Glomus coccygeum: a review

Pathologica. 2018 Dec;110(4):287-293.

Abstract

With limited information about the coccygeal glomus found in classic textbooks, we deemed it necessary to review the subject. The illustrations presented in this article derive from four coccygeal glomera incidentally encountered during examination of pilonidal disease specimens. Familiarization with its microanatomical features may help to avoid inappropriate interpretation of this enigmatic structure.

Keywords: Arterio-venous anastomosis; Coccygodinia; Glomus coccygeum; Glomus tumor; Sucquet-Hoyer canals.
