H Syndrome: A Rare Genodermatosis Imaged With 18F-FDG PET/CT

Area of Science:

• Dermatology
• Medical Imaging
• Genetics

Background:

• H syndrome (OMIM 612391) is an exceptionally rare autosomal recessive genodermatosis.
• It is primarily characterized by extensive and severe skin infiltration.
• Understanding the full extent of the disease is crucial for patient management.

Observation:

• A single case of H syndrome was investigated.
• The imaging modality used was Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (F-FDG PET/CT).
• The F-FDG PET/CT scan provided detailed visualization of the skin infiltration.

Findings:

• F-FDG PET/CT successfully depicted the widespread nature of the skin infiltration in H syndrome.
• The metabolic activity within the infiltrated skin areas was assessable via PET/CT.
• This imaging approach offers a comprehensive view of the disease burden.

Implications:

• F-FDG PET/CT can be a valuable tool for staging and assessing the extent of H syndrome.
• The findings suggest potential applications of PET/CT in evaluating other rare genodermatoses with cutaneous manifestations.
• Further research could explore the role of PET/CT in monitoring treatment response for H syndrome.
