Medical Dermatology at UDA


At United Dermatology Associates we provide comprehensive dermatology services for all patients. We treat all ages and skin types, and we will evaluate any of your dermatologic concerns that pertain to diseases of the skin, hair, or nails.

Sensus Superficial Radiation Therapy (SRT)

By delivering a precise, calibrated dose of Superficial Radiation Therapy that only goes skin deep, patients can be safely treated right here at United Dermatology Associates. Each treatment takes only a few minutes and is virtually painless.

Low-dose radiation effectively destroys basal cell carcinoma and squamous cell carcinoma, as well as the non-malignant tumor cells that cause keloids. Best of all, it doesn’t involve cutting, bleeding or stitching. With the SRT-100™, there is no need for anesthesia, no risk of infection or scarring, no need for reconstructive plastic surgery. Patients heal quickly and don’t have downtime or lifestyle restrictions following treatment.

Sensus Healthcare’s SRT-100™ has been cleared by the U.S. Food and Drug Administration for the treatment of non-melanoma skin cancer and keloids. It is ideal for private dermatology and oncology practices, as well as hospitals and multi-locale healthcare providers.

Photodynamic Therapy (PDT) with Blue Light

This treatment is FDA approved for the treatment of actinic keratoses– precancerous lesions on the skin from sun damage that can develop into skin cancer if left untreated. It involves the application of Levulan (aminolevulinic acid 20%) to affected skin and allowing it to incubate for 45 minutes to an hour. The solution is absorbed by the precancerous cells, where it is converted to a chemical that makes the cells extremely sensitive to light. The skin is then exposed to the BLU-U Blue Light Illuminator, and a reaction occurs which destroys the precancerous cells without damaging normal skin. This is a great treatment option for individuals with significant sun damage. It is a simple, quick, in office procedure. It causes a sunburn-like reaction on the skin that resolves within one week. It is very effective in treating the precancerous lesions, but patients also enjoy the cosmetic response, as the majority of patients treated report a significant improvement in the look and feel of their skin. Patients treated with Levulan should avoid exposure to sun for 48 hours post procedure.

Conditions We Treat

Some of the most common conditions that we evaluate and treat include the following:

Acne is a general term used for acneiform eruptions. It is usually used as a synonym for acne vulgaris. Acne vulgaris (or acne) is a common human skin disease, characterized by areas of skin with seborrhea (scaly red skin), comedones (blackheads and whiteheads), papules (pinheads), pustules (pimples), nodules (large papules) and possibly scarring.

Actinic keratosis also called “solar keratosis” and “senile keratosis” is a premalignant condition of thick, scaly, or crusty patches of skin. It is more common in fair-skinned people. It is associated with those who are frequently exposed to the sun, as it is usually accompanied by solar damage. Since some of these pre-cancers progress to squamous cell carcinoma, they should be treated. Untreated lesions have up to 20% risk of progression to squamous cell carcinoma

Cellulitisis a diffuse inflammation of connective tissue with severe inflammation of dermal and subcutaneous layers of the skin. Cellulitis can be caused by normal skin flora or by exogenous bacteria, and often occurs where the skin has previously been broken: cracks in the skin, cuts, blisters, burns, insect bites, surgical wounds, intravenous drug injection or sites of intravenous catheter insertion. Skin on the face or lower legs is most commonly affected by this infection, though cellulitis can occur on any part of the body. The mainstay of therapy remains treatment with appropriate antibiotics, and recovery periods last from 48 hours to six months.

A cyst is a closed sac, having a distinct membrane and division on the nearby tissue. It may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst could go away on its own or may have to be removed through surgery.

Dandruff is the shedding of dead skin cells from the scalp (not to be confused with a dry scalp). Dandruff is sometimes caused by frequent exposure to extreme heat and cold. As it is normal for skin cells to die and flake off, a small amount of flaking is normal and common; Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking, which can also be accompanied by redness and irritation Dermatitis => Dermatitisis inflammation of the skin (i.e. rash)

The term eczema is broadly applied to a range of persistent skin conditions. These include dryness and recurring skin rashes that are characterized by one or more of these symptoms: redness, skin edema (swelling), itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding. Areas of temporary skin discoloration may appear and are sometimes due to healed injuries. Scratching open a healing lesion may result in scarring and may enlarge the rash.

Fungal infection or Mycosis (plural: Mycoses) is a condition in which fungi pass the resistance barriers of the human or animal body and establish infections. Mycoses can result when the climate is hot and humid, and when people live in crowded conditions. Some fungi reproduce through tiny spores in the air. People inhale those spores or they land on the skin. Therefore, fungal infections often start in the lungs or on the skin

There are many conditions of or affecting the human integumentary system—the organ system that comprises the entire surface of the body and includes skin, hair, nails, and related muscle and glands

Alopecia means loss of hair from the head or body. Alopecia includes baldness, a term generally reserved for pattern alopecia or androgenic alopecia. Compulsive pulling of hair (trichotillomania) can also produce hair loss. This condition is dubbed “traction alopecia”. Hairstyling routines such as ponytails or braids may also induce hair loss, as can hair relaxer solutions, and hot hair irons. In some cases, alopecia is due to underlying medical conditions, such as iron deficiency

Herpes simplex is a viral disease caused by both Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2). Infection with the herpes virus is categorized into one of several distinct disorders based on the site of infection. Oral herpes, the visible symptoms of which are colloquially called cold sores or fever blisters, infects the face and mouth. Oral herpes is the most common form of infection. Genital herpes, known simply as herpes, is the second most common form of herpes. Other disorders such as herpetic whitlow, herpes gladiatorum, ocular herpes (keratitis), cerebral herpes infection encephalitis, Mollaret’s meningitis, neonatal herpes, and possibly Bell’s palsy are all caused by herpes simplex viruses

Hyperhidrosis is a medical condition in which a person sweats excessively and unpredictably. People with hyperhidrosis may sweat even when the temperature is cool or when they are at rest.

Itch is a sensation that causes the desire or reflex to scratch. Itch has resisted many attempts to classify it as any one type of sensory experience. Modern science has shown that itch has many similarities to pain, and while both are unpleasant sensory experiences, their behavioral response patterns are different. Pain creates a withdrawal reflex while itch leads to a scratch reflex

A keloid is a type of scar, which depending on its maturity, is composed of mainly either type III (early) or type I (late) collagen. It is a result of an overgrowth of granulation tissue (collagen type 3) at the site of a healed skin injury which is then slowly replaced by collagen type 1. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to flesh-coloured or red to dark brown in colour. A keloid scar is benign, non-contagious, and sometimes accompanied by severe itchiness and pain, and changes in texture. In severe cases, it can affect movement of skin.

Melanoma is a malignant tumor of melanocytes. Melanocytes are cells that produce the dark pigment, melanin, which is responsible for the color of skin. They predominantly occur in skin, but are also found in other parts of the body, including the bowel and the eye (see uveal melanoma). Melanoma can occur in any part of the body that contains melanocytes.

Melasma (also known as “Chloasma faciei” or the mask of pregnancy when present in pregnant women) is a tan or dark skin discoloration. Although it can affect anyone, melasma is particularly common in women, especially pregnant women and those who are taking oral or patch contraceptives or hormone replacement therapy (HRT) medications.

Nail diseases are distinct from diseases of the skin. Although nails are a skin appendage, they have their own signs and symptoms which may relate to other medical conditions. Nail conditions that show signs of infection or inflammation require medical assistance and cannot be treated at a beauty parlor. Deformity or disease of the nails may be referred to as onychosis.

Nevus is the medical term for sharply-circumscribed and chronic lesions of the skin. These lesions are commonly named birthmarks and moles.

Perioral dermatitis, a condition related to acne vulgaris, consists of red papules that may appear microvesicular that typically affect the nasolabial folds (around the nostrils), perioral area (around the mouth) or perioccular area (around the eyes). It usually affects women between the ages of 20 and 45. It is not uncommon, and has a tendency to recur in individuals who have had it once

A wart is generally a small, rough growth, typically on hands and feet but often other locations, that can resemble a cauliflower or a solid blister. They are caused by a viral infection, specifically by human papillomavirus 2 and 7. There are as many as 10 varieties of warts, the most common considered to be mostly harmless. It is possible to get warts from others; they are contagious and usually enter the body in an area of broken skin. They typically disappear after a few months but can last for years and can recur.

Human skin color is primarily due to the presence of melanin in the skin. Skin color ranges from almost black to white with a pinkish tinge due to blood vessels underneath. Variation in natural skin color is mainly due to genetics, although the evolutionary causes are not completely certain. According to scientific studies, natural human skin color diversity is highest in Sub-Saharan African populations, with skin reflectance values ranging from 19 to 46 compared with European and East Asian populations which have skin reflectance values of 62 to 69 and 50 to 59 respectively

Psoriasis is a chronic immune-mediated disease that appears on the skin. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious. There are five types of psoriasis: plaque, guttate, inverse, pustular and erythrodermic. The most common form, plaque psoriasis, is commonly seen as red and white hues of scaly patches appearing on the top first layer of the epidermis (skin). Some patients, though, have no dermatological symptoms.In plaque psoriasis, skin rapidly accumulates at these sites, which gives it a silvery-white appearance. Plaques frequently occur on the skin of the elbows and knees, but can affect any area, including the scalp, palms of hands and soles of feet, and genitals. In contrast to eczema, psoriasis is more likely to be found on the outer side of the joint.

Breaking out (eruption) of the skin. A rash can be caused by an underlying medical condition, hormonal cycles, allergies, or contact with irritating substances. Treatment depends on the underlying cause of the rash. Medically, a rash is referred to as an exanthem.

Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term “ringworm” is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails

Rosacea is a chronic condition characterized by facial erythema (redness). Pimples are sometimes included as part of the definition. Unless it affects the eyes, it is typically a harmless cosmetic condition. Treatment in the form of topical steroids can aggravate the condition. It primarily affects Caucasians of mainly northwestern European descent and has been nicknamed the ‘curse of the Celts’ by some in Britain and Ireland, but can also affect people of other ethnicities. Rosacea affects both sexes, but is almost three times more common in women. It has a peak age of onset between 30 and 60.

A seborrheic keratosis (also known as “Seborrheic verruca,” and “Senile wart” is a noncancerous benign skin growth that originates in keratinocytes. Like liver spots, seborrheic keratoses are seen more often as people age. In fact they are sometimes humorously referred to as the “barnacles of old age”.

Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso. Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso.

Skin neoplasms are skin growths with differing causes and varying degrees of malignancy. The three most common malignant skin cancers are basal cell cancer, squamous cell cancer, and melanoma, each of which is named after the type of skin cell from which it arises. Skin cancer generally develops in the epidermis (the outermost layer of skin), so a tumor can usually be seen. This means that it is often possible to detect skin cancers at an early stage. Unlike many other cancers, including those originating in the lung, pancreas, and stomach, only a small minority of those affected will actually die of the disease, though it can be disfiguring. Melanoma survival rates are poorer than for non-melanoma skin cancer, although when melanoma is diagnosed at an early stage, treatment is easier and more people survive

Dermatitis is inflammation of the skin (i.e. rash).

An acrochordon, also known as a (cutaneous) skin tag, or fibroepithelial polyp, is a small benign tumour that forms primarily in areas where the skin forms creases, such as the neck, armpit, and groin. They may also occur on the face, usually on the eyelids. Acrochorda are harmless and typically painless, and do not grow or change over time.Though tags up to a half-inch long have been seen, they are typically the size of a grain of rice. The surface of an acrochordon may be smooth or irregular in appearance and is often raised from the surface of the skin on a fleshy stalk called a peduncle. Microscopically, an acrochordon consists of a fibro-vascular core, sometimes also with fat cells, covered by an unremarkable epidermis. However, tags may become irritated by shaving, clothing or jewelry.

Squamous cell carcinoma (SCC or SqCC), occasionally rendered as “squamous-cell carcinoma”, is a histologically-distinct form of cancer. It arises from the uncontrolled multiplication of transformed malignant cells showing squamous differentiation and tissue architecture. Squamous cell carcinoma is one of the most common cancers, and frequently forms in a large number of body tissues and organs, including skin, lips, mouth, esophagus, urinary bladder, prostate, lung, vagina, and cervix, among others. Despite the common name, squamous cell carcinomas often show large differences, depending on where they develop, in their presentation, natural history, prognosis, and response to treatment

A sunburn is a burn to living tissue, such as skin, which is produced by overexposure to ultraviolet (UV) radiation, commonly from the sun’s rays. Usual mild symptoms in humans and other animals include red or reddish skin that is hot to the touch, general fatigue, and mild dizziness. An excess of UV radiation can be life-threatening in extreme cases. Exposure of the skin to lesser amounts of UV radiation will often produce a suntan. Excessive UV radiation is the leading cause of primarily non-malignant skin tumors.

Tinea versicolor (also known as “Dermatomycosis furfuracea”, “Pityriasis versicolor” and “Tinea flava”) is a condition characterized by a rash on the trunk and proximal extremities. Recent research has shown that the majority of pityriasis versicolor is caused by Malassezia globosa, although M. furfur is responsible for a small number of cases. These yeasts are normally found on the human skin and only become troublesome under certain circumstances, such as a warm and humid environment, although the exact conditions that cause initiation of the disease process are poorly understood.

Onychomycosis or nail fungus is a common condition that begins as a white or yellow spot under the tip of your fingernail or toenail. As the fungal infection goes deeper, nail fungus may cause your nail to discolor, thicken and crumble at the edge. It can affect several nails but usually not all of them.

Vitiligo is a disorder that causes depigmentation of patches of skin. It occurs when melanocytes, the cells responsible for skin pigmentation, die or are unable to function. The cause of vitiligo is unknown, but research suggests that it may arise from autoimmune, genetic, oxidative stress, neural, or viral causes. The incidence worldwide is less than 1%. The most common form is non-segmental vitiligo.
