Abstract

Glomic tissue occurs at the bifurcation of the pulmonary trunk. There is controversy as to its derivation, blood supply, and function. It has been regarded as one of the coronary glomera supplied by the intertruncal branch of the left coronary artery. On the other hand, it has been described as the true glomus pulmonale supplied by blood from the pulmonary trunk. The purpose of this article is to draw attention to its existence and to establish its microanatomical structure.
