Rashes are a common skin concern, causing discomfort, itchiness, and sometimes even pain. They can appear in various forms, with different causes and treatments. At Kaveri Karhade MD Dermatology, located in San Francisco, CA, we understand the frustration and worry rashes can bring. Our experienced dermatologist, Dr. Kaveri Karhade, can accurately diagnose your rash and create a personalized treatment plan to get your skin healthy again.

Eczema

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition causing dry, itchy, and red patches. This condition is not limited to children; it can affect people of all ages. While the exact cause is unknown, it's often linked to a weakened skin barrier and allergies. Common symptoms include:

  • Dry, itchy skin
  • Red, scaly patches
  • Small bumps that may ooze fluid when scratched
  • Thickened skin

Treatment plans for eczema often involve a combination of approaches, including:

  • Emollients: Moisturizers to hydrate and strengthen the skin barrier
  • Steroid creams: To reduce inflammation and itching
  • Immunosuppressant medications: For more severe cases
  • Light therapy: In some cases, ultraviolet light therapy can be effective

Contact Dermatitis

A rash can appear if your skin touches something that irritates it or triggers an allergy. Irritant contact dermatitis develops from harsh chemicals, soaps, or friction. Allergic contact dermatitis results from an allergic reaction to substances like fragrances, metals, or certain plants.


Symptoms of contact dermatitis typically appear within 48 hours of exposure and can include:

  • Redness
  • Itching
  • Burning sensation
  • Blisters
  • Scaling


Treatment for contact dermatitis focuses on identifying and avoiding the irritant or allergen. We can also prescribe medications like:

  • Corticosteroid creams: To reduce inflammation and itching
  • Calamine lotion: To soothe irritation

Psoriasis

Psoriasis is a chronic autoimmune disease affecting the skin cells' rapid turnover. This leads to thick, red, scaly patches on the skin. While not contagious, psoriasis can be triggered by stress, infections, certain medications, and weather changes. Common symptoms include:

  • Red, raised patches with silvery white scales (plaques)
  • Dry, cracked skin that may bleed
  • Itching or burning sensation
  • Thickened nails

Psoriasis treatment focuses on managing symptoms and slowing skin cell growth. We can tailor a treatment plan to your specific needs, offering a range of options:

  • Topical medications: Creams and ointments containing corticosteroids, retinoids, or vitamin D
  • Light therapy: Ultraviolet light therapy can be effective for moderate to severe psoriasis
  • Oral medications: For more severe cases, medications that suppress the immune system or target specific inflammatory pathways might be prescribed
  • Biologics: Injected medications that target specific aspects of the immune system involved in psoriasis

Seborrheic Dermatitis

Seborrheic dermatitis, often called dandruff when it affects the scalp, is a common inflammatory skin condition causing redness, flakiness, and itchiness. It's thought to be linked to a yeast overgrowth on the skin and can be exacerbated by stress, cold weather, and certain medical conditions. Symptoms typically appear on the scalp, eyebrows, beard area, and chest. These include:

  • Red, scaly patches
  • Greasy or dry flakes
  • Itching


Seborrheic dermatitis treatment often involves over-the-counter antifungal shampoos and creams containing ingredients like ketoconazole, selenium sulfide, or salicylic acid. In some cases, prescription-strength medications might be needed.

Fungal Rashes

Fungal rashes, also known as tinea infections, are caused by various fungi that grow on the skin, hair, or nails. Depending on the location of the infection, different types of fungal rashes exist:

  • Tinea corporis (ringworm): Circular, itchy patches with raised borders, typically on the arms, legs, or torso
  • Tinea cruris (jock itch): Red, itchy rash in the groin area
  • Tinea pedis (athlete's foot): Itching, burning, and scaling between the toes and on the soles of the feet
  • Tinea capitis (scalp ringworm): Patches of scaly, itchy skin with hair loss on the scalp

Diagnosis usually involves a physical examination and sometimes a scraping of the infected area for microscopic analysis. Treatment for fungal rashes typically involves antifungal creams, lotions, or pills, depending on the severity and location of the infection.

Rosacea

Rosacea is a chronic skin condition causing redness, bumps, and visible blood vessels, primarily on the face. The exact cause is unknown, but it's thought to be linked to genetics, sun exposure, and certain triggers like spicy foods, alcohol, and hot beverages. Symptoms typically appear in stages and can include:

  • Facial flushing and redness, especially in the central part of the face
  • Small, red bumps with or without pus
  • Visible blood vessels
  • Burning or stinging sensation
  • Swollen, red bumps on the nose (Rhinophyma) in severe cases


Treatment for rosacea focuses on managing symptoms and preventing flare-ups. We have several treatment approaches available:

  • Topical medications: Creams and gels containing metronidazole, azelaic acid, or ivermectin to reduce inflammation and bumps
  • Oral antibiotics: In some cases, antibiotics can help reduce inflammation
  • Laser treatment: For severe cases, laser therapy can target visible blood vessels
  • Lifestyle modifications: Avoiding triggers, using gentle skincare products, and sun protection are crucial for managing rosacea

Other Rashes

Several other types of rashes can occur, each with its own cause and treatment plan. These include:


  • Heat rash: Red, itchy bumps caused by blocked sweat glands in hot, humid conditions
  • Hives: Raised, itchy welts that appear suddenly and can move around the body. Often caused by allergies, medications, or infections
  • Perioral dermatitis: A red, bumpy rash around the mouth, often triggered by topical medications, cosmetics, or fluoridated toothpasteShingles: A painful, blistering rash caused by the reactivation of the varicella-zoster virus (chickenpox)

Injectable Medications

In some cases, injectable medications might be recommended for treating chronic or severe rashes. These medications can target specific inflammatory pathways or suppress the immune system to manage the underlying cause of the rash.
