Sigmoid carcinoma localized in the sac of a right inguinoscrotal hernia.

The inguinoscrotal hernia with colonic malignancy in the sac presents rare but severe consequence. The most common side of this type of hernia is the left one while the most common part of the large bowel is the sigmoid colon. The clinical picture can be easily confused with simple inguinoscrotal hernia unless the clinician is alert to the presence of certain sinister symptoms and signs. We report an extremely rare case of a 91-year-old man presented with anemia who had a right inguinoscrotal hernia containing a sigmoid colon carcinoma.
