Survival outcomes of anal adenocarcinoma versus rectal adenocarcinoma: A retrospective cohort study

Uncommon Anal Cancers

Anal cancer is by itself a rare entity. Even rarer are the uncommon anal tumors described in this article. Diagnosis of these lesions can be challenging as some of these have no symptoms in their initial stages and only cause symptoms once they have progressed to advanced stages. Further, it can be difficult for even the trained eye to make a diagnosis as some of these pathologies mimic benign disease or the more common anal malignancy, squamous cell carcinoma. More data are needed to establish consensus for the management of these unusual pathologies.
