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