K. Nakajima et al., Chromogranin a expression in hepatocellular carcinoma in a patient with germline MEN1 gene mutation, INTERN MED, 39(1), 2000, pp. 20-24
Hepatocellular carcinoma (HCC) was found in a patient with multiple endocri
ne neoplasia type 1 (MEN 1), The intriguing finding was that the WCC in the
patient was positively stained for chromogranin A (CgA), a cellular marker
for endocrine and neuroendocrine tumors. The patient had a pancreas endocr
ine tumor and type C hepatitis, that made pathological diagnosis of the ori
gin of the tumor complicated.
