Difference between revisions of "Dermal cysts"

The section shows hair-bearing skin with a deep sinus tract containing large clusters of neutrophils, abundant plasma cells, hemosiderin-laden macrophages, eosinophils and multinucleated giant cells.  It is well vascularized and surrounded by a fibrotic tissue.  Benign, fibrofatty tissue with scant inflammation completely surrounds the tract, in the plane of section; however, it is focally fragmented. There is no squamous lining within the sinus.  No nuclear atypia is identified.
