Skin mass from a dog
A 5-year-old male castrated Labrador Retriever was presented for a mass on the right forelimb. The owner first noted the mass about a week ago and noted that it had gotten slightly bigger since that time. The dog had also been seen licking at the lesion. The dermal mass was ~1cm in diameter, round, raised, somewhat firm, and appeared superficially irritated. It was located on the dorsal surface of the 5th digit. The submitting veterinarian performed a fine needle aspirate and submitted Diff Quik®-stained squash prep smears for cytologic evaluation.
