Brooke’s Blog: Dermatology Questions and Answers

Dear Brooke, For the past few weeks, I’ve been experiencing itchiness and redness in my groin area, especially after I work out at the gym. I tried using Gold Bond powder, but it hasn’t really helped at all.  What can I do to get rid of this quickly? Thanks! – Dave, 30, from Brooklyn Dear Dave, It sounds like you are describing a condition called tinea cruris, more commonly known as “jock itch.” Tinea cruris is caused by a dermatophyte (fungus) and can be contagious and easily transmitted through contaminated sheets, towels, or caused by wearing tight-fitting clothing or wet clothing that comes in close contact with the groin region. This condition is more common in men and women and generally affects adults more so than children. Symptoms of tinea cruris include a rash in the groin region that can be very itchy. Often times, tinea cruris can be triggered by a tropical climate, exercise, competitive sports, or from obesity. Treatment of tinea cruris includes the application of a topical antifungal cream such as ketoconazole to the affected area, usually twice a day for a few weeks until the symptoms resolve. For patients who have chronic tinea cruris, an oral antifungal medication can be used to treat the condition in conjunction with the topical antifungal cream. It is important for patients affected by tinea cruris to prevent reinfection, because it is very common to have a recurrence of the symptoms. We advise patients to completely dry their groin area after bathing and to use separate towels for that area to avoid contaminating other areas of the body. Additionally, it is recommended for patients with tinea cruris to avoid wearing tight-fitting clothing to prevent the accumulation of moisture to the groin region. Patients that are overweight or obese are instructed to lose weight to reduce the incidence of tinea cruris that can be caused due to friction. Rest assured that the prognosis of tinea cruris is very good; most patients are symptom free after undergoing topical antifungal therapy after a few weeks. Best Regards, Brooke Studley, RPA-C
