ANSWER
The correct answer is dermatoheliosis (choice “d”), also correctly termed photoaging. This condition manifests as a number of specific skin changes, including the items named (choices “a,” “b,” and “c”)—all of which were present on this patient.
DISCUSSION
The consequences of chronic overexposure to UV radiation constitute the most common reason patients present to dermatology practices in the United States. The bulk of this damage takes decades to appear, by which time patients have forgotten about their earlier sun exposure (in fact, they often deny any exposure) and even the painful sunburns that taught them to avoid the sun in the first place.
In general, the effects of sunburns sustained in childhood or young adulthood do not usually manifest until the patient is in his/her 50s or 60s, although patients who are less sun-tolerant (our definition of “fair”) may show signs of damage considerably earlier.
However, with the popularity of artificial tanning among teenagers (and even preteens in some cases), evidence of sun damage is being seen at younger ages than ever. Basal cell carcinomas, once unheard of in teenagers, are being found with increasing frequency in this age-group. In patients ages 12 to 15, there has been a 100-fold increase in the incidence of melanoma—theorized to be due, in part, to the effects of artificial tanning.
This particular patient is typical of cases in which sun damage was obtained more passively. At one time in the US, having a tan was decidedly unfashionable; it marked one as a member of “the lower classes.” But that all began to change after WWI: Hemlines and hairlines rose, Prohibition created a new generation of drinkers and scofflaws, clothing began to be more revealing, and suddenly it was fashionable for women to shave their legs and get a tan.
About that same time, many men began to ignore the long-held tradition of wearing hats and long sleeves when outside, inevitably tanned, and thus gained approval from the opposite sex. Most went off to war in the 1940s, many to the Pacific theater, where they had even more exposure to the sun.
Following WWII, a great number of these men returned to their jobs as farmers, ranchers, or construction workers. Golfing became the “in” sport during leisure time. It’s this generation we’re seeing now for sun-related pathology. Even if they had been inclined to use it, effective sunscreen was not generally available until the early 1970s.
The patient depicted here has a typical collection of the pre-cancerous sun damage known as dermatoheliosis: solar elastosis, actinic keratoses, telangiectasias, and solar atrophy (which affects the arms more than the face). The latter, along with the effects of wind, heat, cold, smoking, and drinking alcohol, constitute the main causes of extrinsic aging.
TREATMENT
Short of heroic efforts, not much will be done for this patient’s dermatoheliosis. However, he was strongly advised to return to dermatology twice a year to watch for the arrival of the basal cell and squamous cell carcinomas that are almost certainly headed his way.
