To the Editor.—
Solar elastosis has been claimed as the primary event in rosacea.1-3 The sequence has been described as dermal edema disorganization, inflammation, and secondary infection.Solar elastosis is a very common accompaniment and precursor of basal cell carcinoma and squamous cell carcinoma on exposed surfaces. Does skin cancer therefore occur frequently in rosacea? To my knowledge, this has not been previously explored in the literature.
Patients and Methods.—
A group of 140 patients (46 men [mean age, 51 years], 94 women [mean age, 42 years]) with rosacea was examined for basal cell carcinoma, squamous cell carcinoma (past or present), solar keratoses, atrophy, purpura, angular scars, solar melanosis, and cutis rhomboidalis nuchae. A control group (drawn from patients attending the emergency ward) matched for age, sex, skin type, and occupation was similarly assessed.The ages ranged from 18 to 84 years, and skin types were defined as follows:
