2%) of 76 patients with adult-onset polymyositis/dermatomyositis (PM/DM) seen over an 11-year period had cutaneous vasculitis. This was manifest by dermal and/or subcutaneous nodules in 4, periungual infarcts in 3 and digital ulceration in 2. When these 7 patients were compared to the remaining 69, a significant association was noted between cutaneous vasculitis and DM (p = .025); only 1 of 31 patients with primary PM and none of 18 with overlap syndromes had vasculitis. Furthermore, 2 (28.6%) of those with vasculitis had an associated malignancy compared to only 4 (5.8%) of those without vasculitis. These data document the occurrence of cutaneous vasculitis in adult-onset PM/DM and suggest that its presence may be a marker of an underlying malignancy.
