Abstract
We report here on a case of fibrovascular polyp arising in the hypopharynx of a 62-year-old man. Laryngomicroscopic surgery with laser ablation was performed to excise the mass. Histopathologically, the surface of the polyp was covered with mature squamous epithelium. The polyp showed a characteristic lobular proliferation of mature adipose tissue that was separated by myxoid or collagenous connective tissue. Some scattered skeletal muscle bundles were seen in the central portions of the polyp and these bundles were surrounded by a concentric proliferation of the spindle cells; this was reminiscent of Pacinian corpuscles. Regarding their location and the intermingled pattern of proliferating tissues, it is more plausible that the skeletal muscle is a hamartomatous component rather than entrapped, preexisting tissue.
