Metastatic Malignant Melanoma of the Small Intestines Diagnosed by Capsule Endoscopy

Malignant melanoma is a fairly common tumor that shows an unusual predilection to metastasize to the small intestines. The time interval between the diagnosis of metastasizing melanoma and the initial diagnosis is variable. This as well as the non specific symptoms and the fact that the small bowel is inaccessible both radiologically and endoscopically lead to delay in diagnosis. We present a case of metastatic malignant melanoma to the small intestines diagnosed several years post excision by capsule endoscopy. Metastatic melanoma in the small bowel should be suspected in any patient with a previous history of malignant melanoma who develops non specific gastrointestinal symptoms. Capsule endoscopy which is non invasive, convenient to the patient and devoid of radiation should form part of their diagnostic investigation.
