They are often present on the lower trunk and buttocks. These conditions can also present with plaques and nodules. Because of this variable presentation, a skin biopsy is required for confirmation. [worldallergy.org]
The section Cases presents brief case reports that convey clear, practical lessons. Preference is given to common presentations of important rare conditions, and important unusual presentations of common problems. [cmaj.ca]
The patient presented herein exhibited allergic reactions to both luliconazole and lanoconazole. [medicaljournals.se]
Allergic contact dermatitis can present on physical exam as acute or chronic. Acute ACD characteristically presents as an erythematous, eczematous, or vesicular dermatitis. [ncbi.nlm.nih.gov]

- Severe Pain
Contact dermatitis symptoms can range from mild redness and dryness to severe pain and peeling that can be disabling. [my.clevelandclinic.org]
- Military Personnel
Shoe allergic contact dermatitis reportedly occurs in 1.5 to 24 percent of patch-tested patients. 9,10 Men seem predisposed due to their wearing of occlusive footwear for long periods of time (as is the case with factory workers and military personnel [podiatrytoday.com]
Skin
- Blister
Often patients develop lines of small blisters on the skin where the plant brushed against them. [mariettaderm.com]
The dermatitis usually shows redness, swelling and water blisters, from tiny to large. The blisters may break, forming crusts and scales. Untreated, the skin may darken and become leathery and cracked. [aocd.org]
The affected skin may be red and itchy, swollen and blistered, or dry and bumpy. [dermnetnz.org]
Irritant contact dermatitis symptoms include: Mild swelling of skin Stiff, tight feeling skin Dry, cracking skin Blisters Painful ulcers on the skin Symptoms vary depending on the cause of dermatitis. [my.clevelandclinic.org]
Contact dermatitis may appear flat or raised, and in severe cases, blisters filled with clear fluid may result. Although some people react more quickly than others, these rashes tend to take time to develop and don't occur with the first exposure. [yalemedicine.org]
- Photosensitivity
Photosensitivity reactions These are a type of skin allergy in which the causative product causes a reaction only if the skin is concurrently exposed to ultraviolet or other forms of radiation present in sunlight. [news-medical.net]
Phototoxic dermatitis (see Chemical photosensitivity ) is a variant in which topical (eg, perfumes, coal tar) or ingested (eg, psoralens) agents generate damaging free radicals and inflammatory mediators only after absorption of ultraviolet light. [msdmanuals.com]
An individual who uses a cream before bed may never know they are photosensitive to the product because it is absorbed well before contact with the sun. Share on Pinterest A home treatment option for contact dermatitis may be antihistamine drugs. [medicalnewstoday.com]
Some products cause a reaction only when the skin is also exposed to sunlight (photosensitivity). [medlineplus.gov]
A photoallergic reaction may develop when UV light interacts with chemical agents (i.e. fragrances, para-aminobenzoic acid, plants, parsnips, figs, or certain oral medications), inducing various forms of photosensitization. [worldallergy.org]
- Dry Skin
To apply the emollient: use a large amount smooth the emollient into the skin in the same direction that the hair grows do not rub the emollient in for very dry skin, apply the emollient every two to three hours after a bath or shower, gently dry the [hse.ie]
Factors which may hasten the reaction or themselves act as irritants include exposure through wet skin, dry skin, and extreme climatic conditions. [news-medical.net]
The effect is exacerbated in winter by environmental factors (wind, cold) which cause drying of the skin. [hse.gov.uk]
With mild irritants, you may only see small amounts of redness, dry skin, small skin cracks, and/or itching. With stronger irritants, you’re likely to see or swelling, pain, blistering, and oozing of the affected area. [verywellhealth.com]
- Skin Thickening
Symptoms Itching, rash, swelling, blisters, peeling, skin thickening, rhagades. Affected areas Where the skin has come into contact with the allergen that caused the reaction. Unlike ICD, it can spread to the surrounding areas. [unifarcobiomedical.com]
Acute dermatitis presents with erythema (redness) and vesiculation (blistering), and chronic dermatitis with dryness, lichenification (skin thickening) and fissuring (splitting).1 Contact dermatitis refers to these reactions following contact with substances [nursinginpractice.com]
Chronic lesions may manifest as fissuring, skin thickening, lichenification, acneiform eruptions, hypo- or hyper-pigmentation. [worldallergy.org]
- Flushing
DO Flush Your Sinuses Before Bedtime A runny or stuffy nose can make it difficult to fall asleep and stay asleep. A good way to relieve your nighttime symptoms is by clearing out your nasal passages just before you go to bed. [allergyfortworth.com]
Some common side effects of alitretinoin include: headaches dry mouth anaemia (a reduced number of red blood cells) flushed (warm and red) skin increased levels of cholesterol and triglyceride (fatty substances) in the blood joint or muscle pain dry eyes [hse.ie]
Neurologic
- Confusion
Also, there are some common skin conditions, which are confused with dermatitis: psoriasis, pustulosis of the palms and soles, tinea, scabies, lichen planus. [hse.gov.uk]
This confusion often arises during evaluation of weak positive results. Cases of extensive erythema and induration make differentiation between ICD and ACD difficult, particularly in the face of unclear clinical relevance[ 14 ]. [wjgnet.com]

Patients should not simply receive treatment and sent out the door with a prescription. It is crucial to tailor the treatment to the patient, and the body part affected. [ncbi.nlm.nih.gov]
One of the current primary treatments for severe allergic contact dermatitis is the use of corticosteroids. Long-term use of corticosteroids can result in skin atrophy, spider veins, loss of skin color or corticosteroid acne. [sciencedaily.com]
After responding to initial treatment, the patient was discharged with ibuprofen and a tapering dose of oral prednisone from 60 mg 5 times daily, to 40 mg 5 times daily, to 20 mg 5 times daily over 15 days. [mdedge.com]

Prognosis
Prognosis for allergic contact dermatitis is usually worse compared to irritant contact dermatitis unless the allergen is identified and avoided (1). A common cause of this type of dermatitis is nickel. Reference: (1) Rashid RS, Shim TN. [gpnotebook.com]
Prognosis Most cases of contact dermatitis are easily treated and will resolve with time if we avoid the substance that is causing the allergic or irritant reaction. [healthengine.com.au]
Contact allergy to topical medicaments is more common in persons older than 70 years. [15] Prognosis The prognosis depends on how well the affected individual can avoid the offending allergen. [16] Individuals with allergic contact dermatitis may have [emedicine.medscape.com]
The prognosis is very good but scarring can occur. An example would be exposure to wet cement causing a “cement burn”. [wsiat.on.ca]
Prognosis depends on patient education and compliance in avoiding allergens and appropriate skin care. See smartphone apps to check your skin. [dermnetnz.org]
