Medical Dermatology & Chronic Skin Disease Management:

Dr. Hughes provides expert diagnosis and long-term management of a wide spectrum of skin conditions, with particular expertise in psoriasis, eczema, rosacea, and inflammatory skin diseases. For patients living with chronic skin conditions, she develops individualized treatment plans that may include topical therapies, systemic medications, biologic treatments, and phototherapy — tailored to the severity of each patient’s condition and their personal treatment preferences. Her breadth of experience with the diverse range of skin conditions seen in the Pacific Northwest patient population gives her a well-rounded and practical approach to everyday dermatologic challenges.

Skin Cancer Detection & Surgical Treatment:

A significant component of Dr. Hughes’ practice is the early identification and surgical management of skin cancers. She performs comprehensive full-body skin cancer screenings, advanced dermoscopy evaluations, and surgical excision of cancerous and pre-cancerous skin growths including basal cell carcinoma, squamous cell carcinoma, melanoma, and actinic keratoses.
