BIOPSY with microscopic (1 tissue) 
Test
SOURCE/HISTORY              
5 x 3 cm mass dorsal head.
 

MICROSCOPIC DESCRIPTION     
The large subcutaneous dorsal head mass contains a large area of
epidermal ulceration associated with fibrinosuppurative inflammation.
Majority of the mass consists of solid sheets and interwoven bundles
of mildly pleomorphic neoplastic fibroblasts associated with scattered
small islands of degenerate skeletal muscle. Skeletal muscle
interstitium contains loose connective tissue associated with moderate
ectasia of blood vessels. Mitotic count is approximately 20 per 10
high power fields. Neoplastic cells extend to sample edges.
 

DIAGNOSIS                   
Fibrosarcoma
 

COMMENTS                    
Fibrosarcoma in cats is a clinically aggressive tumor. There is a very
high rate of recurrence and narrow excision is invariably followed by
eventual recurrence. Wide excision with 2-3 cm margins is often
required to achieve a satisfactory remission time. Metastatic
potential is relatively low. Adjunctive therapy may improve the
clinical outcome and consultation with an oncologist may be helpful.
