Acrocyanosis: primary or secondary form? An observational study.

Area of Science:

• Vascular Medicine
• Rheumatology
• Dermatology

Background:

• Acrocyanosis is a common vascular disorder with functional microcirculatory changes.
• It's classified as primary or secondary, with secondary forms linked to other conditions.

Purpose of the Study:

• To investigate the association between acrocyanosis and connective tissue diseases (CTDs).
• To identify risk factors for secondary acrocyanosis.

Main Methods:

• Study included 53 patients diagnosed with acrocyanosis (mean age 35).
• 45.3% of patients had secondary acrocyanosis.
• Statistical analysis identified risk factors.

Main Results:

• Advanced age (≥ 40 years) significantly increased the risk of secondary acrocyanosis.
• Connective tissue diseases were the most frequent associated conditions (32% of all patients, 71% of secondary cases).
• No significant sex-based differences were found.

Conclusions:

• Acrocyanosis, while often benign, can indicate underlying systemic diseases.
• A high prevalence of secondary acrocyanosis associated with CTDs was observed.
• Clinical evaluation, capillaroscopy, and antinuclear antibody testing are recommended for suspected cases.
