Are there any differences between body ringworm and groin ringworm?

Tinea corporis and tinea cruris have clear medical distinctions, mainly体现在 the following aspects: 1. **Affected Areas**: Tinea corporis typically occurs on smooth skin areas such as the trunk, proximal limbs, and may also appear on the face; whereas tinea cruris specifically refers to fungal infections occurring on the inner side of the groin (the perineal and perianal skin), representing a special type of tinea corporis affecting the genital and groin region. 2. **Symptoms**: Tinea corporis commonly presents as red patches covered with fine scales, usually the size of a coin or copper coin, with relatively mild itching; tinea cruris may present as annular or semi-annular patches accompanied by papules, vesicles, and more intense itching. Patients often scratch repeatedly, which may lead to extensive erythema. 3. **Infection Sources**: Tinea corporis is more common in urban areas and is often transmitted by keeping pets (e.g., cats, dogs); tinea cruris mainly spreads from patients with tinea manuum/pedis or onychomycosis through poor hygiene practices—such as touching towels or clothing contaminated by these infected areas and subsequently touching the groin area.
