Feline acne is a problem seen in cats primarily involving the formation of blackheads accompanied by inflammation on the cat’s chin and surrounding areas. In many cases symptoms are mild and the disease does not require treatment. More severe cases, however, may respond slowly to treatment and seriously detract from the health and appearance of the cat. Feline acne can affect cats of any age, sex or breed.
Sebaceous glands are mostly found in the skin of the chin, base of the tail, eyelids, lips, prepuce and scrotum. They are connected to the hair follicles. In acne, the follicles become clogged with black sebaceous material, forming comedones (also known as blackheads). These comedones can become irritated, swollen and infected, leading to pustules. The cats may experience itching and discomfort due to swelling and bacterial growth inside infected glands. Secondary fungal infections (species Malassezia) may also occur.

There is a lump or bump, so you visit the vet to see what it is. Fortunately most of these are benign growths. Here are the specifics that you need to know.
SIGNS Most lumps are easy to feel. They may show up on the chest or along the back. Most lumps on dogs are benign. Often while petting your pet a cyst becomes noticeable.
CAUSES As your pet ages, its immune system becomes less effective and lumps and bumps become more prevalent. Common dog lumps are lipomas (benign fatty tumors) and sebaceous cysts (a skin gland that blocks up).
