Tinea Capitis Scalp Infection

Description

Posterior scalp and upper shoulders of an adult male are shown, with multiple round to oval patches on the occipital and parietal cranial integument. Lesions appear lighter than the surrounding skin and cluster across the vertex-to-occiput region, where terminal hair density is reduced, consistent with patchy alopecia. Subtle surface scale at the patch margins is suggested by the tonal texture change, a common clue when dermatophyte infection involves the stratum corneum and hair shafts. The nuchal hairline and posterior neck provide clear anatomic orientation. Tinea capitis in adults is less common than in children, so the morphology and distribution matter when you are separating dermatophytosis from noninfectious causes of depigmented scalp patches such as vitiligo, postinflammatory hypopigmentation, alopecia areata, or traction-related loss. Round patches with scale point you toward a fungal etiology, and the occipital location aligns with patterns seen in Trichophyton species spread by close contact, contaminated clippers, or household fomites. Missed tinea capitis is not benign. Delay in systemic therapy can progress to inflammatory kerion and permanent scarring alopecia, and asymptomatic carriers can perpetuate outbreaks in families, barbershops, and athletic settings. Dermatology and primary care educators use this type of posterior scalp view when teaching lesion recognition, differential diagnosis of alopecia, and indications for potassium hydroxide prep, fungal culture, dermoscopy, or Wood lamp examination in suspected dermatophytosis. Medical publishers often pair it with treatment content on oral terbinafine or griseofulvin and counseling on decontamination and contact screening in community-acquired scalp mycoses.
