Patients may report itching and burning in the groin, perineum, or buttocks, with symptoms worsening with heat or sweat (pruritic, erythematous lesions). Many describe exacerbation after wearing tight or synthetic clothing. Risk factors may include previous fungal infections (e.g., tinea pedis), obesity, or diabetes, and environmental factors like high humidity.
What will it look like? (Examination)
In Black skin, Tinea Cruris may present as darker patches (hyperpigmentation) with a red, raised border (erythematous), often in a ring shape with central clearing (annular configuration). Chronic cases may show lichenification, with thickened skin and peripheral scaling.
How can you help? (Treatment)
Topical antifungals like terbinafine or clotrimazole should be applied twice daily for 2–4 weeks, with treatment extending 1–2 weeks beyond symptom resolution. Oral antifungals are used in extensive or refractory cases, typically for 2–4 weeks depending on severity. Recommend breathable fabrics and drying powders to reduce moisture. In recurrent cases, assess for other fungal sites that may reinfect the area.
