Inflammatory & Immune-Mediated Skin Conditions

  • Cutaneous Lupus Erythematosus (Discoid, Subacute, Acute): Skin manifestations of lupus, an autoimmune disease, which can range from scaly, disc-shaped lesions to widespread rashes triggered by sun exposure.
  • 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.

Acne, Rosacea & Follicular Disorders

  • Folliculitis (Bacterial, Fungal, Non-infectious): Inflammation of hair follicles, often caused by infection (e.g., Staph aureus, Malassezia) or irritation, leading to itchy or painful bumps, sometimes with pustules.
  • Acne Vulgaris (Comedonal, Papulopustular, Nodulocystic): A common skin condition characterized by pimples, blackheads, whiteheads, and sometimes deeper cysts and nodules, occurring when hair follicles become clogged with oil and dead skin cells. Severity can vary.
  • Hidradenitis Suppurativa (Acne Inversa): A chronic, recurrent inflammatory skin condition featuring painful, deep-seated lumps, abscesses, sinus tracts, and scarring, typically in areas where skin rubs together (axillae, groin, under breasts).

Hair & Scalp Disorders

  • Seborrheic Dermatitis of the Scalp (Dandruff): A common condition causing scaly patches, red skin, and stubborn dandruff on the scalp. Can also affect oily areas of the body.
  • Tinea Capitis (Scalp Ringworm): A fungal infection of the scalp and hair shafts, common in children, causing scaly patches, hair loss, and sometimes inflammation.
  • Cicatricial Alopecia (Scarring Alopecia - e.g., Lichen Planopilaris, Frontal Fibrosing Alopecia, CCCA): A group of rare disorders that destroy hair follicles, replace them with scar tissue, and cause permanent hair loss. Examples include Lichen Planopilaris, Frontal Fibrosing Alopecia, and Central Centrifugal Cicatricial Alopecia.

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

  • Nail Disorder Treatment (Fungal Infections, Psoriasis, Lichen Planus, Ingrown Nails, Tumors): Diagnosis and management of conditions affecting the nails, including infections, inflammatory disorders (like nail psoriasis or lichen planus), structural abnormalities, ingrown nails, and benign or malignant nail unit tumors.
  • Cyst Excision and Drainage of Abscesses: Surgical removal of various types of skin cysts (e.g., epidermoid, pilar) and incision and drainage for skin abscesses.
  • Mohs Micrographic Surgery for High-Risk Skin Cancers: Specialized surgical technique for removing complex or high-risk skin cancers (especially on the head, neck, hands, feet, genitals) with maximal tissue preservation by examining 100% of the surgical margin intraoperatively.
  • 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.
  • Treatment for Skin Infections (Bacterial, Fungal, Viral, Parasitic): Diagnosis and treatment of various skin infections, such as impetigo, cellulitis, erysipelas, ringworm (tinea), athlete's foot, nail fungus (onychomycosis), warts, molluscum contagiosum, herpes simplex/zoster, and scabies.
  • Phototherapy (Narrowband UVB, Broadband UVB, PUVA, Excimer Laser): Controlled administration of specific wavelengths of ultraviolet light to treat various skin conditions such as psoriasis, eczema, vitiligo, and cutaneous T-cell lymphoma.
  • Medical-Grade Facials & Skincare Consultations: Professional facial treatments tailored to specific skin concerns and expert advice on developing an optimal at-home skincare regimen using medical-grade products.

Note: This list provides a general overview of medical and potentially some cosmetic services. Treatment plans are highly individualized. Discuss with Dr. MacLellan for care relevant to your specific condition. Coverage for services varies; medically necessary treatments are typically covered by provincial health plans, while cosmetic procedures are usually self-pay.

All medical and surgical services (if applicable) are provided in accordance with the standards of practice set by the College of Physicians and Surgeons of Ontario (CPSO) and relevant dermatological care guidelines. Contact the clinic or your referring physician regarding new patient intake and referral processes.

Are consultations and dermatological treatments with Dr. MacLellan, a Dermatologist, covered by Ontario Health Insurance Plan (OHIP) in ON?
Medically necessary consultations with a licensed Dermatologist like Dr. MacLellan, 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. MacLellan'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. MacLellan, 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. MacLellan. 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.
How often should I see a Dermatologist like Dr. MacLellan for skin cancer screening?
The recommended frequency for skin cancer screenings by a Dermatologist like Dr. MacLellan varies based on your individual risk factors. These include a personal or family history of skin cancer (especially melanoma), having many moles (e.g., >50) or atypical moles, fair skin that burns easily, a history of excessive sun exposure or tanning bed use, or a suppressed immune system. Your family doctor can assess your risk, or Dr. MacLellan can provide a personalized recommendation after an initial consultation. Regardless of professional check-ups, performing monthly self-skin exams to monitor for any new or changing lesions (using the ABCDEs of melanoma as a guide) is crucial for early detection.
What are the general risks and benefits of cosmetic procedures Dr. MacLellan might offer?
The benefits of cosmetic procedures offered by a qualified Dermatologist like Dr. MacLellan can include improvement in skin appearance, texture, tone, reduction of wrinkles or scars, and enhanced self-confidence. However, all procedures carry some risks. Common risks for minimally invasive cosmetic treatments (like injectables or lasers) can include temporary redness, swelling, bruising, pain, or itching at the treatment site. Less common risks might include infection, allergic reaction, changes in skin pigmentation, or unsatisfactory results. More invasive procedures have different risk profiles. Dr. MacLellan will discuss the specific risks, benefits, and expected outcomes of any proposed cosmetic procedure in detail during your consultation to help you make an informed decision.
How should I prepare for my first dermatology appointment with Dr. MacLellan?
To make the most of your first visit with Dr. MacLellan, 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. MacLellan.
What kind of sunscreen does Dr. MacLellan recommend?
While specific brand recommendations can vary, Dr. MacLellan 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. MacLellan can provide personalized recommendations based on your skin type and lifestyle during your consultation.
