It is a widely accepted clinical observation that patients with basal cell epithelioma (BCE) seek treatment more often during the summer months. A total of 1,131 consecutive biopsy-proven cases of BCE examined histologically in Louisville, during the years 1970 and 1971, were studied. An analysis proved that there was a statistically significant increase in BCE incidence during the months of July through September for both years. There was no seasonal change in the proportion of exposed to unexposed sites or in the male/female ratio.
