Neuroendocrine cells associated with neuroendocrine carcinoma of the breast: nature and significance.

Aims: To investigate NE cells in the background tissues surrounding B-NECs.

Methods: Three cases (four breasts) having many NE cells in the background tissues of multifocal B-NECs were identified at the University of Yamanashi Hospital and St Luke's International Hospital, Japan.
