Abstract

Malignant nodular hidradenoma is very rare adnexal tumor with exceedingly low incidence of 0.001%. The biological behavior of the tumor is aggressive, with local recurrences reported in more than 50% of the surgically-treated cases. Treatment options are surgery and/or Radiotherapy. Till date there is no clear consensus on its treatment. We report a rare case of malignant nodular hidradenoma nose in an 80-years old male who responded miraculously to Radiotherapy.
