PREDOMINANTLY PERIVASCULAR DERMATITIS Superficial perivascular dermatitis Pigmented purpuric dermatoses Pigmented purpuric dermatoses (PPDs) comprise asymptomatic to mildly pruritic pigmented lesions, with distinct clinical and histological findings.6 Although the aetiopathogenesis is unknown, ster-oids, antihistaminics, griseofulvin The histopathologic findings from the active border may show a vacuolar degeneration of the basal cell layer, occasional colloidal bodies, pigment incontinence, phagocytic cells, congestive and dilated vessels, and a perivascular inflammatory lymphohistiocytic infiltrate. 1-4 Fibrosis has not been reported as a histological feature for the diagnosis of ashy dermatosis. Perivascular lymphocytic dermatitis is an inflammation in the skin which has been infiltrated by lymphocytes, a type of white blood cells. There isn’t much difference between perivascular dermatitis and other types of dermatitis really; it’s just that this one occurs near the blood vessels, caused by irritation to the skin or allergens. 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 … Differential diagnosis of interstitial granulomatous dermatitis. Leucocytoclastic vasculitis: Neutrophils and dust in interstitial granulomatous dermatitis are more widely distributed throughout the dermis in addition to around vessels.

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. 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 ].

To the Editor: Erythema dyschromicum perstans or ashy dermatosis is a chronic hyperpigmentary disease of unknown etiology. 1 It presents as ash-colored usually asymptomatic macules located in trunk and proximal extremities. Histopathological findings demonstrate lichenoid dermatitis with vacuolization of basal cells, colloid bodies, and a moderate infiltrate of lymphocytes in the papillary

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

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 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. A pattern of subacute, chronic dermatitis or acute dermatitis may be seen. The dermal inflammatory infiltrate predominately contains lymphocytes and other mononuclear cells (figure 7).

Luz Fonacier, Mark Boguniewicz, in Pediatric Allergy: Principles and Practice (Third Edition), 2016. Spectrum of Contact Dermatitis. Contact dermatitis is traditionally divided into ICD, accounting for 80%, and ACD, accounting for 20% of these reactions. However, there are other diseases that are caused by an external inciting factor such as contact urticaria (CU) and protein contact

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.

The use of the phrase "d … Histopathologically, the majority of inflammatory skin diseases exhibit the basic pattern of perivascular dermatitis as described by Ackermann. With respect to the epidermis, the finding of interface dermatitis constitutes a key criterion for the classification of perivascular inflammatory patterns.
