			TENOSYNOVIUM, LEFT MIDDLE FINGER, EXCISION:
			- DENSE CONNECTIVE TISSUE (CONSISTENT WITH TENDON) WITH LYMPHOHISTIOCYTIC INFILTRATE.
			- NEGATIVE FOR GIANT CELLS.
			- NEGATIVE FOR MALIGNANCY.
			</pre>

			====Micro====
			The sections show dense connective tissue (tendon) containing a cluster of cells with
			indistinct cellular borders, abundant foamy grey cytoplasm, and round/oval
			pale-staining nuclei with small nucleoli (histiocytes). The cell cluster has a small
			number of interspersed lymphocytes, and the centre of the cell cluster has acellular
			hyaline material (degenerative tendon).

			No calcification is identified. No giant cells are seen.

			No nuclear atypia is apparent and no mitotic activity is appreciated.

			=====Alternate=====
			The sections show dense connective tissue (tendon) containing rare histiocytes and
			lymphocytes. No calcification is identified. No giant cells are seen. No nuclear atypia
			is apparent and no mitotic activity is appreciated.
