Clinician’s Corner: Jock Itch

Tinea cruris (jock itch) is a fungus infection involving the fold between the upper thigh and groin area. Tinea cruris is far more common in men than women. Often, infection results from the spread of the dermatophyte infection from concomitant tinea pedis, moving up the leg. Tinea on the groin looks like scaly, itchy, red spots, usually on the inner sides of the skin folds of the thigh. Patients plagued with sweating, obesity, diabetes, and immunodeficiency are most likely to get jock itch.

Infection may spread to the buttocks. Usually the scrotum in males is usually not involved.

Treatment:

  • Terbinafine (Lamisil cream):
    • For tinea cruris apply once a day for 7 days
  • Clotrimazole (Lotrimin) or Miconazole (Micatin):
    • Apply twice daily for 2 weeks.
    • Any of the OTC or Rx azole antifungals are equally effective

“Tightie whities”  or boxers?? Cotton briefs hold moisture and keep it against the skin, allowing dark, warm moist conditions that the fungus/yeast thrive in.  If you choose briefs, choose moisture-wicking synthetic materials and be sure to shower and put on a fresh pair after working out.  Here is a tip… put on your socks before underwear.
