## Background: Immunoreactivity for chromogranin a (cg a) is associated with the presence of neurosecretory granules in tumor cells, but immunohistochemical staining for cg a may be absent in small cell lung carcinoma (sclc), which has only a few secretory granules. localization of cg a mrna is a u
W e read with great interest the article by Sumiyoshi et al., 1 in which the authors report that the detection of chromogranin A (Cg A) mRNA using a new in situ hybridization method is far more sensitive than immunohistochemistry. In their series, 100% of 20 small cell carcinoma (SCLC) cases were po
