Abstract
Digital papillary carcinoma (DPC) is a rare, slow growing, malignant tumor with eccrine differentiation that occurs predominantly in digits. This tumor was originally classified as a benign neoplasm; aggressive digital papillary adenoma (ADPA) was first described by Helwig in 1979.1 In 1987, Kao et al.2 classified ADPA and aggressive digital papillary adenocarcinoma (ADPAca) based on differences in histologic findings. However, a recent retrospective study revealed that neither histologic nor clinical characteristics were predictive of recurrence or metastasis. 3 Therefore, the designations “ADPA” or “ADPAca” should be reevaluated because lesions with benign histologic features have both recurred and metastasized.3 In the 2006 World Health Organization (WHO) classification, ADPA or ADPAca were grouped under a single entity of DPC without any benign counterpart. 4 We report a case of DPC on the third finger that lastedfor 20 years, but increased in size and became extremely painfulin the past 7 months. After a complete excision, no recurrence
or metastasis was found for two and a half years. A brief review of the literature is presented.
