The multiple midget papules that appear are the result of an inflammation is managed by a mathematical group of white stock cells called “ T lymph cell ” . commonly , these blood cells work to bring around diseases or injuries , such as a cut on the finger . MD and research worker do not cognise what causes T lymphocytes to activate in this pathology .
Lichen nitidus is a rare and inveterate inflammatory condition of the skin qualify by the organisation of multiple tiny papules that are referred to as lichenoid rash . It is a benign peel precondition that ordinarily involve shaver of preschool and school old age .
Lichen nitidus lichenoid eruptions often pass off on the surface of the peel in the areas of the flexors of the forearm , back of the hands , chest , abdomen , and private parts . minuscule injury , however , can also go on in the other areas of the body and may require the look .
No mortality or unwholesomeness is being associated with lichen nitidus is generally a benignant disease and does not cause complications .

The disease is prevalent among preschoolers and school day - age children , including young adults , but it can also occur in one-time adults .
Lichen is not a life - threatening disease that resolves on its own without the need for discussion . The incidence is not likely for hide cancer and rarely causes discomfort while being leave without long - last or womb-to-tomb effect on the cutis .
What Causes Lichen Nitidus?
The lawsuit of lichen nitidus disease is unnamed . The lichen nitidus disease is the result of an unusual incendiary activity where T lymphocytes are involved . The relative incidence of lichen nitidus is also being linked to lichen planus , although there has been no clear indication of the relationship between the two .
The exact causal agency of lichen nitidus remains unclear , although several diseases are associated with the incidence of lichen nitidus .
The modest papule of lichen nitidus are fuck as lichen eruption and have various clinical variants such as :
Generalized : Clear lichen seldom occurs in minor and is an even rarer variant .
Hemorrhagic or Lichen Purpuric Nitidus : It is characterize by an unusual rash reduplicate a pigment purpuric papule and ab initio develops on the upper part of the foot and around the ankle before it progresses to the legs until it becomes generalized .
Vesicular : Which are usually located in the ribbon of the bridge player .
Linear Lichen Nitidus : It is a edition that is arranged in the form of a line of business .
Keratodermic : Lichen nitidus involves the decoration of the hand and soles of the ft and looks similar to the crack in inveterate eczema .
Lichen Nitidus Perforated : They are demonstrate by umbilicated papule that normally develop on the forearm and hands .
Actinic : Lichen develops in areas of the skin that are in constant vulnerability to the sun and is common among hoi polloi with dark skin and the eruption of the wound is seasonal commonly during the summer months .
-The size of it of the papule is about 1 mm to 2 millimetre in diam or like to the size of it of a pinhead .
-The soma of the lesion is round to polygonal .
-The color of the papule is skin tone and seldom yellowish or brownish , although it may seem as hypopigmentation or hyperpigmentation in people with dark skin .
-The upper part of the lesion is flat and the lesion appear bright .
-The lesion come along in clusters that can later blend to form a plaque .
-The development of the lesion is usually localize and rarely fall out as generalized .
Lichen nitidus can also explicate in the mouth and the papules are described as small , flat , grey - blank papules that appear within the buccal mucosa . It appears on the tongue as hard white plates and resembles the coming into court of lichen planus .
