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 ...
Rarely eosinophils [1] Allergic drug reaction Rarely involvement of hair follicles. [1] Frequently eosinophils [1] Lichen sclerosus: Hyperkeratosis, atrophic epidermis, sclerosis of dermis and dermal lymphocytes. [2] Erythema multiforme Lupus erythematosis Typical findings in systemic lupus erythematosus: [3] Fibrinoid necrosis at the ...
Typically a superficial and deep perivascular lymphocytic infiltrate. [22] Plasma cells are typically located at the periphery of the lesion, whereas eosinophils are in the center. [22] Kaposi’s sarcoma in patch stage The patch stage typically shows irregular proliferation of jagged vascular channels in the dermis below an integral epidermis.
Eosinophilic dermatosis is a form of dermatosis characterized by a preponderance of eosinophils in the dermis or epidermis. [1] Although it does not always imply a specific etiology, it is still commonly used as a classification in dermatology when more information about the condition is not known.
Skin biopsy of the affected areas may show an increased number of eosinophils. [2] Other conditions that may appear similar include cellulitis, contact dermatitis, and severe allergic reactions such as anaphylaxis. [2] Treatment is often with a corticosteroids. [2] Steroids applied as a cream is generally recommended over the use of steroids by ...
The dermis contains two vascular networks that run parallel to the skin surface—one superficial and one deep plexus—which are connected by vertical communicating vessels. [8] [11] The function of blood vessels within the dermis is fourfold: to supply nutrition, to regulate temperature, to modulate inflammation, and to participate in wound ...
Based on their causes, hypereosinophilias can be sorted into subtypes. However, cases of eosinophilia, which exhibit eosinophil counts between 500 and 1,500/μL, may fit the clinical criteria for, and thus be regarded as falling into, one of these hypereosinophilia categories: the cutoff of 1,500/μL between hypereosinophilia and eosinophilia is somewhat arbitrary.
The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
