The consensus between routine cytology and histopathology for staging lymph nodes in patients with melanocytic neoplasms is poor [49]; however, in one study, there appeared to be increased detection of amelanocytic forms with ICC for Melan-A on fine-needle aspirate samples, particularly when cells were low in number or of round cell morphology [15,50]. The gene discussed is MLANA; the disease is intrahepatic cholangiocarcinoma.
