Inflammatory Seborrheic Dermatitis

Description

Erythematous, fine-scaled plaques involve the central face of an adult male, distributed symmetrically along the glabella, eyebrows, nasolabial folds, and perioral beard area, with extension toward the anterior hairline consistent with scalp involvement. Flaking is most apparent on the medial cheeks and around the alar creases, where greasy scale tends to collect, while surrounding facial skin remains less inflamed. Patchy erythema on the presternal chest can be present as a contiguous seborrheic pattern. Scale dominates. Seborrheic dermatitis targets sebum-rich sites and often tracks with Malassezia-associated inflammation, so a mid-face and scalp presentation helps distinguish it from allergic contact dermatitis (more diffuse, pruritic, and boundary-driven) or periorificial dermatitis (papulopustular, classically sparing the vermilion). This facial distribution also forces the common psoriasis comparison: psoriasis tends to produce thicker, sharply demarcated plaques and frequently reaches beyond the hairline, while seborrheic dermatitis favors thinner, yellow-white scale within the eyebrows and nasolabial folds. In practice, this view supports bedside teaching on morphology, symmetry, and regional pattern recognition, and it pairs well with treatment discussions around antifungal shampoos for scalp dandruff and low-potency topical corticosteroids or calcineurin inhibitors for the face. Use this asset in dermatology lectures on inflammatory facial rashes, problem-based learning cases on dandruff and scalp pathology, or clinical handouts explaining recurrent seborrheic dermatitis in adult men. It also fits medical publishing needs for chapters on papulosquamous disorders, differential diagnosis of mid-facial erythema, and patient communication materials where realistic skin texture matters.
