Skin Conditions Treated in Clovis & Fresno, CA
At Dehesa Dermatology, we diagnose and treat a comprehensive range of skin conditions — from the most common to the most complex. Board-certified dermatologist Dr. Luis A. Dehesa brings over 20 years of clinical expertise to every patient encounter, providing accurate diagnosis and evidence-based treatment for patients throughout Clovis, Fresno, and the greater Central Valley. Whatever is happening with your skin, our team has seen it before and has the tools and training to address it effectively.
Common Skin Conditions We Treat
The Central Valley’s intense sun exposure, warm climate, and diverse patient population create a wide range of dermatologic needs. At Dehesa Dermatology, our practice is built to address all of them — from precancerous sun damage and skin cancer to chronic inflammatory conditions, autoimmune skin diseases, infections, and cosmetic concerns. Below is a guide to the skin conditions we treat and what you can expect from care at our practice.
Inflammatory & Autoimmune Skin Conditions
- Psoriasis — A chronic autoimmune condition causing thick, scaly plaques on the skin. We offer the full spectrum of treatment including topical therapy, phototherapy, systemic medications, and the most advanced biologic therapies available — including IV biologics through our on-site infusion center. Integrated rheumatology care is available on-site for patients with psoriatic arthritis.
- Eczema (Atopic Dermatitis) — Chronic inflammatory skin disease causing dry, itchy, inflamed skin. We manage eczema for patients of all ages including advanced biologic therapy such as dupilumab for moderate to severe cases.
- Rosacea — A chronic facial skin condition causing persistent redness, flushing, visible blood vessels, and acne-like breakouts. We offer topical and oral therapies as well as laser treatment for redness and vascular lesions.
- Contact Dermatitis — Inflammatory skin reactions triggered by irritants or allergens. We provide professional patch testing to identify specific allergens and personalized treatment and avoidance strategies for both irritant and allergic contact dermatitis.
- Hives (Urticaria) — Sudden, itchy raised welts on the skin. We treat both acute and chronic urticaria, including omalizumab (Xolair) for patients with chronic hives that don’t respond to antihistamines.
- Vitiligo — An autoimmune condition causing loss of skin pigmentation in patches. We offer the latest repigmentation therapies including topical ruxolitinib cream (Opzelura) and narrowband UVB phototherapy.
Skin Cancer & Precancerous Conditions
- Skin Cancer — We provide complete skin cancer care including full-body dermoscopic screening exams, in-office biopsy, surgical excision, and fellowship-trained Mohs surgery. We treat all types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.
- Melanoma — The most dangerous form of skin cancer. Expert detection and surgical management by fellowship-trained Mohs surgeon Dr. Dehesa — one of very few in the Clovis-Fresno area.
- Actinic Keratosis — Precancerous rough, scaly patches caused by cumulative UV damage. Highly prevalent in Central Valley residents. Treated with cryotherapy, topical field therapy, and photodynamic therapy before progression to squamous cell carcinoma occurs.
- Moles — Professional mole evaluation using dermoscopy, biopsy for suspicious lesions, and removal for medical or cosmetic reasons. Essential for patients with a history of melanoma, numerous moles, or changing growths.
Hair & Scalp Conditions
- Hair Loss (Alopecia) — Expert evaluation and treatment of all types of alopecia — androgenetic alopecia, alopecia areata, telogen effluvium, traction alopecia, and scarring alopecias. Treatment options include PRP therapy, JAK inhibitors, topical and oral minoxidil, spironolactone, and intralesional injections.
Infections & Growths
- Warts — Professional wart removal with substantially higher clearance rates than over-the-counter products. We offer cryotherapy, cantharidin, intralesional immunotherapy, and laser treatment for all wart types including plantar and periungual warts.
- Fungal Skin Infections — Treatment for athlete’s foot, ringworm, jock itch, nail fungus (onychomycosis), tinea versicolor, scalp ringworm, and cutaneous candidiasis. Dr. Dehesa has specific research expertise in nail fungus management.
- Cysts & Lipomas — In-office evaluation and surgical removal of epidermoid cysts, pilar cysts, lipomas, and other benign skin tumors with meticulous technique and minimal scarring.
Pigmentation & Structural Skin Changes
- Seborrheic Keratosis — Evaluation and removal of these common benign “stuck-on” skin growths through cryotherapy, electrodesiccation, or laser treatment. Accurate differentiation from more serious conditions using dermoscopy.
- Scars & Keloids — Comprehensive scar management including intralesional corticosteroid injections, laser resurfacing, microneedling, and 5-fluorouracil for keloids — as well as treatment for atrophic acne scars and post-inflammatory hyperpigmentation.
Nail Conditions
- Nail Disorders — Expert diagnosis and treatment of nail fungus, psoriatic nail disease, melanonychia (dark nail streaks), ingrown toenails, paronychia, and brittle nails. Dr. Dehesa has specific fellowship research expertise in onychomycosis.
Additional Conditions We Treat
The conditions listed above represent the most common presentations at our practice, but the scope of dermatology is far broader.

Serving Patients from Clovis, Fresno & the Central Valley
Many of the skin conditions above are particularly prevalent in the Central Valley — where intense year-round UV exposure, warm temperatures, and an outdoor-active population create elevated rates of sun damage, skin cancer, fungal infections, and inflammatory flares.

We are located at 978 N Temperance Ave in Clovis, CA, just minutes from Fresno via Highway 168, and welcome patients from Madera, Selma, Sanger, Reedley, and beyond.

Frequently Asked Questions About Skin Conditions
How do I know which skin condition I have?
Many skin conditions look similar to the untrained eye — rashes, red patches, and scaling can be caused by dozens of different conditions, each requiring a different treatment approach. Self-diagnosis and over-the-counter product experimentation often leads to months of frustration with no improvement. The most reliable path to an accurate diagnosis — and effective treatment — is a professional evaluation by a board-certified dermatologist like Dr. Dehesa at Dehesa Dermatology. In most cases, we can provide a diagnosis and treatment plan at your first visit.
Can the same rash be caused by different conditions?
Yes — this is one of the core challenges of dermatology. Eczema, psoriasis, contact dermatitis, fungal infections, and several other conditions can all produce red, scaly, itchy patches that look almost identical. Accurate diagnosis requires examining the distribution, characteristics, and associated features of the rash in combination with patient history and sometimes laboratory testing or biopsy. At Dehesa Dermatology, Dr. Dehesa uses dermoscopy and in-office diagnostics to ensure every diagnosis is correct before treatment begins.
Do you treat skin conditions caused by or associated with other medical conditions?
Yes — and this is one of the key advantages of our multispecialty practice. Many skin conditions are manifestations of or associated with systemic diseases: psoriasis and psoriatic arthritis, lupus and connective tissue disease, dermatomyositis, scleroderma, and others. At Dehesa Dermatology, our on-site rheumatology team works directly with Dr. Dehesa to evaluate and manage conditions that span dermatology and rheumatology — providing integrated care that most practices cannot offer.
Are chronic skin conditions like psoriasis and eczema treatable?
Absolutely. While conditions like psoriasis and eczema are currently not curable, modern treatments — including biologic therapies — allow the majority of patients to achieve near-complete or complete clearance and maintain that clearance long-term. The treatment landscape has advanced dramatically in the past decade, and patients who haven’t seen a dermatologist recently may be unaware of how much better their options are now. If you’ve been told your condition is “just something you have to live with,” we encourage you to come in for a consultation.
How do I schedule an appointment for a skin condition at Dehesa Dermatology?
Call (559) 951-9000 Monday through Friday between 8:00 a.m. and 5:00 p.m., or request an appointment online at dehesadermatology.com. New patient intake forms are available on our website to complete before your first visit. We are actively accepting new patients from Clovis, Fresno, and throughout the Central Valley. For urgent skin concerns, please mention this when you call — our team will make every effort to accommodate you promptly.
Does Dehesa Dermatology treat skin conditions in patients from Fresno?
Yes — we serve patients from Fresno, Clovis, Madera, Selma, Sanger, Reedley, and communities throughout the San Joaquin Valley. Our office at 978 N Temperance Ave in Clovis is just minutes from Fresno via Highway 168. Dr. Dehesa is fully bilingual in English and Spanish, and our practice is designed to be accessible to every patient in our community regardless of background or language.
What should I bring to my first appointment for a skin condition?
Bring a valid photo ID, your insurance card, a complete list of current medications and supplements, any prior records or biopsy reports related to your skin concern, and the names of other treating physicians. If you are being evaluated for a rash or skin lesion, avoid applying makeup, lotion, or nail polish to the affected area on the day of your visit so our team can examine it clearly. Arriving 10 to 15 minutes early allows time for any remaining check-in paperwork.
