Tinea Cruris

Tinea cruris is superficial dermatophyte infection affecting groin folds, inner thighs or buttocks. A scaly advancing edge and relative scrotal sparing can help distinguish it from some other groin rashes.

Key takeaways

  • Yeast intertrigo, contact dermatitis, erythrasma and psoriasis can mimic jock itch and do not share the same treatment.
  • Athlete’s foot or infected nails can repeatedly transfer fungus to the groin and should be considered when rash recurs.
  • Topical antifungals may treat limited disease; steroid combinations can mask infection and damage fold skin.

Catalogue matches do not confirm tinea cruris or indicate a safe groin treatment.

What helps distinguish groin rashes?

Tinea often has a defined scaly border spreading onto the thigh. Yeast may involve the scrotum and produce satellite spots, while irritant rash follows friction and moisture. Examination or scraping can clarify persistent cases.

How is recurrence reduced?

Terbinafine has topical and selected oral roles depending on product and diagnosis. Drying folds, changing damp clothing and treating confirmed foot infection may help. Oral treatment requires review of liver health and interactions.

When to seek urgent care

Seek prompt care for severe pain, rapidly spreading redness, fever, pus, blisters, genital ulceration, immune suppression or a severe treatment reaction.
