Aggressive digital papillary adenocarcinoma 5 years after surgical resection of adenoma on index finger

Abstract

We experienced 72-year-old male who was diagnosed aggressive digital papillary adenocarcinoma (ADPAca) on his right index finger. He had a history of surgical excision of the tumor diagnosed aggressive digital papillary adenoma (ADPA) at the same site 5 years before. After the diagnosis of second surgery, we added the third surgery for wide resection. There are no recurrence and metastasis at postoperative 3 years after third surgery. ADPA and ADPAca have been considered to be different disease by the pathological findings. However, there were many opinions that they should be the same disease clinically because rates of metastasis and local recurrence had no difference in two diseases. Our case experience strongly supported the two diseases should be considered as the same disease. We recommend additional excision of the tumor even the pathological diagnosis is benign as ADPA.
