This composite clinical photograph series illustrates the progression of drug-induced subacute cutaneous lupus erythematosus (SCLE) in a 70-year-old female. Images (a-c) demonstrate the baseline presentation: (a) shows a prominent, symmetric, bright red malar erythema across the cheeks and bridge of the nose, characteristic of a 'butterfly rash'; (b) and (c) display extensive macular erythematous lesions on the upper back, chest, and arms, with some lesions exhibiting an annular or polycyclic morphology. These lesions are well-demarcated, non-scarring, and primarily distributed in sun-exposed areas. Images (d-f) show the clinical outcome one month following the discontinuation of the offending agent (hydrochlorothiazide) and treatment with low-dose systemic steroids. There is a marked reduction in the intensity and distribution of the erythema; the malar rash has significantly faded, and the truncal macular lesions have diminished to faint, sparse pigmented patches. This comparison serves as an educational tool for identifying photosensitive drug-induced cutaneous reactions and monitoring clinical response to drug withdrawal and corticosteroid therapy.

Clinical photograph of a 59-year-old female patient showing a characteristic malar rash. The image displays confluent, erythematous patches distributed over the bilateral cheeks and extending towards the temporal regions, as indicated by black arrows. The rash exhibits a symmetric, butterfly-like distribution, though the nasolabial folds appear relatively spared. The skin within the affected areas shows noticeable texture changes and erythema. Additional visible features include forehead rhytids, perioral lines consistent with age-related skin changes, and uneven pigmentation. The patient has a nose ring in the left nostril. The clinical presentation is consistent with cutaneous lupus erythematosus, specifically a drug-induced manifestation. The educational focus is on identifying classic dermatological signs of systemic inflammatory or drug-induced conditions through facial skin morphology and distribution patterns.

This clinical dermatology photograph displays the classic malar or butterfly rash of systemic lupus erythematosus (SLE) on the central face. Modality is clinical photography using standard white-light illumination; frontal/anterior view; color-balanced, high-resolution capture to depict superficial erythema and patchy hyperemia across the malar eminences and nasal bridge. The rash forms a bilateral, 'butterfly' distribution that typically reaches the cheeks and bridge of the nose while sparing the nasolabial folds. The observed features include confluent to patchy, erythematous macules and plaques with uniform erythema, mild perivascular edema, and subtle textural change without overt crusting or scaling in this image. The clinical morphology is characteristic for acute cutaneous lupus erythematosus; photosensitivity may exacerbate lesions. This cutaneous finding is one of the diagnostic criteria for SLE when aligned with serologic abnormalities (ANA, anti-dsDNA) and systemic features; its presence increases diagnostic probability in a compatible patient. Differential considerations include rosacea, seborrheic dermatitis, contact dermatitis, and dermatomyositis rash; however, the malar distribution and nasal bridge involvement help distinguish lupus. Clinically, this image supports SLE workup and educational reference for recognizing lupus-associated facial rash in medical students, residents, and researchers; useful for pattern-recognition training and multimodal data repository indexing. This image emphasizes clinical-context interpretation and education.

This clinical photograph displays a frontal view of a female patient's face, illustrating a drug-induced cutaneous eruption. The image demonstrates a diffuse, erythematous facial rash with a predominant distribution over the forehead and the malar (butterfly) regions. The erythema is characterized by a pink-to-red hue with an associated fine papular texture, most notably on the bilateral cheeks. Significant sparing is observed in the periorbital (orbicularis oculi) and lower perioral areas. The photograph captures the clinical state seven days following the cessation of a suspected causative agent (metformin), showing a partial resolution with decreased intensity of hyperemia and papular prominence compared to acute presentation. This visual is useful for teaching the morphological characteristics of drug-induced exanthems and their differentiation from dermatological conditions like rosacea or subacute cutaneous lupus erythematosus.
