We Treat Most Skin Problems, Including: 


In medical dermatology, a nevus (mole) is a benign cluster of pigment-forming cells. They are congenital (from birth) or acquired. Moles should be considered a normal skin finding, unless there is a history of change, itching, or other symptoms. Symptomatic nevi should be regarded suspiciously and evaluated by a trained dermatologist. A basic rule to follow that can help you determine if a mole is suspicious is “ABCD”: asymmetry, border irregularity, color change or unevenness, and diameter greater than 6mm. Other warning signs to look out for: The appearance of a new bump or nodule, color spreads into surrounding skin, redness or swelling beyond the mole, pain, tenderness, itching, bleeding, oozing, and scaly appearance. If you have any of the above warning signs or are concerned about a mole, contact our office for an appointment. Based on medical dermatology studies, it is important to have your moles evaluated because melanoma, the type of skin cancer that comes from mole cells,  has the best chance of treatment when caught early.


Psoriasis can cause stress and embarrassment to those individuals affected. Psoriasis results when your body produces inflammation and in turn too many skin cells, causing the skin in the affected area to swell and become flaky. Patients with psoriasis often experience red, itchy, and tender skin on the scalp, hands, feet, stomach, knees, and elbows. The cause of psoriasis has not been determined, however, there appears to be a genetic predisposition admixed with environmental factors.  Psoriasis is a chronic condition with no definite cure at this time, however, the skin can be improved and cleared with treatment. Topical medication and changes is diet can sometimes reduce the occurrence of psoriasis, but not in all cases. If conservative treatment fails, combination topical regimens, phototherapy (Excimer laser and Narrow-band UVB available in our office), systemic medications including methotrexate and the newer biologic injectable medications such as Enbrel, Humira, Stelara, and Taltz are available.

Atopic Dermatitis
Atopic Dermatitis

Atopic dermatitis is a chronic, itchy, eczema-like condition of the skin that is usually associated with a personal or family history or asthma, seasonal allergies, or atopic dermatitis. In medical dermatology, there are three forms: infantile, childhood and adulthood. There appears to be a genetic predisposition for atopic dermatitis that can be exacerbated by numerous factors including dry skin, skin infections, irritating clothing or chemicals, change in climate and stress. The treatment of atopic dermatitis includes a good skin care regimen starting with a mild soap, and moisturizing with a cream or ointment base moisturizer to restore the acid mantle of the skin. The mainstay of therapy includes topical steroids, topical nonsteroidal anti-inflammatory cream, and systemic antihistamines. At times severe cases may require systemic therapy. It is important to reduce the itching and inflammation with appropriate use of medication and skin care, to restore the skins natural barrier. New treatments are proving very effective for some patients, including eucrisa ointment.


Acne is the most common disease seen in the field of medical dermatology. It usually begins around adolescents but contrary to popular belief, acne is not confined to teenagers. It may continue until the third or fourth decade of life, in some patients, it does not begin until then. Acne presents as pink-red papules, pustules, nodules or cystic lesions on the face, chest or back. We offer a variety of treatment modalities including topical and oral medications, Blu U® Acne Treatment, chemical peels, and in severe cases isotretinoin (accutane). We also have a certified knowledgeable aesthetician, Annie, who provides aesthetic services such as facials and acne extractions to help your skin achieve maximum improvement.


Rosacea is a common chronic, acne-like condition of the facial skin that affects millions of individuals. It typically appears as flushing or redness on the cheeks, nose, chin or forehead that comes and goes. If left untreated, rosacea tends to worsen over time. As the condition progresses, the redness becomes more persistent, bumps and pimples called papules and pustules appear and small dilated blood vessels may become visible. Rosacea is usually seen in adults. It seems to affect fair-skinned people more often, although it can affect any skin type. Most people who get rosacea have a history of flushing or blushing. Some of the common rosacea symptoms include: redness, pimples, blood vessels, skin thickening, especially the nose, called rhinophyma and eye involvement. Common Rosacea triggers are: hot drinks, caffeine, alcohol, spicy foods, stress, sunlight, extreme heat or cold. Several medications are available by prescription to help control redness and reduce the number of papules and pustules and prevent progression. While topical and oral medications can stop the progression of redness and blood vessels, they are only minimally effective for existing background redness. Blood vessels or telangiectasias are most effectively treated with a laser (Vbeam) that causes selective injury to the blood vessels making them disappear. Home strategies include washing pillow cases often and buying tightly woven fabrics for sheets and pillow cases. 

Skin Cancer
Skin Cancer

Dr. Mehlmauer and Saghari are well practiced in diagnosis and treatment of skin diseases including skin cancer. We will help you understand the cuse of your condition and will explain options for treatment. Dr. Mehlmauer is dual trained in dermatology and dermatopathology. If a skin biopsy reveals that an area of the skin is cancerous we will treat the cancer according to your individual needs. Skin cancers can be treated by cryotherapy, topical immunotherapy, electrodessication and curettage, excision, or through surgical removal using the Mohs technique, which we offer all in our onsite facility.


Melasma is a patchy discoloration (hyperpigmentation) of the face. It is more common in women but can also occur in men. The pigment producing cells in the skin produce extra pigment in response to multiple factors including ultraviolet radiation, genetic predisposition, and hormonal influences. Treatments are individualized based on each patient and their skin type. Sun protection during treatment is essential.

Excessive Sweating
Excessive Sweating

Excessive underarm, hand or foot sweating is called hyperhidrosis. Sweating at unwanted times might result in embarrassment or interference with daily activities. There are ways to control this sweating which include topical solutions, oral medication, iontophoresis, and botox. Sometimes we refer to a surgeon for sympathectomy when appropriate. Contact us for more information.


Warts are caused by the human papilloma virus (HPV). Warts generally occur in healthy children and adults. The virus causes thickening of the skin causing scaling and the classic “warty” appearance. Treatment of warts is directed at destroying the skin cells infected with HPV. In medical dermatology, this may be accomplished with a variety of physical, chemical, or biologic therapies. If you are struggling with a wart that will not go away, contact us for an appointment.

Alopecia (Hair Loss)
Alopecia (Hair Loss)

Hair loss can occur under medically different reasons. Hair loss can be inflammatory, infectious, hereditary, stress or metabolic induced.  Hair loss requires a detailed history, examination, and in some cases laboratory tests and biopsy. If you are experiencing hair loss let our experts in the field of medical dermatology help you determine the cause and find the treatment that’s right for you to stop the loss and help re-growth where possible.

Skin Allergies (Allergic Contact Dermatitis)
Skin Allergies (Allergic Contact Dermatitis)

Skin allergies occur when something comes into contact with the skin, after prior sensitization, causing the skin to become intensely itchy, red, and oozing. The most common example is the classic Poison Ivy/Oak rash that develops after contact with the plant. Other similar type allergic reactions can occur after contact with chemicals in cosmetic products, sunscreens, nickel/other metals, rubber, hair dyes and other substances. If you suspect you may have a skin allergy, it may be frustrating and difficult to find out what exactly is causing the reaction. At Congress dermatology, we offer patch testing, in an effort to find the culprit chemical causing the reaction.  


Vitiligo is a disorder that affects the pigment of the skin and causes white patches to appear on various areas of the body. In the United States it is estimated to occur in almost 1% of the population. The mainstay of therapy for vitiligo includes phototherapy, which helps stabilize spread and regain pigmentation. Other additional treatments which may be combined with phototherapy include topical creams, multivitamin and antioxidant therapy.

Actinic Keratosis
Actinic Keratosis

Actinic keratosis are pre-cancerous lesions that are easily treated by a topical medication, cryotherapy, or light therapy (Photodynamic therapy). Early detection is vital in preventing skin cancers.

Nail Fungus
Nail Fungus

Many patients struggle with abnormal toenails/nails but are reluctant to take an oral medication to treat the condition. Let us explain the latest options in the treatment of nail disease and nail fungus.
