PERIVASCULAR INFILTRATES See DX Path for details of the conditions below Sometimes when you look at a slide the first thing you notice is that there is an infiltrate around vessels which can be superficial or deep or a combination of both.

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 vessels have a regular profile. 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.

Psoriasis literally means a state of itching, derived from Greek. [3] 2019-08-01 2021-03-16 Histology of lichenoid drug eruption, as well as LP, reveals a nonspecific lichenoid interface dermatitis, basal keratinocyte apoptosis, and pigmentary incontinence. 14 Microscopic findings that are more typical of a lichenoid drug eruption include the presence of eosinophils and plasma cells, a deeper perivascular infiltrate, and a higher proportion of necrotic keratinocytes than seen in JPC SYSTEMIC PATHOLOGY.

Acute dermatitis: the typical pattern is that of superficial perivascular lymphocytic spongiotic dermatitis (hematoxylin‐eosin stain [H&E], original magnification x 200) (a). Chronic eczema: in addition, there is irregular acanthosis of the epidermis with hypergranulosis and parakeratosis, which may correspond to ‘psoriasiform dermatitis’ (H&E, x 100).

Contact dermatitis is traditionally divided into ICD, accounting for 80%, and ACD, accounting for 20% of these reactions.

They are characterized by extravasation of 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.

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, histiocy … Perivascular lymphocytic infiltrate. Perivascular lymphocytic infiltrate refers to inflammation centred around the small vessels in the skin. 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 ].
