Expert Complex Medical Dermatology in Clovis & Fresno, CA
At Dehesa Dermatology, we specialize in diagnosing and managing the most challenging skin conditions — the kind that require more than a routine appointment. Our board-certified dermatologist, Dr. Luis A. Dehesa, brings over 20 years of clinical and teaching experience to every patient encounter, providing precise, compassionate care for chronic, autoimmune, and systemic skin diseases. Serving patients throughout Clovis, Fresno, and the greater Central Valley, Dehesa Dermatology is the region’s premier destination for complex dermatologic care.
What Is Complex Medical Dermatology?
Complex medical dermatology is a specialized branch of dermatology focused on diagnosing and treating chronic, autoimmune, inflammatory, and systemic skin diseases that go beyond the scope of general skin care. These conditions often involve multiple organ systems, require advanced diagnostic workups — including skin biopsies, immunofluorescence studies, and laboratory panels — and demand ongoing, coordinated medical management.
Unlike routine dermatology visits, complex cases require deep expertise, careful monitoring, and frequently, collaboration with rheumatologists, immunologists, and other specialists. At Dehesa Dermatology, our multispecialty practice is uniquely positioned to handle this level of care. Our in-house rheumatology department and infusion therapy center allow us to manage even the most advanced inflammatory skin conditions under one roof — a rare offering in the Central Valley.
Conditions We Treat
Our complex medical dermatology team evaluates and manages a wide range of difficult-to-treat skin conditions, including:
- Severe and Treatment-Resistant Psoriasis: Including plaque, guttate, inverse, and pustular psoriasis that has not responded to first-line therapies. We offer advanced biologic treatments and infusion-based options. Learn more about our psoriasis treatment services.
- Chronic Eczema (Atopic Dermatitis): Moderate to severe eczema requiring systemic medications, biologics such as dupilumab, or infusion therapy. See our eczema treatment page for more information.
- Autoimmune Blistering Diseases: Such as pemphigus vulgaris, bullous pemphigoid, and dermatitis herpetiformis — rare and serious conditions requiring immunosuppressive therapy and close follow-up.
- Connective Tissue Disorders with Skin Manifestations: Including lupus erythematosus, dermatomyositis, scleroderma, and mixed connective tissue disease. These often require coordination with our rheumatology team.
- Vasculitis: Inflammation of blood vessels that can present as palpable purpura, ulcerations, or livedo reticularis — requiring systemic evaluation and management.
- Granulomatous Skin Diseases: Including sarcoidosis and granuloma annulare presenting with complex or atypical features.
- Drug Reactions and Hypersensitivity Syndromes: Such as DRESS syndrome, Stevens-Johnson syndrome, and severe urticaria requiring immediate, expert evaluation.
- Complex Acne and Scarring: Acne conglobata, acne fulminans, and nodulocystic acne with significant scarring. Visit our acne treatment page to learn about our full range of acne services.
- Skin Conditions Associated with Internal Disease: Paraneoplastic syndromes, metabolic skin changes, and dermatoses linked to systemic illness.
Our Diagnostic and Treatment Approach
When you come to Dehesa Dermatology with a complex skin condition, you can expect a thorough and methodical evaluation. Our process includes:
- Comprehensive Patient History: A detailed review of your medical history, previous treatments, medication list, family history, and symptom timeline.
- Full-Body Skin Examination: Careful assessment of all skin, hair, nail, and mucous membrane findings, including dermatoscopy when indicated.
- Advanced Diagnostics: In-office skin biopsies with standard and direct immunofluorescence, laboratory panels, patch testing for contact allergens, and referral imaging when needed.
- Personalized Treatment Planning: Targeted therapies ranging from advanced topicals and phototherapy to systemic immunosuppressants, biologics, and in-office infusion treatments at our infusion therapy center.
- Multidisciplinary Coordination: Direct collaboration with Dr. Milena Cavalcante, our board-certified rheumatologist, and with outside specialists as needed to ensure holistic care.
- Long-Term Monitoring: Ongoing follow-up to track disease activity, adjust treatments, watch for medication side effects, and manage flares proactively.
Our approach is never cookie-cutter. We understand that two patients with the same diagnosis can have very different disease courses, treatment responses, and life circumstances — and we adapt our care accordingly.

Frequently Asked Questions About Complex Medical Dermatology
What types of conditions are treated under complex medical dermatology?
Complex medical dermatology addresses chronic and systemic skin diseases such as severe eczema, treatment-resistant psoriasis, autoimmune blistering disorders, connective tissue diseases, vasculitis, drug hypersensitivity reactions, and skin conditions tied to internal disease. These are conditions that typically require advanced diagnostics, systemic therapies, and ongoing specialist management rather than routine topical treatments.
How is complex medical dermatology different from general dermatology?
General dermatology covers a broad range of common skin concerns including acne, moles, rashes, and annual skin checks. Complex medical dermatology focuses specifically on severe, chronic, or multisystem conditions that require deeper diagnostic workups, systemic or biologic medications, and often coordination with other specialists such as rheumatologists or immunologists. At Dehesa Dermatology, our multispecialty setup allows us to offer both under one roof.
Do I need a referral to be seen at Dehesa Dermatology for a complex condition?
In most cases, you do not need a referral to schedule an appointment at Dehesa Dermatology. However, some insurance plans do require a referral from your primary care physician before seeing a specialist. We recommend checking with your insurance provider ahead of your visit. Call us at (559) 951-9000 and our team can help guide you through the process.
What should I bring to my first complex dermatology appointment?
Please bring a valid photo ID, insurance card, a complete list of your current medications and supplements, any prior biopsy or lab reports related to your skin condition, and the names of any other specialists currently treating you. The more information you can share upfront, the more efficiently we can evaluate and develop a care plan tailored to your needs.
Can Dehesa Dermatology coordinate care with my other doctors?
Yes. Coordinated, multidisciplinary care is a cornerstone of what we do. Dr. Dehesa and our team regularly communicate with primary care physicians, rheumatologists, gastroenterologists, oncologists, and other specialists to ensure your care is cohesive and comprehensive. Patients with autoimmune conditions especially benefit from this approach, as these diseases often affect multiple organ systems simultaneously.
Are biologic medications available at your practice for skin conditions?
Yes. Dehesa Dermatology is equipped to prescribe and administer biologic medications for qualifying patients with moderate to severe skin conditions such as psoriasis and atopic dermatitis. Some biologics are self-injected at home, while others are administered intravenously at our on-site infusion therapy center. Our providers will walk you through all available options and help you navigate insurance prior authorization.
Does Dehesa Dermatology see patients from Fresno for complex skin conditions?
Absolutely. We serve patients from throughout the Fresno metro area, Clovis, Madera, and the broader Central Valley. Dr. Dehesa is a Fresno-area native by way of family and spent years teaching dermatology at UCSF Fresno, so he is deeply committed to serving this community.
