Dermatology Education & Helpful Links

We believe informed patients are empowered patients. This section is designed to provide educational resources, clarify common misconceptions, and help explain dermatology-related terms you may hear during your visit.
Whether you are looking to better understand a diagnosis, learn more about skin health, or explore trusted dermatology resources, the information below is intended to support your care.

Common Misconceptions of Dermatology

There are many misunderstandings about what dermatologists do and when dermatologic care is necessary. Below, we address some of the most common misconceptions we hear from patients.

Dermatologists spend the majority of their time working on cosmetic procedures.

Dermatologists devote over 90% of their time caring for medical and surgical conditions, with less than 10% of the time spent on cosmetic procedures. Dermatologists diagnose and treat over 3,000 diseases, ranging from skin cancer to acne to eczema to bacterial infections to very complex medical dermatological conditions such as blistering diseases.

Dermatologists don’t see as many patients as other types of doctors.

At Dermatology Associates of Ithaca, our goal is to make dermatology care as accessible as possible for patients in the Ithaca and surrounding areas. The office is open five days a week with patient appointments available as early as 7:30 AM. We try to see and treat patients as efficiently as possible and to address patients’ skin concerns promptly. Dermatology Associates of Ithaca accepts the widest insurance panel of any Dermatology office in our area so that we can be as accessible as possible to patients needing our care.

If I am scheduled to see the dermatology Physician Assistant (PA) or Nurse Practitioner (NP), that is not as good as seeing the doctor.

Our PA’s and NP’s are highly trained in dermatology, representing several decades’ worth of collective dermatology experience. They then receive close mentorship and supervision from Dr. McAllister to ensure a consistently high quality of dermatology care offered in our office. We believe that our collaborative approach to providing care improves coordination, outcomes, and access for patients. Studies have shown that patients are just as satisfied with medical care provided by physician extenders as with that provided by physicians.

If I wait long enough, this growth on my skin will go away on its own.

A non-healing growth, or wound on your skin that does not resolve on its own within a couple of months, is suspicious for skin cancer. It is important for you to call our office to schedule an appointment for a full skin examination so that we can help find and treat any skin cancers and precancerous lesions as early as possible, since skin cancers will only grow wider and deeper and be more difficult to treat if left alone. Since 2009, Dr. McAllister and her physician extenders have diagnosed and treated hundreds of melanomas in Ithaca, Cortland, and our surrounding areas.

Because I live in Upstate New York, I am not at risk for skin cancer and do not need to wear sunscreen.

It is true that ultraviolet radiation levels are highest near the equator. However, research studies conducted in the northern hemisphere demonstrate increases in melanoma due to recreational and vacation activities related to short periods of intense sun exposure. This perfectly describes the pattern of sun exposure we observe in our community, in that when the long-awaited summer season arrives, participation in outdoor activities such as hiking, gardening, golfing, and swimming results in sunburns, tanning, and ambient UV exposure that adds to an individual’s lifetime accumulated sun exposure and thus skin cancer risk. Furthermore, a significant portion of the population in Ithaca and the surrounding areas travels widely, for example spending winters in Florida, or vacationing in sunnier parts of the world, and traveling also contributes to increased sun exposure that one might otherwise not expect in a resident of upstate New York. In our experience, rates of melanoma are just as high if not higher in our patient population compared to that of the country as a whole, and thus skin cancer screening and sun protection with sunscreen and sun-protective clothing is just as important for residents of Ithaca and the surrounding areas.

Dermatology is not a cost effective use of society’s resources.

Skin disease is second only to trauma as a cause of occupational disability, and accounts for a yearly economic loss to society of over $2 billion. Furthermore, melanoma, the deadliest skin cancer, is responsible for many years of potential life lost as well as significant costs associated with premature mortality and morbidity. Multiple studies have shown that dermatologic care is more cost efficient and of higher quality when provided by a dermatologist than by any other medical professional. For example, according to one study dermatologists correctly diagnose skin disease 98 percent of the time, compared to 60 percent of general practitioners. This allows patients to have their skin disease treated appropriately, in fewer patient visits, and for skin cancers to be detected and treated early. Early detection and treatment of skin cancers particularly allows for the efficient use of health care resources, as the cost of treatment increases exponentially with advanced stages of skin cancer. When a skin cancer is detected early, it can be removed in the dermatologist’s office, which is a simple outpatient procedure under local anesthesia. This is much less expensive and carries a much lower risk of long term health consequences than treating a larger skin cancer under general anesthesia in the hospital or undergoing chemotherapy for skin cancer that has spread to other parts of the body.

Dermatology Terminology

Dermatology includes many medical terms that may be unfamiliar. Below are common terms you may hear during your visit, along with brief explanations.

Actinic Keratoses (AK’s)

Actinic keratoses represent the earliest stage in the development of skin cancer. They are common lesions of the epidermis (outermost layer of the skin), and are caused by long-term exposure to sunlight. AK’s are most likely to appear after age 40, but may be found in people as young as the teens and twenties. The most significant predisposing factors to AK’s are fair skin and long-term sun exposure.

Benign Nevus

Also known as a mole, nevus is the medical term for sharply circumscribed and chronic lesions of the skin. They are also commonly referred to as birthmarks or beauty marks.

Cherry Angiomas

These are cherry red bumps on the skin that represent a proliferation of blood vessels.

Dermatofibroma

This is a very common skin growth that resembles a firm, scar-like bump on the skin after an insect bite or hair follicle inflammation.

Intertrigo

This is a yeast infection in the folds of the skin caused by moisture, warmth, and friction.

Lentigines

Sun freckles

Milia

White or yellow acne-like cysts under the skin

Onychomycosis

Fungal infection of the toenail

Seborrheic Dermatitis

Red, flaky skin affecting the scalp, face or torso, similar to dandruff, caused by yeast overgrowth.

Sebaceous Hyperplasia

Glands that become enlarged, producing yellow, shiny bumps on the face.

Seborrheic Keratoses (SK’s)

Seborrheic Keratoses are often confused with warts or moles, but they are quite different. Seborrheic keratoses are non-cancerous growths of the outer layer of skin. There may be just one growth or many which occur in clusters. They are usually brown, but can vary in color from light tan to black and range in size from a fraction of an inch in diameter to larger than a half-dollar. A main feature of seborrheic keratoses is their waxy, pasted-on or stuck-on appearance. They sometimes look like a dab of warm brown candle wax that has dropped onto the skin or like barnacles attached to the skin. Learn more .

Tinea (Pedis, Corporis, Versicolor, etc.)

Fungal infection in the skin, also known as “ringworm” or “tinea.” An example of a common fungal infection is athlete’s foot, also known as tinea pedis.

Verruca

A wart

Xerosis

Abnormal dryness of the skin

Karen F.

I went for a facial with Reganne, and it was wonderful! She was the right balance of chatty and quiet so that I felt personally welcomed but also able to relax and soak in all the luxurious treatment. She also was so kind and considerate, being very careful which products she used because she knew I am sensitive to some fragrances. I scheduled my appointment for the end of my regular work week, and now, this evening I’m feeling fabulous!

RJ and MJ Olson

We both chose the practice for our dermatology well checks and any issues that may be discovered during those visits. Most of the practitioners have been great. I also enjoy the facial services they offer at the practice. Both estheticians I have seen there have been wonderful! They have both been very accommodating given multiple allergies that can make my skin reactive. I look forward to my time with the esthetician.

Cathy Robinson

The entire staff is courteous and very helpful. They were right on time. They work together well. They are accepting of questions and are willing to answer the questions. They offer reminders for follow up appointments. I am very pleased to be a patient of this office.

Susan Zeller

As a new patient I greatly appreciated getting an appointment with a few days of submitting my application form instead of a long wait. The staff at the front desk were very pleasant, efficient and helpful in making this happen. The service I received from my doctor was good.

Tom

David M was great in all key areas that were important to me. Skill, bedside manner, updates during the surgery and his summary after the procedure. His nurse was also first rate. Thank you both for all that you did for me. NP Donna has treated me previously at this practice and I echo my comments here for her and the nurses, reception and scheduling employees. Thank you all for a great experience

Jennifer Gemmell

This was the most pleasant doctors appointment I’ve ever experienced. The wait wasn’t too long and there were so many beautiful and interesting things to look at while I was there: beautiful art well presented with identification and background details, fascinating terrariums and other plants, and even an Asian meditation garden. Dr. Macallister was very personable, professional and thorough. I was quite happy with her care. The staff too, were professional and pleasant.

Reece W

Saw Donna and Megan, had a concerning spot on my face. I needed an injection and they put me eat ease and really helped me to feel comfortable and relaxed. Even though the needle stung a little bit I was completely distracted with easy conversation to keep my mind off of what was going on. They were incredibly reassuring and informative and I love going to see them! Thank you Donna and Megan for a quick and easy visit! :)

Don Wood

Great experience from the time I arrived for the appointment til I was finished. Donna Brigham is the most professional specailist I've seen in quite some time. She is very good at explaining everything in layman's terms. Her bedside manner puts you at ease and makes you very comfortable with the procedures she is doing.
