Carcinoma Rectum with Prostate and Urinary Bladder Metastasis- A Rare Case Report

Abstract

Tumours of the colon and rectum are one of the most common malignancies worldwide. In India, its incidence is less compared to the developed countries however,recently it has increased from past few decades due to sedentary lifestyle and more consumption of animal fats with less dietary fibre intake. The liver and lungs are most common sites of metastasis from colorectal carcinoma; however, it occasionally metastasised to atypical sites by making diagnosis difficult. Due to the high frequency of colorectal carcinoma, even infrequent metastatic sites are important to diagnose as early as possible. Hereby, authors present a case of 53- year-old male, with history of carcinoma rectum and treated with Abdominoperineal Resection (APR) with permanent colostomy three years back. Three years after the diagnosis of carcinoma rectum, the patient was diagnosed with metastasis of colorectal adenocarcinoma to prostate and urinary bladder which was proven histopathologically. Despite the fact that this condition is uncommon in clinical practice, the possibility of metastatic involvement of prostate and urinary bladder should always be considered when the diagnosis of other primary carcinoma is made.
