Vacuolar interface dermatitis is a dermatitis with vacuolization at the dermoepidermal junction, with lymphocytic inflammation at the epidermis and dermis.[1]

Mainly dermatitis
Microscopic evaluation
Look for characteristic findings among the causes of vacuolar interface dermatitis:
Main conditions[2] | Characteristics | Micrograph | Photograph | |
---|---|---|---|---|
Generally/Not otherwise specified | Typical findings, called "vacuolar interface dermatitis":[2]
|
|||
Acute graft-versus-host-disease | ||||
Allergic drug reaction | ||||
Lichen sclerosus | Hyperkeratosis, atrophic epidermis, sclerosis of dermis and dermal lymphocytes.[3] | |||
Erythema multiforme | ||||
Lupus erythematosis | Typical findings in systemic lupus erythematosus:[4]
|
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.[2]
Unclear cases
PAS-staining showing a thickened basement membrane indicates mainly systemic lupus erythematosus or dermatomyositis, but also possibly lichen sclerosus.[5]
