Eighty-nine cases of lupus erythematosus under observation in the outpatient department of the Winnipeg General Hospital have been investigated. Of this number, six were instances of the acute disseminate type and are not considered in this paper.
A study of the incidence according to sex showed 60 per cent of patients to be female.
A tabulation according to age showed the disease to have a marked predilection for the third and the fourth decade, approximately two thirds of the patients falling into that age group (fig. 1). There was no patient under 10 years of age. Some of the older patients had had the disease in mild form for many years but did not seek treatment.
A study of the seasonal incidence was particularly interesting. Figure 2 shows the month of onset in forty-seven cases.
