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.

Perioral dermatitis is a relatively common inflammatory disorder of facial skin, often appearing in patients with rosacea, but with less inflammation. A typical perioral dermatitis presentation occurs with the eruption of papules and pustules confined to the nasolabial folds and the skin of the chin …

HISTORY: This dog had bilaterally symmetrical, rugose thickening, lichenification, and gray-black hyperpigmentation of the axillary skin.

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.

A 71-year-old man expires in a nursing home and an autopsy is performed. At autopsy, he is found to have a strangulated segment of jejunum within an incisional hernia with resulting sepsis. In addition, an enlarged thymus weighing 30 grams is identified. Representative tissue is obtained from the…

It is usually a lymphocytic or lymphohistiocytic inflammatory infiltrate, without evidence of vascular damage/ death (vasculitis). Pigment incontinence The pathologic features of urticarial dermatitis are nonspecific and include a normal stratum corneum, mild epidermal edema with minimal spongiosis, and a superficial to mid-dermal perivascular infiltrate of lymphocytes and eosinophils with occasional neutrophils (picture 1) [ 2 ]. A few basal apoptotic keratinocytes are sometimes present.

The pattern of changes may allow a diagnosis to be made or it may be non-specific. The appearance of many skin diseases vary at different stages of their development and may be altered by attempted treatment and secondary changes such as scratching or infection.

Perivascular dermatitis pathology outlines

DHR is a perivascular lymphocytic dermatitis with eosinophils involving the papillary and upper reticular dermis and minimal, if any, primary epidermal alteration. The term DHR does not represent any known clinical disorder; rather, it corresponds to many clinical disorders. The use of the phrase "d … 38 biopsies of perioral dermatitis have been examined. The following has consistently been observed: follicular hyperkeratosis; vasodilatation and oedema (sometimes very pronounced) of the papillary dermis; perivascular and parafollicular infiltrates consisting predominantly of lymphocytes, histiocytes and polymorphonuclear leucocytes.

Some lesions show nodular collection of blood vessels with perivascular inflammation. The small vessels are thick walled and are lined by plump endothelial cells. There are no atypical features. There is some perivascular fibroblastic proliferation with variable fibroplasia. 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.

Jessner lymphocytic infiltrate plaques usually start off as defined, small, slightly raised red spots that gradually enlarge peripherally to create a well demarcated red plaque. Sometimes the centre of the lesion is left clear, ie forming an annular and arciform shape.
