- PILONIDAL SINUS. | |||
- NEGATIVE FOR MALIGNANCY. | |||
</pre> | |||
====Micro==== | |||
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. | |||
