Causes of vacuolar interface dermatitis

Main conditions	Characteristics	Micrograph	Photograph
Generally/Not otherwise specified	Typical findings, called "vacuolar interface dermatitis": Mild inflammatory cell infiltrate along the dermoepidermal junction (black arrow in image) Vacuolization within the basal keratinocytes (white arrow in image) Often necrotic, predominantly basal, individual keratinocytes, manifesting as colloid or Civatte bodies
Acute graft-versus-host-disease	Vacuolar alteration of various severity, from focal or diffuse vacuolation of the basal keratinocytes (grade I), to separation at the dermoepidermal junction (grade III) Involvement of the hair follicle Rarely eosinophils
Allergic drug reaction	Rarely involvement of hair follicles. Frequently eosinophils
Lichen sclerosus	Hyperkeratosis, atrophic epidermis, sclerosis of dermis and dermal lymphocytes.
Erythema multiforme
Lupus erythematosis	Typical findings in systemic lupus erythematosus: Fibrinoid necrosis at the dermoepidermal junction Liquefactive degeneration and atrophy of the epidermis Mucin deposition in the reticular dermis Edema, small hemorrhages Mild and mainly lymphocytic infiltrate in the upper dermis Fibrinoid material in the dermis around capillary blood vessels, on collagen and in the interstitium In non-bullous cases, perivascular and interstitial neutrophils are sometimes present in the upper dermis, with damage to blood vessels	File:Histopathology of systemic lupus erythematosus.jpg	File:Butterfly rash of lupus erythematosus.jpg
