Anal Cancer in a Renal Transplant Recipient: a Case Report and Literature Review

Abstract

Anal carcinoma is a rare tumor in the general population accounting for 1%-2% of all malignancies. Most anal cancers are squamous cell carcinomas. Human papillomavirus and immunosuppression are the main risk factors for developing anal squamous cell carcinoma. Therefore, the incidence rate of anal squamous cell carcinoma is significantly higher in renal transplant recipients than in the general population. We present a patient who developed anal cancer nine years after renal transplantation. Since there was a significant diagnostic delay in our patient, we would like to emphasize the importance of regular screening for anal cancer in renal transplant recipients.
