In simple words: Sweet's syndrome is a skin disease that causes painful, red, swollen bumps on the skin, often accompanied by fever and general feeling of illness. It's usually treated with medicine to reduce inflammation.
L98.2, Febrile neutrophilic dermatosis [Sweet], is an acute, febrile, neutrophilic dermatosis characterized by the sudden onset of painful, erythematous, edematous papules and plaques.These lesions are typically located on the face, neck, and upper extremities, and may be accompanied by systemic symptoms such as fever, malaise, and arthralgia.The condition is believed to be associated with underlying inflammatory conditions, malignancies, or medications.Histopathological examination reveals a dense infiltrate of neutrophils in the dermis. Treatment is typically with corticosteroids or other immunosuppressants.
Example 1: A 45-year-old female presents with sudden onset of painful, erythematous papules and plaques on her face and neck, accompanied by fever and malaise.A skin biopsy reveals a dense neutrophilic infiltrate, consistent with Sweet's syndrome.She is treated with oral corticosteroids, resulting in resolution of her symptoms., A 62-year-old male with a history of acute myeloid leukemia develops painful, raised lesions on his arms and legs.Laboratory findings support the diagnosis of Sweet's syndrome secondary to his underlying malignancy.He receives systemic corticosteroids and supportive care., A 30-year-old female presents with a similar skin presentation, triggered by a newly prescribed medication.After medication discontinuation, her symptoms resolve. This highlights the importance of considering drug reactions in the differential diagnosis of Sweet's syndrome.
Detailed clinical history including onset, duration, location, and characteristics of the lesions; systemic symptoms such as fever, malaise, and arthralgia; relevant laboratory results, including complete blood count (CBC) with differential; results of skin biopsy with histopathological examination;documentation of treatment and response to therapy.
** Sweet's syndrome can be associated with various underlying conditions and medications.Accurate diagnosis requires a thorough clinical evaluation and potentially further investigations.
