Aggressive digital papillary adenocarcinoma diagnosed by fine needle aspiration cytology.

Aggressive digital papillary adenocarcinoma is a rare variant of eccrine sweat gland malignancy with a propensity for metastases and recurrence. We report a 45-year-old female with aggressive digital papillary adenocarcinoma diagnosed by fine needle aspiration cytology (FNAC). The cytological findings were representative of the histological features. The recognition of aggressive digital papillary adenocarcinoma as a distinct clinicopathological eccrine sweat gland neoplasm is important because of the potential for aggressive local growth and distant metastasis. FNAC plays an important role in the preoperative diagnosis and management of these lesions.
