Cat skin problems can be difficult to diagnose.
Veterinarians will first try and classify the skin problem based on its
appearance. Cat skin lumps and bumps or lesions (problem area on the
skin) tend to fall into certain broad categories.
Types of Cat Skin Problems
Macule: A macule is a
area of the skin where there is a change in color. Common causes are
some type of inflammation or injury.

Papule: A papule is
a type of lesion that is elevated. If it is large it is called plaque.
This type of cell inflammation is commonly called a neoplasm (which
refers to any type of cells, not just papules). A bigger papule is
called plaque. A neoplasm can be benign (not cancer) or malignant
(cancerous that spreads).

Postule: A postule is
an area on the skin that is filled with pus. Pus is caused by white
blood cells that are sent to kill a foreign invader such as bacteria or
a fungus. The dead cells create a lump on the skin called a postule.

Vesicle: This is a
lump underneath the skin that is filled with an unusual amount of fluid
(called edema).

Wheal: A wheal is a
raised area that tends to heal by itself in minutes or hours. It is an
area with increased redness or has a pale color when compared to
surrounding areas. It is also referred to as a cat hive with symptoms
such as severe itching. Common causes include certain foods or drugs,
infection, insect bites or allergy.

Nodule: A nodule is
a larger elevated bump on the skin. Causes include an abnormal cell
growth (neoplasm that is benign or malignant). It can also be caused by
bacterial or fungal infection.

large tissue mass. It is caused by abnormal cell growth (neoplasm that
is benign or malignant) or due to some type of inflammation.

Symptoms of Feline Skin
Disorders
Symptoms of feline skin problems include:
* Dry, flaky skin
* Red, irritated looking skin called skin lesions
* Loss of hair (called cat alopecia)
* A dry, dull-looking coat
* Lumps or bumps on or under the skin
* Red patches on the skin
* Round raw lesions on the head, hips and chest called cat
hot spots
* Scaly patches or scabs on the skin
* Your cat may scratch or lick her skin excessively (called pruritis)
Diagnosis of Cat Skin
Problems
Your vet will examine your cat’s skin carefully as part of a complete
examination. In order to properly diagnose skin ailments, various tests
may be needed. Tests might include:
* Examining skin under a special light (a woods
lights)- this is done to check for certain fungal infections such as
ringworm.
* A biopsy - in this test, a needle is used to
remove cells from a lump to be examined by a pathologist. This can
determine if a lump is cancerous or if it is just a cyst or wart.
* Blood tests - might be done to check for
infections and certain nutrient deficiencies.
The location
of the cat skin disorder can also indicate the type or
problem your cat might have. For example feline skin problems on the
ear can indicate mites or food allergy, a facial problem could be mange
and near the tail is most likely a problem with fleas.
Certain breeds are
associated with cat skin problems. There are also problems that are
unique to kitten skin.
Treatment of Cat Skin
Problems
The treatment of the diseases and conditions associated with feline
skin problems depends on the exact disease or condition.
Treatment may involve oral or topical medications.
Medicated shampoos may be prescribed. If your cat has scratched herself
too much, antibiotics may be necessary, as a secondary bacterial
infection may have set in.
Treatment may also involve surgical removal of any
lumps or bumps from your cat’s skin. This is usually only done if the
growth is cancerous or if it seems to be bothering your pet. If it is
benign and is not causing your cat discomfort, it can be left alone.
There are several over the counter homeopathic
products that could help to improve overall skin and coat condition
such as Skin
and Coat Tonic. Other over the counter products such
as Dermasol
contain Vitamin A, which can help to promote the healing of skin.
