Aggressive digital papillary adenoma (ADPA) is a rare tumor of the sweat glands. They usually present as solitary masses, with or without pain, and are most commonly observed in the fingers. A 19-year-old man presented with a solitary, protruding lesion on the right big toe that had enlarged 6 months previously. The biopsy specimen revealed a well-marginated mass with papillary projections and tubular structures. On foot magnetic resonance imaging, there was no invasion, and chest radiography showed no metastasis. Based on these findings, the tumor was diagnosed as ADPA, and wide excision was performed. Herein, we report a rare sweat gland tumor on the toe that was diagnosed as an ADPA.
