Jennifer Ranario, MD, FAAD


Board-Certified Dermatologist
Fellowship-Trained Mohs Surgeon
Fellow of the American Academy of Dermatology

 

Jennifer Ranario, MD, specializes in Mohs skin cancer surgery and is board certified by the American Board of Dermatology.

Dr. Jennifer Ranario graduated with the highest honors from The University of Texas at Austin. She then earned her Medical Doctorate and MBA from Texas Tech University Health Sciences Center, where she went on to complete her dermatology residency. She pursued further training in Mohs micrographic surgery as part of a procedural dermatology fellowship at the University of Texas MD Anderson Cancer Center in Houston, Texas.

She is a member of the American Academy of Dermatology, Texas Dermatological Society, and the American Society of Dermatologic Surgery. Dr. Jennifer Ranario has performed research and case studies on skin cancer and dermatologic surgery, and she has presented her work at numerous local, regional, and national dermatology conferences. Her work has also been published in multiple peer-reviewed medical journals.

She was drawn to dermatology because she knows things on the skin can affect both self-image and quality of life. She became a Mohs surgeon because she enjoys the delicate nature of the process and paying attention to tiny details. With Mohs surgery, she can also see for herself through a microscope that skin cancer is gone, and she finds it rewarding to provide the treatment with the highest cure rate for most skin cancers.

When not in surgery, she and her husband love hanging out on beaches and seeking out foods from other cultures. Her favorite place they’ve traveled to is Koh Chang Island because of the beautiful beaches and brightly flavored food. Dr. Jennifer Ranario also has an interest in international health and has volunteer experiences in Nicaragua, Mexico, and the Philippines. She and her husband recently welcomed their first child, and they are thrilled to be returning to Austin with their dogs Mandu (“dumpling”) and Batman. She enjoys being outdoors by the water and taking in hill country views, and her favorite place in Austin is Mozart’s Coffee. She loves desserts and can’t live without her KitchenAid, which she regularly uses to make cupcakes and cakes. Because of her cautious and soft-spoken nature, many are surprised to learn that she has been skydiving and gets really into video games like Guitar Hero.

Services Offered By Dr. Jennifer Ranario

What Is Actinic Keratosis?

Actinic Keratosis, also known as solar keratosis, is a scaly or crusty lesion on the skin that develops slowly and indicates the presence of sun damage. It is most commonly found on parts of the body frequently exposed to the sun including the bald scalp, face, ears, lips, backs of the hands or forearms, neck, and shoulders.

Actinic keratosis improves just two days after a freezing removal treatment.

Actinic keratoses are considered precancerous and can develop into a type of skin cancer called squamous cell carcinoma. In fact, some 40 to 60 percent of squamous cell skin cancers begin as untreated actinic keratoses.

Because of this, your doctor should be diligent in diagnosing, treating and monitoring actinic keratosis.

What Is Basal Cell Carcinoma?

Basal Cell Carcinoma, also known as basalioma or basal cell cancer, is the most common type of skin cancer and carries the least amount of risk, though it still requires attention. If caught and treated early, basal cell carcinomas are not likely to be life-threatening, but they do have the potential to cause disfigurement of the skin tissue.

Almost one million new cases of basal cell carcinoma are diagnosed each year in the U.S., and up to 30% of Caucasians may develop basal cell carcinomas in their lifetime.

Basal cell carcinoma treatment

Basal cell carcinoma can be treated by removing the affected area.

Skin cancer is considered low risk when the affected cells remain clustered in a single group. Both basal cell carcinoma and squamous cell carcinoma are rarely life-threatening. Though it is unlikely to spread to other parts of your body, if left untreated, basal cell carcinoma can move into nearby bone or other tissue.

Basal cell carcinoma typically begins as a small, shiny bump on the face, although it can occur on any part of the body.

What Is Melanoma?

Melanoma, the deadliest of skin cancers, only accounts for about 4 percent of all skin cancer cases, but causes about 79 percent of skin cancer deaths.

Melanoma is a cancer of the skin that begins in the melanocytes, which are the cells that produce the pigment melanin. It is the leading cause of cancer death in women 25 to 30 years old and the second leading cause of cancer death in women 30 to 35 years old.

In some cases, melanoma occurs in melanocytes throughout the body, even if those parts have never been exposed to the sun.

 

What Is Mohs Surgery?

Mohs surgery offers the highest cure rates for all non-melanoma skin cancers. For certain cases of the most common types of skin cancer — squamous cell carcinoma and basal cell carcinoma — the cure rate can be as high as 99 percent.

Mohs surgery is a highly specialized surgical technique used to treat non-melanoma skin cancers in which the surgeon removes all of the visible cancer, plus a small margin of the surrounding healthy tissue and examines it to ensure that all cancer cells have been removed at the time of surgery.

During Mohs micrographic surgery — named after Dr. Frederic Mohs, who first performed it in the 1930s — cancer is removed from the skin layer by layer until all cancerous cells have been removed. This type of surgery is most commonly used for cancers that have a high risk of re-occurrence. This technique allows for complete removal of the skin cancer while minimizing the removal of surrounding healthy skin.

What Is Skin Cancer?

Skin cancer is the most common form of cancer in the U.S. with more than 3.5 million cases diagnosed each year.

Skin cancer is the result of uncontrolled growth of abnormal skin cells that takes place when skin cells suffer DNA damage and then mutate, causing them to multiply rapidly and form malignant (cancerous) tumors. Most skin cancers develop on the visible outer layer of the skin (the epidermis), particularly on sun-exposed areas such as the face, head, hands, arms and legs. They are usually easy to detect with a skin examination, which increases the chances of early diagnosis.

There are different types of skin cancer, each named for the type of skin cell from which they originate. The most common type of skin cancer is basal cell carcinoma. Almost one million new cases of basal cell carcinoma are diagnosed each year in the U.S. Most skin cancers fall into one of three categories:

There are often warning signs that cancer is developing. The most common are pre-cancerous lesions called actinic keratoses that often develop on sun-exposed areas. These tumors replace normal surrounding tissue and generally do not spread to other areas.

Skin cancer is considered low risk when the affected cells remain clustered in a single group. Both basal cell carcinoma and squamous cell carcinoma are rarely life-threatening.

Skin cancer is considered a high risk when cells have invaded surrounding tissues. The third most common skin cancer, malignant melanoma, can be life-threatening if not diagnosed and treated early.

If skin cancer is detected before it has spread to surrounding tissues, the chances of a complete recovery and cure are excellent. High-risk forms of cancer like melanoma require more aggressive treatments.

What Is Squamous Cell Carcinoma?

Squamous Cell Carcinoma is a common form of skin cancer that develops in the squamous cells that make up the outer layer of the skin. Although it is usually not life-threatening, it can be aggressive in some cases.

If left untreated, squamous cell carcinoma can grow large or spread to other parts of your body, causing serious complications.

What Is Cryotherapy?

Cryotherapy, or “cryosurgery,” is a simple, non-invasive procedure in which liquid nitrogen is used to freeze and destroy growths on the surface of the skin. This is an effective treatment for precancerous skin lesions (actinic keratoses), as well as other skin conditions such as warts, skin tags and moles.

Applying liquid nitrogen to skin lesions allows dermatologists to target the damaged skin cells and destroy them at the cellular level. After freezing, the affected area may blister and scab over, and should heal within three to six weeks.

Our dermatology team uses cryosurgery to treat a wide range of conditions. It offers a number of advantages: Cryotherapy is a simple, affordable outpatient procedure, the discomfort level is minimal, and there is a low risk of infection.

What Are Skin Cysts?

Cysts are pockets of tissue (sacs) that may become filled with pus, fluids, skin cells, and even air.

They are fairly common on the skin and can appear anywhere on the body. Cysts may feel like a pea under the surface of the skin, but without removal, they can grow significantly larger over time. In most cases, cysts are not painful, and they grow slowly. There are different types of cysts as we’ll discuss in the next section, and the vast majority of these skin growths are benign (not cancerous). Not all cysts will require treatment, but it is vitally important to have any lump under the skin evaluated and diagnosed by a board-certified dermatologist because some soft tissue malignancies (growths that are cancerous) can present like a cyst. Before recommending removal or other cyst treatments, your dermatologist will examine the growth to determine whether it is likely to cause you pain, become infected, or otherwise lead to skin health issues.

What Are Moles?

Atypical moles, also known as dysplastic nevi, are unusual-looking benign (noncancerous) moles.

A dysplastic mole is one that, when viewed on a cellular level, has features unlike those of a healthy, benign mole. A benign mole will have a regular pattern of coloration and pigment, even borders, symmetry, and a tan or pink color. Dysplastic moles can be asymmetric, have indistinct borders, or contain multiple colors or very dark pigment.

Dysplastic moles are often spotted as the “ugly duckling” on a patient’s skin. Any departure from the typical mole a person’s skin makes may be dysplastic. They can appear anywhere on the body, but in most cases are found on the back, chest, buttocks, breasts, or scalp.

People with atypical moles are at a higher risk of developing melanoma.

What Are Keloids?

Keloids are raised, red scars created by excessive healing of skin wounds, such as burns, cuts and acne. They are the result of an overproduction of collagen as the skin tries to repair itself. Keloids also can occur after piercings, tattoos or surgery and often times are itchy and painful. They can grow for years and sometimes show up three months or longer after the injury occurred.

What Is Keratosis Pilaris?

Keratosis pilaris is a common skin condition characterized by small, hard bumps that may make your skin feel like sandpaper. Most often they appear on your upper arms, thighs and buttocks, and sometimes are accompanied by redness or swelling. In some cases they may appear on your face.

It is caused by a buildup of keratin, a protein that protects skin from infections. When a buildup forms, it blocks the opening of a hair follicle and creates the bumps, but doctors don’t know what triggers the buildup.

What Are Skin Tags?

Skin tags are small, soft skin growths that can occur anywhere on the body but are most common on the eyelids, neck, armpits, groin folds and under the breasts. They are harmless but they can be annoying, particularly if they are in an area where they are rubbed on by clothing. They may be flesh-colored, pink or may darken.

What Is Sun Damage?

The sun can age and burn your skin, and it can also cause damage on the cellular level, leading to skin cancer. The good news is, the U.S. Dermatology Partners team can help you formulate a plan to prevent sun damage and repair the effects of the sun’s UV rays so that you can go out and enjoy a sunny day.

What Is Vitiligo?

Vitiligo is an autoimmune disease in which white patches of skin appear on different areas of the body. This happens when melanocytes, the cells that make pigment in the skin, are destroyed. In addition to the skin, it can affect the mucous membranes of the mouth and nose as well as the eyes. Its cause is not known.

What Are Warts?

Warts are benign, non-cancerous growths that appear on the skin as the result of a virus called human papillomavirus, or HPV. They are contagious and are spread by contact – either with the wart or something that touched the wart. Cut or damaged skin is more vulnerable to warts.
