Tinea Cruris Information

Tinea cruris may form ring-like patterns on the buttocks. Tinea cruris can be very itchy. Tinea cruris is a condition which is contagious and it is a infection transmitted by fomites, such as contaminated towels or hotel bedroom sheets, or by autoinoculation from a reservoir on the hands or feet (tinea manuum, tinea pedis, tinea unguium). Tinea cruris manifests as a symmetric erythematous rash in the groin. Tinea cruris is an infection of the groin area with mold-like fungi called dermatophytes. Tinea cruris (also called ringworm of the groin) is a skin disorder that occurs almost exclusively in adult men. It can sometimes accompany athlete's foot ( tinea pedis ) and other tinea infections.

The condition is more common in men than in women. The fungi love warm, moist places, and they are often a problem for people with active lifestyles, or those who do not look after their personal hygiene carefully enough. Tinea cruris is not contagious; direct person to person contact rarely leads to spreading of tinea cruris.

Tinea Cruris Cause

Tinea cruris is caused by a fungus. Here are the list of some Tinea Cruris causes:

lichen simplex chronicus
eczema
pubic lice
chemical irritation

Tinea Cruris Symptom

Itching may be severe, or the rash may be asymptomatic. The lesions have sharp margins, cleared centers, and active, spreading scaly peripheries. Follicular pustules are sometimes encountered. The area may be hyperpigmented on resolution.

Here are the list of Tinea Cruris Symptom

Itching in groin, thigh skin folds, or anus.
Red, raised, scaly patches that may blister and ooze. The patches often have sharply-defined edges.
Abnormally dark or light skin.

Tinea Cruris Treatment

Drying powder (eg, miconazole nitrate [Zeasorb-AF]) should be dusted into the involved area in patients with excessive perspiration or occlusion of skin due to obesity. Underwear should be loose-fitting. Tinea Cruris Treatment include

Keep the skin clean and dry.
Don't wear clothing that rubs and irritates the area.
Apply topical over-the-counter antifungal or drying powders, such as those that contain miconazole, clotrimazole, or tolnaftate.
Recommend weight loss for patients who are obese and have tinea cruris.
Treat the feet if tinea pedis is present.
Dry the groin carefully after bathing using a separate towel.
Do not share towels, sheets or personal clothing.
Avoid wearing occlusive or synthetic clothing.
If you are overweight, try to lose weight to reduce chafing and sweating.
Keep the groin area clean and dry.
Don't wear clothing that rubs and irritates the area. Avoid tight-fitting and rough-textured clothing.
Wear loose-fitting underwear.
Wash athletic supporters frequently.
After bathing, apply antifungal or drying powders if you are susceptible to jock itch.

Any of the preparations listed in the section on tinea corporis may be used. There is great variation in expense, with miconazole, clotrimazole, butenafine, and terbinafine available OTC and usually at a lower price. Terbinafine cream is curative in over 80% of cases after once-daily use for 7 days.

Differential Diagnosis of Tinea cruris

Tinea cruris must be distinguished from other lesions involving the intertriginous areas, such as candidiasis, seborrheic dermatitis, intertrigo, psoriasis of body folds ("inverse psoriasis"), erythrasma, and rarely tinea versicolor. Candidiasis is generally bright red and marked by satellite papules and pustules outside of the main border of the lesion (see photograph). Candida typically involves the scrotum. Tinea versicolor can be diagnosed by the KOH preparation. Seborrheic dermatitis also often involves the face, sternum, and axillae. Intertrigo tends to be more red, less scaly, and present in obese individuals in moist body folds with less extension onto the thigh. Inverse psoriasis is characterized by distinct plaques. Other areas of typical psoriatic involvement should be checked, and the KOH examination will be negative. Erythrasma is best diagnosed with Wood's light—a brilliant coral-red fluorescence is seen.

Essentials of Diagnosis

Marked itching in intertriginous areas, usually sparing the scrotum.
Peripherally spreading, sharply demarcated, centrally clearing erythematous lesions.
May have associated tinea infection of feet or toenails.
Laboratory examination with microscope or culture confirms diagnosis.
