Acne, Rosacea & Follicular Disorders

• Keratosis Pilaris: A common, harmless condition causing small, rough bumps on the skin, usually on the upper arms, thighs, cheeks, or buttocks, due to keratin buildup in hair follicles.

Skin Cancers, Precancerous Lesions & Benign Growths

• Actinic Keratosis (Solar Keratosis): A rough, scaly patch on sun-exposed skin that is considered precancerous and can sometimes progress to squamous cell carcinoma if left untreated.
• Basal Cell Carcinoma (BCC): The most common type of skin cancer, typically slow-growing and arising from sun-exposed skin, appearing as a pearly or waxy bump, flat flesh-colored or brown scar-like lesion, or a bleeding/scabbing sore.

Nail Disorders (Onychopathies)

• Beau's Lines & Other Nail Dystrophies: Transverse depressions in the nails (Beau's lines) or other changes in nail texture or appearance that can indicate systemic illness, trauma, or nutritional deficiencies.
• Ingrown Toenails (Onychocryptosis): A condition where the corner or side of a toenail grows into the soft flesh, causing pain, redness, swelling, and potential infection.

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

• 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.
• 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.
• Nail Surgery (e.g., Ingrown Toenail Removal/Matrixectomy, Nail Biopsy, Tumor Excision): Surgical procedures to treat painful or diseased nails, including permanent correction of ingrown toenails or removal of nail unit tumors.
• 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.
• 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.
• Microneedling (Collagen Induction Therapy) & Radiofrequency (RF) Microneedling: Procedures that create controlled micro-injuries in the skin to stimulate collagen and elastin production, improving skin texture, reducing scars (acne, surgical), fine lines, and stretch marks. RF Microneedling combines microneedling with radiofrequency energy for enhanced skin tightening and rejuvenation.
• Patch Testing for Allergic Contact Dermatitis (Standard & Expanded Panels): Diagnostic procedure to identify specific allergens causing contact dermatitis by applying small amounts of common (and sometimes occupational or specialized) allergens to the skin.

Are consultations and dermatological treatments with Dr. Vignjevic, a Dermatologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations with a licensed Dermatologist like Dr. Vignjevic, 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 Ontario Health Insurance Plan (OHIP) in ON 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. Vignjevic's office or Ontario Health Insurance Plan (OHIP) beforehand, especially if there's a potential cosmetic component.

Do I need a referral to see Dr. Vignjevic, 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. Vignjevic. 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.

When should someone consider seeing a Dermatologist like Dr. Vignjevic?

A referral to a Dermatologist like Dr. Vignjevic is often recommended by a family physician for: any new or changing moles or skin growths; persistent or severe skin rashes (e.g., eczema, psoriasis) not responding to initial treatments; severe or cystic acne; chronic hives; significant hair loss or scalp disorders; problematic nail conditions (e.g., persistent fungal infections, unusual changes); suspected skin infections; or for expert skin cancer screening, especially if you have risk factors like a personal or family history of skin cancer, numerous moles, or significant sun exposure. Early consultation can be key for effective management and diagnosis.

What is the difference between a Dermatologist and an Esthetician?

A Dermatologist, like Dr. Vignjevic, 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.
