Chronic, recurrent neutrophilic dermatosis: a case report

Area of Science:

• Dermatology
• Immunology
• Internal Medicine

Background:

• Sweet syndrome is an acute febrile neutrophilic dermatosis.
• It is a reactive condition often associated with systemic illnesses like infections, inflammatory bowel disease, medications, or malignancies.
• Typical presentation involves painful papules, plaques, pustules, or vesicles with constitutional symptoms.

Observation:

• This report details a unique case of chronic, recurrent Sweet syndrome.
• The condition persisted in the patient for over 15 years.
• No underlying systemic illness was identified as the cause.

Findings:

• The case demonstrates a prolonged and relapsing course of Sweet syndrome.
• The absence of a discernible underlying etiology in this chronic case is noteworthy.
• This presentation challenges the typical understanding of Sweet syndrome's triggers and duration.

Implications:

• This case expands the clinical spectrum of Sweet syndrome.
• It suggests that chronic, idiopathic presentations of Sweet syndrome are possible.
• Further research may be needed to understand the mechanisms behind idiopathic chronic Sweet syndrome.
