Increased aggressive-growth basal cell carcinoma in the VA population of Palo Alto, California.

We have noted a high frequency of aggressive-growth basal cell carcinomas (BCCS) in our patient population. Subtypes observed with increased frequency include morpheaform, infiltrative, and micronodular.
Our purpose was to examine the frequency of histologic subtypes of all BCCs seen in the dermatology clinics in the Veterans Affairs Palo Alto Health Care System in an 18-month period.
We reviewed 432 consecutive primary BCC biopsy specimens taken from 252 patients.
Aggressive-growth BCC was observed in 20.7% of biopsy specimens, including 13.4% morpheaform, 5.7% infiltrative, and 1.6% micronodular subtypes. The mean age of the patient population was 70 years, with a standard deviation of 9.1 years.
Our observed percentage of aggressive-growth BCC is substantially higher than in most other large studies. A high frequency of aggressive-growth BCC coupled with the increasing incidence of nonmelanoma skin cancer may have significant implications for future health care resource allocation.
