Atypical Histiocyte-Rich Sweet's Syndrome.

Area of Science:

• Dermatology
• Immunology
• Cardiology

Background:

• Sweet's Syndrome is a rare neutrophilic dermatosis linked to immune dysregulation.
• It can be triggered by infections, drugs, pregnancy, or malignancy, or be idiopathic.
• Established diagnostic criteria exist, but systemic involvement varies.

Observation:

• This report details an unusual case of Sweet's Syndrome.
• The patient presented with myopericarditis and acral (extremity) involvement.
• Histological examination revealed atypical findings, notably a predominance of histiocytes.

Findings:

• The case demonstrates a rare association of Sweet's Syndrome with myopericarditis.
• Atypical histological features, including histiocytic predominance, were observed.
• Acral involvement further characterized this unusual presentation.

Implications:

• This case expands the understanding of Sweet's Syndrome's systemic manifestations.
• It underscores the importance of considering cardiac and atypical histological findings in diagnosis.
• Further research may elucidate the role of histiocytes in specific Sweet's Syndrome variants.
