title: Perianal melanoma disguised as hemorrhoids: case report and discussion.
abstract: Perianal melanoma is a very rare disease that carries a grave prognosis. The difficulty in making the diagnosis and the rarity of the disease results in failure of recognition until the disease is widespread. Ultimately, the burden is on the physician to uncover this ominous cancer. Not doing so is one of the most significant correlates to poor outcome.
