Decreased expression of neuropeptides in malignant paragangliomas: an immunohistochemical study.

abstract：:The histologic findings in lymph nodes were used to identify eight patients, who are not in a high-risk group, with human immunodeficiency virus (HIV) infection. In order to determine the specificity of these findings, the histologic and clinical findings in these patients were compared with the histologic and clinica...
