Two color clinical photographs (a and b) show extensive skin lesions on a patient's abdomen and back, characteristic of Tinea corporis. Panel (a) displays the abdominal region with large, well-defined erythematous (reddish) plaques. These plaques exhibit irregular, polycyclic margins and some central clearing, creating a mosaic-like pattern interspersed with normal-appearing skin. Panel (b) shows the back, where the lesions are more confluent and densely packed, presenting as diffuse erythematous areas with scaling and a plaque-like texture. The morphology is consistent with a dermatophyte infection, demonstrating classic fungal skin manifestations including circular or annular arrangements and progressive spread. These images are used in medical education to teach the clinical recognition of extensive fungal dermatosis and its potential systemic or ocular associations, such as retinochoroiditis in immunocompromised or non-compliant patients.

This composite clinical figure demonstrates the multisystemic resolution of a fungal infection (Tinea corporis) after two weeks of antifungal treatment. Image A is a fundus photograph of the left eye showing the posterior pole and mid-periphery. It reveals a resolving retinochoroiditis lesion, characterized by a diffuse, faint yellowish patch with irregular margins located along the inferotemporal vascular arcade. The optic disc, macula, and remaining vasculature appear stable. Image B is a clinical photograph of the abdomen showing multiple resolving skin lesions. These present as scattered, pinkish-red erythematous patches and plaques with less distinct borders compared to the acute phase, set against otherwise normal-appearing skin. The figure highlights the clinical correlation between ophthalmologic findings and dermatologic manifestations in systemic or co-occurring fungal disease, illustrating the typical visual progression of healing during therapeutic intervention.

This clinical photograph displays a dermatological presentation of tinea corporis (zoonotic dermatophytosis) on the abdomen of an adult male. The primary feature is a well-circumscribed, annular, erythematous plaque approximately 4-5 cm in diameter. The lesion exhibits a classic 'ringworm' morphology with a slightly raised, scaly inflammatory border and a partially cleared central area containing subtle papular elements. Superior to the primary plaque is a secondary, smaller, raised erythematous papule with a central punctum or crust. The surrounding skin shows mild diffuse erythema and scattered smaller inflammatory macules. Hair follicles are visible throughout the affected and unaffected regions. This image serves as an educational example of fungal infection (likely Trichophyton mentagrophytes) transmitted from a pet (guinea pig) to a human host, emphasizing the visual diagnostic features of annular inflammatory skin lesions.

This composite figure provides a clinical and laboratory overview of a dermatophytosis infection caused by Trichophyton mentagrophytes Type VIII. Images (a) and (b) are clinical photographs displaying classic signs of tinea corporis. Photograph (a) shows the abdomen with multiple erythematous, annular (ring-shaped) lesions featuring raised, active red borders and central clearing. Photograph (b) depicts large, coalescing, arcuate plaques on the thigh with peripheral scaling and varying degrees of erythema. Image (c) is a diagnostic microbiology photograph showing a subculture of the isolate on Sabouraud's dextrose agar. The fungal colonies are fast-growing, characterized by a white, granular texture with flat, radiating margins. This visual set demonstrates the correlation between dermatological manifestations and mycological identification for an emerging anthropophilic fungal variant. The content is suitable for medical education regarding fungal skin infections, diagnostic dermatology, and medical mycology.
