SAN DIEGO – Think beyond the foot: Fungal infections are just the beginning when it comes to skin disorders in athletes, which include ringworm in wrestlers, “jogger’s nipple” in runners, and more serious conditions – like skin cancer.
“from weekend warriors to professional athletes,” said Brian B. Adams, MD, MPH, professor and chair of the department of dermatology at the University of Cincinnati.
In an interview, he discussed specific risks for athletes, the scarcity of data on skin cancer in athletes, and the hazards posed by cotton clothing.
Skin cancer: Risk seems clear, but data are sparse
“Athletes in general appear to be at increased risk in the long term for skin cancer” since they often play and practice during the hours between 10 a.m. and 4 p.m., when the danger of sun exposure is at its highest, he said. In addition, “sweating removes the sunscreen that athletes put on, and there is evidence that sweating actually increases the chance of burning,” he said.
Skiers and snowboarders face unique sun exposure risks, he added. “Snow reflects up to 100% of UV, so even though they may be in shade, they experience UV. And mountain athletes experience greater amounts of UV as the altitude of the mountain increases: At higher altitudes, the atmosphere has less chance of filtering out the damaging rays.”
While it’s obvious that many athletes face extra sun exposure, Dr. Adams pointed out, “very little is definitively known about the actual degree of risk of athletic activities.”
Still, the research that does exist provides plenty of hints about risk. “Large epidemiological studies showed that recreational activities such as sun exposure on the beach or during water sports were associated with an increased risk of basal cell carcinoma, whereas skiing has been shown to be at increased risk for squamous cell carcinoma,” according to a 2008 report on outdoor sports and skin cancer (Clin Dermatol. 2008 Jan-Feb;26[1]:12-5).
“Risk factors of cutaneous melanoma, such as the number of melanocytic nevi and solar lentigines, have been found to be more frequent in subjects practicing endurance outdoor sports. An increased risk for cutaneous melanoma may be assumed for these athletes,” Dr. Adams commented.
Another study, this one published in 2006, found more atypical melanocytic nevi, solar lentigines, and lesions suggestive of nonmelanoma skin cancer in marathon runners, compared with a control group, and the risk was associated with the level of training intensity. The control subjects were more sensitive to the sun and had more common melanocytic nevi (Arch Dermatol. 2006 Nov;142[11]:1471-4).
Counseling about sunscreen may actually work
One strategy to reduce sun exposure is to advise athletes to avoid peak sun hours. However, “the key to caring for the athletes is not only recognizing that their sport may play a role in their disease but also realizing that your therapeutic approach must be tailored to minimize disruption to their practices and competitions,” Dr. Adams said.
However, there’s good news for dermatologists who are willing to push: The study also reported that athletes who were encouraged to use sunscreen were significantly more likely to use sunscreen (P less than .0001).
Watch for other conditions, from jogger’s nipple to ringworm
Dr. Adams offered advice about detection, treatment, and prevention of other skin disorders that affect athletes:
- “Jogger’s nipples” and other kinds of chafing. He has learned to recognize the “red eleven” – two vertical streaks of blood on a runner’s shirt – that represent a case of “jogger’s nipples” caused by chafing. Antibacterial ointment or petroleum jelly are useful treatments, he said, and an application of plenty of petroleum jelly on the nipples prior to a run can be helpful. Cotton shirts should be avoided, he said, in favor of synthetic, moisture-wicking shirts and bras. Chafing can also occur in the underarms and inner thighs, he said, and the same treatments and preventive techniques are useful.
- Callused and bleeding “jogger’s toes.” This can strike runners, especially on the second toe, which is often the longest and most likely to strike the toe box of a shoe. Specialty shoes can help prevent this condition, he said.
- Tinea corporis (ringworm) and herpes gladiatorum. In wrestlers, ringworm is known as tinea corporis gladiatorum because the intensity of skin-to-skin contact in wrestling makes the condition especially common in these athletes. Lesions don’t develop as rings at first; instead, they first appear as relatively nonspecific red round lesions and are most likely to be found in the head, neck, and upper extremities, Dr. Adams noted. Herpes gladiatorum is caused by herpes simplex virus 1; it is also seen in wrestlers and caused by skin-to-skin contact. Topical and oral antifungals clear ringworm, while oral antiviral agents are appropriate for herpes gladiatorum, Dr. Adams said. While herpes gladiatorum clears up and is no longer contagious after 4-5 days, he said, it’s not clear how long wrestlers with ringworm should be disqualified from playing.
