Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, [1] [2] is a skin disease characterized by the sudden onset of fever, an elevated white blood cell count, and tender, red, well-demarcated papules and plaques that show dense infiltrates by neutrophil granulocytes on histologic examination.
Once activated, neutrophils then release preformed substances, including enzymes causing damage to vessel tissue. [9] Evidence of this process can be seen with a sample of removed skin tissue, or biopsy, viewed under a microscope. Neutrophils are seen surrounding blood vessels and their debris within vessel walls, causing fibrinoid necrosis ...
Neutrophils are a type of phagocytic white blood cell and part of innate immunity. More specifically, they form the most abundant type of granulocytes and make up 40% to 70% of all white blood cells in humans. [1] Their functions vary in different animals. [2] They are also known as neutrocytes, heterophils or polymorphonuclear leukocytes.
In NEH, eccrine gland necrosis, and neutrophils surroundings the eccrine glands, are typical findings on biopsy. If the chemotherapy has recently been administered, chemotherapy induced neutropenia may be present, and, as a result, the neutrophils may be absent. But the other characteristic finding, i.e. eccrine gland necrosis, can still be seen.
Neutrophilia (also called neutrophil leukocytosis or occasionally neutrocytosis) is leukocytosis of neutrophils, that is, a high number of neutrophils in the blood. [1] Because neutrophils are the main type of granulocytes , mentions of granulocytosis often overlap in meaning with neutrophilia.
This can occur in many different tissues of the body includes the ears, liver, lung, and skin. The neutrophil warming can also participate in activating pathogen containment, keeping foreign substances localized and easier to treat and rid the body of later on. [12] Figure 1: This figure shows neutrophil swarming starts and stops. [12]
Essentially, toasted skin syndrome can happen anywhere that skin is exposed to heat. "The typical location of the discoloration is the back of heating pads and the anterior thighs from a laptop ...
Reactive neutrophilic dermatoses are a spectrum of conditions mediated by neutrophils, and typically associated with underlying diseases, such as inflammatory bowel disease and hematologic malignancy. [1]: 144 Conditions considered to be reactive neutrophilic dermatoses include: [1]: 144–9 Erythema nodosum; Marshall syndrome
