Aggressive digital papillary adenocarcinoma - a rare malignant tumor of the sweat glands: two case reports and a review of the literature.

Abstract

Aggressive digital papillary adenocarcinomas are rare malignant tumors often located on the digits of the hand. Due to lack of pain, slow growth, and an inconspicuous appearance, diagnosis is often missed or delayed. We report two cases and review the present literature to give recommendations for diagnosis and treatment.
