Diagnostic Pathology, 06/29/2012
Li H et al. – The authors report the case of a 60–year–old male patient with primary malignant melanoma of the duodenum, which was misdiagnosed as lymphoma or undifferentiated carcinoma in frozen consultation. The patient had achieved disease–free survival for more than 46 months without any evidence of recurrence after surgery.
