Sweet's syndrome : Causes-Symptoms-Diagnosis-Treatment
What Is Sweet's Syndrome?
Sweet's syndrome (the eponym for acute febrile neutrophilic dermatosis) is characterized by means of a constellation of clinical signs and symptoms, bodily capabilities, and pathologic findings which consist of fever, neutrophilia, smooth erythematous pores and skin lesions (papules, nodules, and plaques), and a diffuse infiltrate consisting predominantly of mature neutrophils that are commonly placed in the upper dermis. Several instances of Sweet's syndrome have been published. Sweet's syndrome is offered in three medical settings: classical (or idiopathic), malignancy-related, and drug-induced. Classical Sweet's syndrome (CSS) commonly occurs in women between the age of 30 to 50 years, it is regularly preceded by a higher respiration tract contamination and may be related to inflammatory bowel sickness and being pregnant. Approximately one-1/3 of patients with CSS experience recurrence of the dermatosis. The malignancy-related Sweet's syndrome (MASS) can occur as a paraneoplastic syndrome in patients with an established cancer or people whose Sweet's syndrome-associated hematologic dyscrasia or solid tumor became formerly undiscovered; MASS is most usually related to acute myelogenous leukemia. The dermatosis can precede, comply with, or appear concurrent with the prognosis of the patient's cancer. Hence, MASS may be the cutaneous harbinger of both an undiagnosed visceral malignancy in a previously cancer-free individual or an unsuspected cancer recurrence in an oncology patient. Drug-brought about Sweet's syndrome (DISS) maximum usually takes place in sufferers who have been handled with granulocyte-colony stimulating aspect, however, other medications can also be associated with DISS.
Medical terms
Sweet's syndrome, also known as acute febrile neutrophilic dermatosis, is a rare and inflammatory skin condition characterized by the sudden onset of fever, painful skin lesions, and an increase in white blood cells (neutrophils) in the blood. It was first described by Dr. Robert Douglas Sweet in 1964.
Key features of Sweet's syndrome include:
Skin Lesions: Sweet's syndrome typically presents with raised, painful, and red skin lesions that can vary in size. These lesions often appear on the arms, neck, face, or other parts of the body.
Fever: Patients with Sweet's syndrome usually have a high fever, which can be one of the first symptoms to appear.
Neutrophilic Infiltration: Biopsy of the skin lesions often reveals a dense infiltration of neutrophils in the upper layer of the skin (the dermis).
Associated Conditions: Sweet's syndrome can occur as an isolated condition or be associated with other underlying medical conditions, such as infections, inflammatory bowel disease, autoimmune disorders (e.g., rheumatoid arthritis), and certain malignancies (e.g., leukemia).
Rapid Onset: Symptoms of Sweet's syndrome often develop rapidly over a period of a few days to weeks.
The exact cause of Sweet's syndrome is not well understood, but it is thought to be related to an abnormal immune response. It can affect people of all ages and both sexes, although it is more commonly diagnosed in women. Diagnosis is typically based on clinical symptoms, skin biopsy findings, and ruling out other potential causes of similar symptoms.

Injury where the rash is, like a needle prick or insect bite
Pregnancy
