What is Lichenoid interface dermatitis?
What is Lichenoid interface dermatitis?
The terms ‘lichenoid’ and ‘interface’ dermatitis are often used interchangeably to describe an inflammatory pattern characterized histologically by damage to the basal keratinocytes in the epidermis. The mechanism of cell damage of such cells is now best understood as apoptosis, or programmed cell death.
What causes vacuolar interface dermatitis?
An interface dermatitis with vacuolar alteration, not otherwise specified, may be caused by viral exanthems, phototoxic dermatitis, acute radiation dermatitis, erythema dyschromicum perstans, lupus erythematosus and dermatomyositis.
Which is the primary pathology of interface dermatitis?
Interface dermatitis. Interface dermatitis includes diseases in which the primary pathology involves the dermo-epidermal junction. The salient histological findings include basal cell vacuolization, apoptotic keratinocytes (colloid or Civatte bodies), and obscuring of the dermo-epidermal junction by inflammatory cells. S ….
Can a particle beam be used to destroy a target?
One effective process to cause damage to or destroy a target is to simply overheat it until it is no longer operational. However, after decades of R&D, particle-beam weapons are still very much at the research stage and it remains to be seen if or when they will be deployed as practical, high-performance military weapons.
How does a neutral particle beam weapon work?
A neutral-particle-beam weapon ionizes atoms by either stripping an electron off of each atom, or by allowing each atom to capture an extra electron. The charged particles are then accelerated, and neutralized again by adding or removing electrons afterwards.
What kind of device does a particle beam come from?
The following devices are commonly used as sources for particle beams: cathode ray tube, or more specifically in one of its parts called electron gun. This is also part of traditional television and computer screens.
