Case Report of Acquired Digital Arteriovenous Malformation Regression After Biopsy

A 104.7 KB DOCX file contains a detailed case report of a rare vascular anomaly. The report describes a 65-year-old male patient with a toe-localized acquired digital arteriovenous malformation (ADAVM) that regressed after a diagnostic skin biopsy. Authored by figshare admin karger and last updated in June 2026, the document includes clinical presentation, dermoscopy, and histopathological findings.

Use Cases

• Studying the clinical presentation and regression of rare vascular anomalies based on the detailed case description
• Analyzing histopathological features of acquired digital arteriovenous malformations based on the reported examination findings
• Reviewing dermoscopic patterns for vascular lesions based on the described hairpin vessels with a white halo
• Investigating the potential role of biopsy-induced hemodynamic changes in lesion regression based on the case conclusion

Strengths

• The case report provides a detailed clinical and histopathological description of a rare condition (toe-localized ADAVM).
• The document is licensed under CC-BY-4.0, allowing for open sharing and reuse.

Limitations

• The dataset is a single case report (104.7 KB), representing an extremely limited sample size of n=1.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect the specific bias inherent to a single case report from an unspecified source.
