Aggressive Digital Papillary Adenocarcinoma

It is more common in men, has a mean age at presentation of 52, averages 1.7 cm in greatest dimension and may be present for up to 15 years. The term "aggressive digital papillary adenoma" has been abandoned, given that despite their bland appearance, they often behave aggressively.

Management Aggressive surgical re-resection or amputation if necessary to avoid local recurrence.
