15 Nose and Nasal Skin Changes Associated With Rosacea and Autoimmune Conditions

6. Dermatomyositis-Related Periorbital and Nasal Changes

Dermatomyositis presents with distinctive cutaneous manifestations that often involve the nasal region as part of the characteristic heliotrope rash and Gottron's papules distribution. The nasal involvement typically manifests as erythematous to violaceous discoloration affecting the nasal bridge and extending toward the periorbital areas, creating a distinctive pattern that helps establish the diagnosis. This photodistributed eruption results from immune-mediated damage to dermal blood vessels and keratinocytes, leading to interface dermatitis and characteristic histopathological changes. The nasal skin may also develop the characteristic scaling and atrophy seen in other sun-exposed areas affected by dermatomyositis. In some cases, patients may develop nasal ulceration or perforation, particularly in the juvenile form of the disease or in cases associated with anti-MDA5 antibodies. The presence of nasal involvement often correlates with disease severity and may indicate increased risk for systemic complications including interstitial lung disease and malignancy in adult patients. Treatment typically involves systemic corticosteroids and immunosuppressive agents, along with aggressive sun protection to prevent exacerbation of photosensitive lesions. The chronic nature of dermatomyositis means that nasal changes may persist even with treatment, requiring long-term management strategies to minimize cosmetic impact and prevent complications such as secondary infection or scarring.
