AGGRESSIVE DIGITAL PAPILLARY ADENOCARCINOMA
By Gary M. White, MD
The aggressive digital papillary adenocarcinoma (ADPA) are rare cutaneous tumors of sweat gland origin. It can be aggressive, with metastasis or a high rate of recurrence.
A progressively-enlarging, multinodular papulonodule of the finger is characteristic. In one series [JAAD 2017;77;589] the majority of patients were men (89%), with a mean age of 47 years. A delay in diagnosis is typical, from years to decades, because the initial lesions seems benign, most closely resembling a cyst.
Wide local excision or amputation is appropriate.
