Basal Cell Carcinoma Treated with Mohs Surgery: A Comparison of 54 Younger Patients with 1050 Older Patients

Abstract

The average age of patients with basal cell carcinoma (BCC) is over 60 years, and fewer than 5% of patients with this tumor are under 30 years of age. A comparison of younger (15 to 30 years) and older (56 to 70 years) patients with BCC was conducted to identify specific tumor or host features associated with BCC occurring early in life. According to data collected over an 11-year period, 54 of 2728 (2%) BCCs occurred "de novo" in younger patients. In contrast to the predominantly male older group, most of the younger patients were female. An increased use of tanning booths and hair-dyes was associated with the younger patients (P less than .001). More overall sunlight exposure and actinic keratoses were associated with the older patients (P less than .01). Defect and lesion sizes were smaller (P less than .01) in the younger group. Location, histology, and clinical morphology did not differ appreciably between the two groups. De novo BCCs in younger and older patients are similar, although some differences do exist.
