Editing Dermatitis (section)

===Less common types===
====Dyshidrosis====
[[Dyshidrosis]] (dyshidrotic eczema, pompholyx, vesicular palmoplantar dermatitis) only occurs on palms, soles, and sides of fingers and toes. Tiny opaque bumps called [[Cutaneous conditions#Morphology|vesicle]]s, thickening, and cracks are accompanied by itching, which gets worse at night. A common type of hand eczema, it worsens in warm weather. (ICD-10 L30.1)

====Discoid====
[[nummular dermatitis|Discoid eczema]] (nummular eczema, exudative eczema, microbial eczema) is characterized by round spots of oozing or dry rash, with clear boundaries, often on lower legs. It is usually worse in winter. The cause is unknown, and the condition tends to come and go. (ICD-10 L30.0)

====Venous====
[[stasis dermatitis|Venous eczema]] (gravitational eczema, stasis dermatitis, varicose eczema) occurs in people with impaired circulation, [[varicose veins]], and [[edema]], and is particularly common in the ankle area of people over 50. There is redness, scaling, darkening of the skin, and itching. The disorder predisposes to [[venous ulcer|leg ulcers]]. (ICD-10 I83.1)

====Herpetiformis====
[[Dermatitis herpetiformis]] (Duhring's disease) causes an intensely itchy and typically symmetrical rash on arms, thighs, knees, and back. It is directly related to [[celiac disease]], can often be put into remission with an appropriate diet, and tends to get worse at night. (ICD-10 L13.0)

====Hyperkeratotic====
Hyperkeratotic hand dermatitis presents with hyperkeratotic, fissure-prone, erythematous areas of the middle or proximal palm, and the volar surfaces of the fingers may also be involved.<ref name="Andrews2005">James, William; Berger, Timothy; Elston, Dirk (2005).

====Neurodermatitis====
[[Neurodermatitis]] ([[lichen simplex chronicus]], localized scratch dermatitis) is an itchy area of thickened, pigmented eczema patch that results from [[habit (psychology)|habitual]] rubbing and scratching. Usually, there is only one spot. Often curable through behaviour modification and anti-inflammatory medication. [[Prurigo nodularis]] is a related disorder showing multiple lumps. (ICD-10 L28.0; L28.1)

====Autoeczematization====
[[Autoeczematization]] (id reaction, auto sensitization) is an eczematous reaction to an infection with [[parasite]]s, [[fungi]], [[bacteria]], or [[virus]]es. It is completely curable with the clearance of the original infection that caused it. The appearance varies depending on the cause. It always occurs some distance away from the original infection. (ICD-10 L30.2)

====Viral====
There are eczemas overlaid by viral infections ([[eczema herpeticum]] or [[eczema vaccinatum|vaccinatum]]), and eczemas resulting from underlying disease (e.g., [[lymphoma]]).

Eczemas originating from ingestion of medications, foods, and chemicals, have not yet been clearly systematized. Other rare eczematous disorders exist in addition to those listed here.
