Red scalp is a common complaint which may constitute a diagnostic and therapeutic challenge in daily clinical practice. Among the numerous diseases which cause diffuse scalp erythema are psoriasis, seborrheic dermatitis, contact dermatitis, diffuse lichen planopilaris, dermatomyositis and scalp rosacea. Accurate diagnosis is crucial for optimal treatment outcomes. Histology most frequently discriminates the underlying condition, but it requires scalp biopsy. In many cases the combination of clinical examination and trichoscopy is sufficient for establishing the correct diagnosis. The main trichoscopic features of psoriasis are silver-white scaling, regular distributed dotted (glomerular) vessels or twisted red loops and punctate hemorrhages. Yellowish-white scaling and thin arborizing vessels are typical features of seborrheic dermatitis. Contact dermatitis is characterized by the presence of yellow exudate and polymorphic vessels, while perifollicular scaling and erythema with the lack of follicular openings are typical findings in lichen planopilaris. In scalp dermatomyositis, tortuous and arborizing vessels with interfollicular and perifollicular pigmentation may be detected. The most characteristic features of scalp rosacea are perifollicular scaling and arborizing vessels. This review also summarizes histologic features and therapeutic options for these conditions.
