3377. A 7-month-old hamster has an itchy right knee lump. What to do?

Image post op sent to owner as educational material and evidence of surgery.

lump has pus deep inside. I electro excised the lump, used forceps to
 drain out the dry pus. No suturing was needed. Went home 4 hours later.

Post-op images show no skin lump. Sent by WhatsApp to owner as evidence of elecgtro-excision. Hence a good camera is important. No stitching necessary. Close up image shows rough skin above the lump due to long-standing itchiness and licking by hamster for many days before lump removal.
