• Nail Unit Tumors (Benign & Malignant): Various growths that can occur in or around the nail unit, including benign (e.g., glomus tumor, myxoid cyst) and malignant (e.g., squamous cell carcinoma, melanoma) tumors.

Inflammatory & Immune-Mediated Skin Conditions

• Dermatomyositis: An inflammatory disease marked by muscle weakness and a distinctive skin rash, often on the face, eyelids (heliotrope rash), knuckles (Gottron's papules), and chest.
• Psoriasis (Plaque, Guttate, Inverse, Pustular, Erythrodermic): An autoimmune disease characterized by patches of abnormal skin that are typically red, itchy, and scaly due to rapid skin cell turnover. Can also affect nails and joints (psoriatic arthritis).
• Rosacea (Erythematotelangiectatic, Papulopustular, Phymatous, Ocular): A common skin condition that causes redness, visible blood vessels, flushing, and sometimes small, red, pus-filled bumps on the face. Can also affect the eyes.

Hair & Scalp Disorders

• Androgenetic Alopecia (Male/Female Pattern Hair Loss): A common hereditary form of hair loss characterized by a receding hairline and thinning crown in men, and diffuse thinning over the top of the scalp in women.
• Telogen Effluvium: A type of temporary, diffuse hair shedding often triggered by significant stress, illness, surgery, nutritional deficiencies, or hormonal changes (e.g., postpartum).
• Alopecia Areata (Patchy, Totalis, Universalis, Ophiasis): An autoimmune disorder causing hair to fall out, often in round patches. Can affect scalp, beard, eyebrows, eyelashes, or entire body.

This list is not exhaustive. For personalized advice regarding your specific dermatological condition, please consult with Dr. Derek To.

• Diagnostic Mycology (Fungal Scrapings & Cultures): Collecting skin, hair, or nail samples to identify fungal infections through microscopic examination (e.g., KOH prep) or fungal culture.

• Interpretation of Dermatopathology Reports & Second Opinions: Expert analysis of skin biopsy results to confirm diagnoses, guide treatment strategies, and provide second opinions on complex dermatopathology cases.
• Sclerotherapy for Spider & Small Varicose Veins: Injectable treatment (e.g., with polidocanol or hypertonic saline) to eliminate small, unsightly veins (telangiectasias and reticular veins) primarily on the legs.
• Cosmetic Mole Removal & Skin Tag Removal: Removal of benign moles or skin tags for aesthetic reasons, typically after dermatoscopic confirmation that the lesion is not suspicious for cancer.
• Management of Autoimmune Skin Diseases (Lupus, Dermatomyositis, Pemphigus, Pemphigoid, Vasculitis): Diagnosis and treatment of autoimmune connective tissue diseases with skin manifestations and autoimmune blistering diseases, often in collaboration with rheumatologists or other specialists. May involve topical, oral, or biologic therapies.

Are consultations and dermatological treatments with Dr. To, a Dermatologist, covered by Medical Services Plan (MSP) in BC?

Medically necessary consultations with a licensed Dermatologist like Dr. To, diagnostic procedures (e.g., skin biopsies), and treatments for provincially insured skin conditions (e.g., psoriasis, severe eczema, skin cancer, infections) are generally covered by Medical Services Plan (MSP) in BC when a referral from a family doctor is in place. Purely cosmetic procedures (e.g., Botox for wrinkles, most laser hair removal, fillers for aesthetic enhancement) are typically not covered and are self-pay. It's crucial to discuss coverage specifics for any proposed treatment with Dr. To's office or Medical Services Plan (MSP) beforehand, especially if there's a potential cosmetic component.

Do I need a referral to see Dr. To, a Dermatologist?

Yes, for medically necessary dermatological care covered by the provincial health plan, a referral from your family physician or another specialist (e.g., an ER doctor for an acute issue) is almost always required to see a Dermatologist such as Dr. To. This ensures coordinated care and that your visit is appropriate for specialist assessment. Some dermatologists may offer consultations for uninsured cosmetic services without a referral, but these would be a direct cost to you. Always check with the clinic regarding their specific referral policy.

What kind of sunscreen does Dr. To recommend?

While specific brand recommendations can vary, Dr. To would likely advise choosing a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF (Sun Protection Factor) of 30 or higher. For daily use, a lighter formulation might be preferred, while for prolonged outdoor activities, water-resistant sunscreen is important. Consider your skin type: individuals with sensitive skin might prefer mineral-based sunscreens containing zinc oxide or titanium dioxide. The most important thing is to apply sunscreen generously and reapply it every two hours, or more often if swimming or sweating. Dr. To can provide personalized recommendations based on your skin type and lifestyle during your consultation.

How should I prepare for my first dermatology appointment with Dr. To?

To make the most of your first visit with Dr. To, it's helpful to: 1. Make a list of your skin concerns, symptoms (e.g., itch, pain, duration), and any treatments you've already tried (both prescription and over-the-counter). 2. Bring a list of all your current medications, including vitamins and supplements. 3. Be prepared to discuss your personal and family medical history, including any history of skin cancer or significant skin conditions. 4. For a full skin exam, it's best to wear loose, comfortable clothing that is easy to remove and avoid wearing makeup or nail polish. 5. If your concern involves a rash that comes and goes, taking clear photos when it's visible can be very helpful. 6. Write down any questions you have for Dr. To.

If Dr. To recommends phototherapy, what does that involve?

Phototherapy, also known as light therapy, is a medical treatment where your skin is exposed to specific wavelengths of ultraviolet (UV) light under strict medical supervision. Dr. To might recommend it for conditions like psoriasis, eczema, vitiligo, or cutaneous T-cell lymphoma. Treatments are typically given 2-3 times a week in a specialized light cabinet or with a handheld device for smaller areas. The type of UV light (e.g., Narrowband UVB, PUVA) and treatment duration are carefully controlled. It works by reducing inflammation and slowing down the rapid growth of skin cells. You'll be given specific instructions, including eye protection.

What is the difference between a Dermatologist and an Esthetician?

A Dermatologist, like Dr. To, is a medical doctor (MD) who has completed medical school followed by several years of specialized residency training in dermatology. They are qualified to diagnose and treat over 3,000 diseases of the skin, hair, and nails, prescribe medications, perform surgical procedures (like skin cancer removal), and manage complex skin conditions. An Esthetician (or Aesthetician) is a skincare professional trained in cosmetic skin treatments and services that improve the appearance of the skin, such as facials, superficial chemical peels, microdermabrasion, waxing, and makeup application. They are not medical doctors and cannot diagnose skin diseases, prescribe medications, or perform medical or surgical procedures.
