On March 8, 2011
Zoom, a 4 year old Sicilian Donkey, was brought in
with a large pendulous growth hanging from his upper left
eyelid.
|
 |
|
|
Zoom was presented with a large
periorbital (pertaining to the area surrounding the
socket of the eye) tumor along the dorsal left
eyelid. The tumor was a large, pedunculated
(referring to a lesion attached with a narrow,
stalk-like base) mass that obscured the left eye,
but had not invaded the eye tissue.

|
Surgical Removal
The tumor was surgically removed and the tissue of
the upper eyelid was resected with as wide a margin
as was possible. It is thought that cryotherapy
might be necessary if small tumor masses returned
along the margins.

Cryotherapy
Definition
Cryotherapy is a technique that uses an extremely
cold liquid or instrument to freeze and destroy
abnormal skin cells that require removal. The
technique has been in use since the turn of the
century, but modern techniques have made it widely
available to dermatologists and primary care
doctors. The technique is also called cryosurgery.
Purpose
Cryotherapy can be employed to destroy a variety of
benign skin growths, such as warts, pre-cancerous
lesions (such as actinic keratoses), and malignant
lesions (such as basal cell and squamous cell
cancers). The goal of cryotherapy is to freeze and
destroy targeted skin growths while preserving the
surrounding skin from injury.

Today
At the time of his post-operative recheck, the
sutures were removed and it was found that the
surgery site had healed extremely well. No tumor
re-growth was noted at that time.
It
is
possible that sometime in the future Zoom may have
other tumors return to that area,
but for the moment, it is nearly impossible to tell
he ever had the first one.
