Epidemiology

Cherry angiomas are the most common cutaneous vascular proliferation, which increase in frequency and size with age. Actinic keratosis is commonly seen in individuals with fair skin and is associated with increasing age and cumulative UV exposure. Seborrheic keratoses are one of the most common skin tumours, typically seen in adults over the age of 30. The incidence of keratoacanthomas is around 1 in 1000 in the UK. The peak incidence is in those over the age of 60. Lipomas can be seen in any age group, but are more common in those between 40-60 years of age. Incidence is similar to keratoacanthomas at 1 in 1000 people. The mean age for pyogenic granulomas is 5–8-year-olds; from then on, the incidence decreases with increasing age. A slight increase in incidence is seen in women.
