Case study 1/4: Mr. Harris brought his 8-year-old, MN boxer, Prince, into your clinic because they found a small raised lump on his thigh. Mr. Harris first noticed the lump four days ago and states the lump has increased in size since since they first felt it. Upon examination, Prince is found to be normal other than having a 1 cm raised, non-ulcerated solid mass on his upper thigh. Your veterinarian asks Mr. Harris for consent to take a fine needle aspirate of the mass to obtain a cytology sample. What are some benefits to using a fine needle aspirate? What is a disadvantage?
