differential diagnosis Interstitial Granulomatous Dermatitis or Interstitial Granulomatous Drug Reaction Clinically, PNGD typically presents on extensor surfaces, particularly elbows and fingers whereas interstitial granulomatous dermatitis (IGD)/interstitial granulomatous drug reaction (IGDR), which favor trunk and proximal limbs

Differential diagnosis Otherwise, histological examination is frequently non-specific, with perivascular dermatitis containing eosinophils and neutrophils.

Sometimes the infiltrate is patchy. Urticaria pigmentosa can be a difficult diagnosis to make histologically. You may predominantly see a perivascular infiltrate but when you look closely the cells aren't lymphocytes! They are in fact mast cells. Generally these mast cells are oval in shape, sometimes they can look spindle –like.

Differential diagnoses to consider include infections, skin lymphoma-malignancies, inflammatory dermatoses, nutritional deficiencies, and mechanical causes of tissue damage. We discuss clues to the diagnosis 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. IIIA2 Superficial Perivascular Dermatitis, Mast Cells Predominant. Mast cells are the main infiltrating cells seen in the dermis. and may tend to favor one or another of the possibilities listed in the differential diagnosis tables, the exact classification of these disorders usually depends on clinicopathologic correlation. The histologic differential diagnosis for the spongiotic pattern is broad and requires adequate clinicopathologic correlation.

Therefore, demodicosis should always be on the differential diagnosis list. Parasites other than demodicosis have been reported to cause pododermatitis. These other parasites include hookworm dermatitis, Pelodera dermatitis and tick infestation.

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.

Perivascular dermatitis differential diagnosis

Features: Wedge-shaped perivascular inflammation in the superficial dermis consisting of: Lymphocytes. Eosinophils. Differential diagnosis of a superficial of the recently proposed diagnostic criteria for chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS). Treatment and Monitoring All patients with the diagnosis of CML were lethal and sublethal damage in vascular and perivascular structures, normal tissues, and cells. Arterial stiffness causes a faster reflection of the forward pulse wave the pathogenesis of lymphoma is associated with inflammation [3].

Certainly, the vast majority of biopsies that show the changes described above do not represent chronic superficial dermatitis. Although by no means comprehensive, Table 5-1 provides a differential diagnostic approach to the superficial and the superficial and deep perivascular dermatitides. The reader is referred to other sections of this book for an in-depth consideration of many of these entities. 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 …. Generally in EAC the perivascular infiltrate is quite tightaround the superficial dermal plexus vessels and that is also a good marker for this condition.
