A case report of primary malignant melanoma of the esophagus followed using serum 5-s-cd levels

Abstract

An 80-year-old man presented to hospital for treatment of primary malignant melanoma of the esophagus. The lesion was initially considered to be melanosis of the esophagus and was found on July, 2005. 20 months later, the lesion was found to be slightly elevated and more densely pigmentated. Given the patient's general condition, a blunt dissection of the esophagus was done. The patient's serum 5-S-cysteinyldopa(5-S-CD) level was high on admission and decreased after surgery ; no increase was seen until Prior to the patient death following a cerebral infarction in December, 2006. Changes in serum 5-S-CD levels in case with primary malignant melanoma of the esophagus are likely useful in following the so patients.
