SKIN (PILONIDAL SINUS), EXCISION:

- 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.
