Diagnosis Physical examination A thorough history and physical examination is often sufficient to diagnose tinea. Microscopy Potassium hydroxide KOH stain a commonly-used method for diagnosing tinea because it is inexpensive, easy to perform, and has high sensitivity.

Some studies have demonstrated improved cure rates with concomitant steroid and antifungal topical applications; however, these results were based on low-quality evidence. The differential diagnosis for tinea cruris includes several other dermatologic conditions affecting the groin with similar presentations. Candidiasis, erythrasma, psoriasis, and seborrheic dermatitis exhibit comparable signs and symptoms and are most commonly confused with the fungal groin infection.

Unlike tinea cruris, candidal intertrigo frequently affects women, and the rash may involve the scrotum and penis in males. The rash of erythrasma lacks an active border and demonstrates coral-red fluorescence on Wood lamp examination. Psoriasis will likely manifest in other areas in addition to the crural region. Seborrheic dermatitis presents with greasy scales on an erythematous base. Patients with tinea cruris who undergo an appropriate treatment course experience cure rates ranging from 80 to 90 percent.

Failure of therapy and recurrence are the most likely complications of tinea cruris. They have been attributed to reinfection from close contacts, autoinfection from separate body locations, infection by uncommon species such as zoonoses, misdiagnosis, drug resistance, and non-adherence to the management plan. Also, chronic application can result in skin atrophy and telangiectasias.

Consultation with dermatology or infectious disease may be warranted in recurrent or recalcitrant cases. Patient education should focus on non-pharmacologic measures to treat and prevent recurrences of tinea cruris. Loose-fitting, non-restrictive garments should be encouraged, and clothing should not be donned until the underlying skin is completely dried.

Tinea cruris is a prevalent pathology with a worldwide distribution and an extensive history of affecting human populations. Despite our familiarity with the condition, there has been limited research specific to this subset of dermatophyte infections. Renewed interest has emerged with the development of recalcitrant infections and concern over fungal resistance. Self-treatment with easy-to-access over-the-counter topical antifungal and steroid preparations have been implicated as a probable cause of the observed decrease in treatment efficacy.

In the context of fungal resistance, newly developed formulations such as luliconazole and underutilized, older agents like ciclopirox may be beneficial. With regard to corticosteroids, there is conflicting data on the appropriateness of their use for tinea cruris.

Current management principles and guidelines label them as mistreatment; however, continued investigations of their utility are underway. If a practitioner believes topical steroids may benefit a patient, close supervision should be maintained throughout the treatment course with continued consideration of known adverse event potential for the individual and public health outcomes.

With an understanding of the changing landscape of this common condition, and by implementing an interprofessional healthcare team approach including primary care clinicians including PAs and NPs , dermatologists, infectious disease specialists, pharmacists, and nursing, patient care and public health may be improved through targeted, conscientious mycological treatment, patient education, and antifungal stewardship.
