Abstract
Adenocarcinoma is extremely uncommon in the digits with an incidence of 0.08 per 1 000 000 people per year, known as digital papillary adenocarcinoma (DPA). This disease is commonly described pathologically as malignancy of the sweat glands. The fundamental histologic characteristics of DPA are the presence of papillary projections in cystic spaces in a multinodular tumor lined by epithelial cells. DPA are often delayed in diagnosis because of either misdiagnosis for benign lesions or underreporting, which can contribute to poor prognosis and metastasis. This report serves to present a case of recurrence observed in primary digital adenocarcinoma and to bring awareness to the topic as concrete management continues to develop.
