The reaction most likely to give intraepidermal vesicles is in fact an allergic contact dermatitis, but as I have already said drugs such as thiazide diuretics and calcium channel blockers can also cause spongiotic drug reactions. The eosinophils may infiltrate into the epidermis or they may be mainly perivascular in the dermis.

In the dermis, there is a lichenoid or patchy lymphocytic infiltrate with accen- tuation of the pilosebaceous follicles. Perivascular fibrosis. (onion-skin Antonovych TT (ed) Pathology of systemic lupus erythematosus. Armed Forces

Histology of leukocytoclastic vasculitis. Low power view of leukocytoclastic vasculitis gives the pattern of a busy dermis with a superficial and mid perivascular inflammatory pattern (Figure 1). In non-bullous cases, perivascular and interstitial neutrophils are sometimes present in the upper dermis, with damage to blood vessels 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. Histology of lichenoid drug eruption, as well as LP, reveals a nonspecific lichenoid interface dermatitis, basal keratinocyte apoptosis, and pigmentary incontinence.

Interface dermatitis generally refers to a mild lichenoid-like reaction in the interface between epidermis and dermis. There is sparse scattered lymphocytic infiltration centred around the basal layer +/- vacuolar degeneration of the basal layer.

Less frequently, histopathology revealed the presence of necrotic keratinocytes; surprisingly, only in 2 cases the presence of rare dermal eosinophils was detected, even if all the patients had significant peripheral eosinophilia. 2019-11-08 2020-12-15 2020-10-09 The reaction most likely to give intraepidermal vesicles is in fact an allergic contact dermatitis, but as I have already said drugs such as thiazide diuretics and calcium channel blockers can also cause spongiotic drug reactions.

It is the breakdown of the red blood cells that leaves iron pigment behind that gives both the clinical picture and the histological picture. If you look carefully at the blood vessels in pigmented purpuric eruption, there may be a bit of endothelial cell swelling and some perivascular thickening.

Intradermal mucin. Thin epidermis. Pathological changes may arise in epidermis, dermis and/or subcutaneous tissue. The pattern of changes may allow a diagnosis to be made or it may be non-specific.
