Diagnosis

Expand Diagnosis

NODULAR HISTIOCYTIC HYPERPLASIA IN THE FALLOPIAN TUBE Originally called nodular histiocytic and mesothelial hyperplasia, it was reported in hernia sacs and was believed to be of predominant mesothelial cells. The advent of immunohistochemistry indicated that the vast majority of the cells are histiocytes. In the gynecologic tract it is reported in the endometrium also, where it can simulate neoplasia.
