在视野中心是一个嗜碱性细胞，它有一个多叶核（象PMN的核），并且细胞质里有为数众多的粗糙的、深蓝色的颗粒。它们在正常的外周血涂片中是很少见的，而且它们的意义还不确定。左上是一杆状核嗜中性粒细胞，右下可见一个大的、已活化的淋巴细胞。）
There is a basophil in the center of the field which has a lobed nucleus (like PMN's) and numerous coarse, dark blue granules in the cytoplasm. They are infrequent in a normal peripheral blood smear, and their significance is uncertain. A band neutrophil is seen on the left, and a large, activated lymphocyte on the right.
