Digital papillary adenocarcinoma (DPA) is a rare and aggressive tumor arising from
the eccrine sweat glands. It is found on the hands and feet and most commonly occurs
on the volar and distal finger tips. In this report, we describe a DPA in a 45-year-old
woman who presented with a slowly enlarging mass on the dorsal aspect of her proximal
ring finger. This report shows that DPA may clinically present as a relatively benign-appearing
mass and in an atypical location. Surgical excision, followed by histologic and immunohistochemical
evaluations of even benign-appearing digital masses, is important because this is
the only way a DPA can be diagnosed.
