Insights

Digital necrosis is a medical emergency with diverse causes, often linked to connective tissue diseases in women and varied arterial or local issues in men. This study excluded Progressive Systemic Sclerosis to explore other etiologies.

Area of Science:

  • Vascular Medicine
  • Rheumatology
  • Internal Medicine

Context:

  • Digital necrosis, a critical condition, presents diverse etiologies.
  • Progressive Systemic Sclerosis (PSS) is a common cause in women, necessitating exclusion for broader etiological investigation.
  • Understanding non-PSS causes is crucial for accurate diagnosis and management.

Purpose:

  • To retrospectively identify and categorize the causes of digital necrosis in patients without Progressive Systemic Sclerosis.
  • To analyze the etiological spectrum of digital necrosis in a cohort excluding PSS.
  • To differentiate causes based on sex and clinical presentation.

Summary:

  • A retrospective review of 45 patients (10 women, 35 men) without PSS admitted for digital necrosis was conducted.
  • In women, causes included atherosclerosis, paraneoplastic syndrome, thrombocythemia, and various connective tissue diseases. Men presented with arterial diseases (thromboangiitis obliterans, atherosclerosis), local syndromes (hammer's, thoracic outlet), cardiac embolism, antiphospholipid syndrome, and other connective tissue diseases.
  • A significant portion of causes remained diverse, with 4 patients (3 smokers) having an undetermined etiology, highlighting the complexity of digital necrosis.

Impact:

  • This study broadens the understanding of digital necrosis beyond PSS, particularly in men.
  • It emphasizes the need for comprehensive diagnostic workups, including vascular, cardiac, and autoimmune assessments.
  • Findings aid in refining differential diagnoses and guiding further research into less common causes of digital necrosis.
