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

6. Sebaceous Hyperplasia and Glandular Changes

Sebaceous hyperplasia of the nasal skin represents a common finding in patients with rosacea and certain autoimmune conditions, characterized by enlarged sebaceous glands that create small, yellowish, dome-shaped papules with central umbilication. These benign growths result from the proliferation of sebaceous gland tissue in response to chronic inflammation, hormonal influences, and genetic predisposition, particularly affecting the nose where sebaceous glands are naturally more numerous and larger. In rosacea, sebaceous hyperplasia often accompanies other inflammatory changes and may contribute to the overall textural irregularities and cosmetic concerns associated with the condition. The enlarged glands can become more prominent with age and continued inflammatory stimulation, sometimes requiring differentiation from other conditions such as basal cell carcinoma or sebaceous adenoma. The pathophysiology involves increased sebocyte proliferation and altered sebaceous gland architecture in response to inflammatory mediators, particularly in areas of chronic erythema and vascular changes. In some autoimmune conditions, particularly those involving chronic inflammation or immunosuppressive therapy, sebaceous hyperplasia may develop as a secondary phenomenon. Treatment options include topical retinoids to normalize gland function, laser therapy for cosmetic improvement, and addressing underlying inflammatory conditions to prevent further glandular changes. Recognition of sebaceous hyperplasia is important for comprehensive management of nasal skin changes and patient counseling regarding realistic treatment expectations.
