Common questions about the various types of dermatitis by Parker, Colorado area dermatologist
Dermatitis is an umbrella term for skin inflammation, yet the redness, itching, scaling, or discomfort it creates rarely looks identical from one person to the next. Learning about the types of dermatitis helps you describe your symptoms more clearly, understand possible triggers, and recognize when a dermatologist like Dr. Sang Kim of the Parker, Colorado area should take a closer look.
What is atopic dermatitis?
Atopic dermatitis, often referred to by some as eczema, is a chronic inflammatory condition that leaves the skin dry, itchy, and prone to recurring flares, and it commonly appears in the skin folds such as the elbows and knees. Genetics, immune-system activity, environmental exposures, and a weakened skin barrier all play a role, while treatment often combines gentle skin care, moisturizers, prescription medication, and trigger management.
How does contact dermatitis develop?
Contact dermatitis appears after the skin touches a troublesome substance, although the underlying reaction falls into one of two categories. Irritant contact dermatitis results from direct damage caused by products such as harsh soaps or cleaning chemicals, while allergic contact dermatitis reflects an immune reaction to an ingredient such as nickel, fragrance, preservatives, or poison ivy.
What makes seborrheic dermatitis different from dandruff?
Seborrheic dermatitis affects oil-rich areas, including the scalp, eyebrows, sides of the nose, ears, and chest, where it produces greasy scales, flakes, redness, or itching. Dandruff represents a milder scalp-focused form, while more noticeable inflammation often responds to medicated shampoos, topical antifungal products, or anti-inflammatory treatment selected for the affected area.

What does dyshidrotic dermatitis look and feel like?
Dyshidrotic dermatitis causes clusters of tiny, intensely itchy blisters along the fingers, palms, or soles, and the skin sometimes peels, cracks, or feels sore after the blisters settle. Sweating, stress, frequent moisture exposure, and sensitivities to metals such as nickel or cobalt often contribute to flares, so identifying patterns provides valuable clues.
Why does nummular dermatitis form round patches?
Nummular dermatitis creates circular or oval spots that often look dry, scaly, crusty, or inflamed, which explains why people sometimes mistake these patches for ringworm. Very dry skin, minor injuries, insect bites, and cold weather often precede an outbreak, while a professional examination with a board-certified dermatologist like Dr. Sang Kim distinguishes it from fungal infections, psoriasis, and other similar-looking conditions.
Who develops stasis dermatitis?
Stasis dermatitis usually affects the lower legs when poor circulation allows fluid to collect in the tissues, leading to swelling, itching, scaling, and brownish or reddish discoloration near the ankles. Because untreated circulation problems sometimes contribute to open sores or infection, early dermatologic evaluation and coordinated care address both the irritated skin and its underlying cause.
How does a dermatologist identify the correct type?
Our dermatologist examines the rash pattern, location, texture, timeline, and possible exposures, then uses tools such as patch testing, a skin scraping, or a biopsy when the diagnosis remains uncertain. We encourage you to seek prompt medical attention for rapidly spreading redness, severe pain, warmth, pus, fever, extensive blistering, facial swelling, or involvement around the eyes.
