A group of skin diseases - includes: The systemic disease, systemic lupus erythematosus, that typically has multi-organ involvement. Microscopic. Features - classic: Lymphocytic interface dermatitis. Basal layer vacuolization. Intradermal mucin. Thin epidermis.

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.

INTEGUMENATRY SYSTEM. August 2019. I-M02 . Signalment (JPC # 21474-17): Dog, breed unspecified HISTORY: This dog presented with pruritus and alopecia that was most severe in the skin of the lower back and base of tail. 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 . ↑Zug, KA.; McKay, M. (Sep 1996).

Lymphocytic vasculitis was present in 17 patients (15.9%), and Langerhans cell microabscess was seen in 4 (3.7%). 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 Background: Psoriasiform dermatitis is a frequently encountered terminology in a wide variety of inflammatory dermatoses. It often poses challenges to both dermatologists and pathologists alike. Background The pigmented purpuric dermatoses are a group of chronic diseases of mostly unknown etiology that have a very distinctive clinical appearance.

Superficial perivascular, predominantly lymphocytic infiltrate with minimal dermal edema. The overlying epidermis has psoriasiform hyperplasia. Notice how the

In allergic/contact dermatitis and atopic dermatitis, eosinophils may be present in the dermis and epidermis (eosinophilic spongiosis). Polymorphic light eruption (PMLE) is a form of photosensitivity, which usually occurs in younger females.It is more common in patients who receive only intermittent sun exposure and typically consists of crops of papules, vesicles or plaques.

Predominantly, a superficial perivascular lymphocytic infiltrate, extravasation of erythrocytes, and focal interface changes characterized DRESS cases. 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. Id reaction (Autoeczematization) •Dissemination of a previously localized ‘eczematous’ process such as fungal infection or stasis dermatitis •Commonly seen as a reaction to foods, look at the feet and nails for fungus. An id reaction is an eczematous skin reaction that develops in response to a distant unknown antigen.

The dermal inflammatory infiltrate predominately contains lymphocytes and other mononuclear cells (figure 7). Allergic contact dermatitis occasionally provokes atypical T-cell infiltrates which may simulate mycosis fungoides. Contact eczema pathology Five major pathological patterns were identified: lichenoid (45/107, 42.1%), perivascular (40/107, 37.4%), interface (11/107, 10.3%), spongiotic (7/107, 6.5%) and granulomatous (4/107, 3.7%). Lymphocytic vasculitis was present in 17 patients (15.9%), and Langerhans cell microabscess was seen in 4 (3.7%). 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).

Seborrheic dermatitis in patients with AIDS may show nonspecific changes, including spotty keratinocytic necrosis, leukoexocytosis, and plasma cells in a superficial perivascular infiltrate . A “papular eruption” may exhibit nonspecific perivascular eosinophils with mild folliculitis, although epithelioid cell granulomas have also been reported ( 6 ).

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 …
