The main feature of chronic allergic CD is epidermal reaction with lichenification
, fissures, and pruritus (2).
With LS, there is lichenification
, atrophy, and sclerosis.

of antecubital and popliteal fossae is common .
Horses with MEED frequently showed areas of alopecia and exudative dermatitis, with epidermal ulcerations, hyperkeratosis, and lichenification
. The head and lower parts of the legs, especially the coronary bands, are always involved (NIMMO WILKIE et al., 1985; HENSON et al., 2002; BOSSELER et al., 2013; MAULDIN & PETERS-KENNEDY, 2016).
In patients with skin of color, blanching of the skin may be helpful to detect erythema, lichenification
, follicular accentuation, and hypopigmentation (all of which are more common than in lighter-skinned patients).
Cases under study showed erythema, lichenification
, excoriation and alopecia, these lesions were identified as lesions in different parts of body such as pedal dermatitis 100%, facial lesion 90%, ear pinna 100% and ventral abdomen 60%.
The SCORAD index contains 6 items to evaluate AD intensity: erythema, excoriation, oedema or papulation, lichenification
, oozing or crust, and dryness.
The shape of skin lesions was defined as erythema (E), induration/ papulation (I), excoriation (Ex), and lichenification

The Mongoloid skin has a tendency towards lichenification
; they occupy an intermediate position between Caucasoids and Congoids with regards incidence of skin disease.3
