title: Hidradenocarcinoma of the finger.
abstract: Hidradenocarcinoma is a rare adnexal neoplasm representing the malignant counterpart of hidradenoma derived from eccrine sweat glands. Misdiagnosis of this disease is common due to the wide variety of histological patterns and rarity of this malignancy. We report an 87-year-old man presenting with a rare case of biopsy-proven hidradenocarcinoma of the finger. There is no standard care of treatment of hidradenocarcinoma, especially of those tumors in rare locations such as the fingers, given its rarity, variable tumor behavior and histology. Although limited treatment strategies exist, detailed data including TNM, location, histologic type and grade, and patient age should be gathered for optimal treatment strategy. The literature supports a 3-fold approach to these malignancies involving margin-free resection, sentinel lymph node biopsy to evaluate possible metastasis, and long-term follow-up given high risk of recurrence. Our treatment strategy involved a 4-fold, multidisciplinary approach involving reconstruction to optimize tumor-free remission and hand function.
