RESUMO
A clinical and epidemiological study of psoriasis in Sri-Lanka is presented. The prevalence in the population is estimated to be over 0.4%. The clinic incidence was 8.7%; of these 53.2% were male, and 46.8% female and 8.3% reported a family history of the disease. The mean age at onset was 25.2 years. The frequency distribution for the age at onset was bimodal with peaks at the second and fifth decades. The age at onset was significantly low in females, in patients with a family history of the disease, in those affected by weather changes and in patients whose disease was precipitated by sore throats. The existence of natural subpopulations of patients is suggested. Clinical types and complications of the disease were not essentially different from those observed in the West.

Eighteen cases of Sweet's syndrome are described. This is the largest series so far reported and the first from the tropics. The essential features are the characteristic morphology, the histological appearances, the dramatic response to corticosteroids and the absence of scarring. Attention is drawn to the frequent involvement of the eyes and joints during the course of the illness. Fever and neutrophilia were found less frequently than a raised ESR or a preceding upper respiratory tract or skin infection. The term Sweet's syndrome is preferred to acute febrile neutrophilic dermatosis. The frequency of occurrence of different clinical manifestations is discussed.
