Sigmoid carcinoma 2 – Example
This 67-year-old white male reported reduction in his physical performance over a period of about six months. He denied any digestive or abdominal complaints. Laboratory studies revealed iron deficiency anemia. Colonoscopy was performed after the patient had undergone gastroscopy with normal findings.
Colonoscopy revealed a tumor of the middle sigmoid colon extending over about 6 cm and taking in nearly half of the circumference. This did not prove a hindrance to the passage of the endoscope. No pathological changes were identified in any other segment of the colon.
Reduced physical performance and iron deficiency anemia occurring in older persons are always suspicious for a malignant process in the colon. Histological examination revealed an adenocarcinoma but there was no evidence of metastases to the lung, liver or lymph nodes. The patient was treated surgically. Surgical findings confirmed a stage III tumor.
