“…There is wide divergence in the estimates of the incidence of malignant disease; Curtis et al (1952) found eight neoplasms, including reticuloses, in 45 patients with dermatomyositis, but in other series the reported prevalence of neoplasms has varied from 500% in patients over 40 (Arundell et at., 1960) to 6.7% in 270 patients seen at the Mayo Clinic (Christianson et al, 1956). Williams (1959), in a review of the literature, pointed out the possibility of error because cases with an association between dermatomyositis and neoplasm were more likely to be published.…”
