This clinical photograph displays the lower face and neck of an elderly male patient with a white beard, showcasing the resolution phase of tinea barbae. The skin in the perioral and submental regions exhibits mild residual erythema and post-inflammatory changes, but lacks the active, suppurative lesions typical of acute sycosiform tinea barbae, such as yellow papules, pustules, or nodular-cystic structures. The beard hair appears clean without significant crusting or matting, indicating a positive response to antifungal therapy (terbinafine). The anatomical focus is on the hair-bearing areas of the face and the upper neck. This image serves as an educational example of the clinical progression and healing of a deep fungal folliculitis after appropriate dermatological treatment, emphasizing the reduction in inflammatory infiltrate and the restoration of normal skin texture in the beard area.

This composite of clinical photographs illustrates the presentation and treatment response of Tinea gladiatorum (tinea corporis), a fungal infection common in contact sports. Panel 1A shows extensive, erythematous, annular plaques with raised borders on the neck and upper chest, demonstrating the characteristic ‘ringworm’ morphology. Panel 1B presents the same patient post-treatment, showing near-complete clinical resolution with minimal residual hyperpigmentation. Panel 1C provides a close-up view of the inflammatory lesions, highlighting the irregular, serpiginous, and papular nature of the raised border. Panel 1D displays a different clinical manifestation on the abdomen: a subtle, hypochromic plaque with fine peripheral desquamation (scaling), representing a localized fungal infection. These images are educational for dermatology and sports medicine, emphasizing the varied clinical appearances of Trichophyton tonsurans infections—from highly inflammatory disseminated lesions to more subtle, scaly plaques—and the efficacy of antifungal therapy.

This clinical photograph displays a dermatological presentation of tinea corporis (ringworm) in a pediatric patient. The primary feature is an annular, erythematous plaque located on the trunk or proximal limb. The lesion is characterized by a well-demarcated, raised red border with evidence of mild scaling or vesiculation, indicating active peripheral growth. The center of the plaque shows partial clearing with a lighter pink hue, though it remains occupied by a few scattered inflammatory papules. Above the primary lesion, incidental linear hyperpigmented marks are visible, likely representing excoriations or minor superficial trauma. The image serves as a classic educational example of a fungal skin infection, specifically demonstrating the centrifugal spread and central clearing characteristic of Microsporum canis dermatophytosis.

This composite of clinical photographs illustrates various clinical presentations of tinea corporis, a common dermatophyte fungal infection. The images depict the characteristic morphology of 'ringworm' across different skin areas. Key diagnostic features visible include well-demarcated, erythematous, annular (ring-shaped) patches and plaques. Several lesions demonstrate classic central clearing, where the center of the ring appears less inflamed than the periphery. The advancing borders are notably active, exhibiting varying degrees of elevation and fine scaling. The presentation varies from discrete, solitary circular lesions to larger, confluent, and irregularly shaped polycyclic patterns. The color intensity ranges from faint pink to vivid red, representing different stages of inflammatory response. These visual characteristics are essential for distinguishing tinea corporis from other annular dermatoses such as nummular eczema, granuloma annulare, or subacute cutaneous lupus erythematosus. The collection serves as an educational tool for identifying the hallmark features of cutaneous fungal infections in a clinical setting.
