Immunohistochemical study of Non-Hodgkin Lymphoma presenting in head and neck region

ABSTRACT

Thirty-four patients with NHL presenting in the head and neck region were studied clinically, histologically and by immunohistochemistry using the B-cell markers, T-cell markers, histocytic markers and transferrin markers. The peroxidase antiperoxidase technique was adopted. According to the immunologic phenotypes, 19 cases were B- cell, 7 cases were T-cell, while 7 cases were null. The immunohistochemistry was very helpful in diagnosing high grade lymphomas, especially the undifferentiated and histocytic types
