Acral Lick Granuloma

Acral lick granulomas are skin lesions most commonly seen in young, large breed dogs. Lick granulomas result from an urge to lick the lower, front area of the legs. A lick granuloma is thickened, raised and red.

The condition has either psychologic or physiologic causes. Boredom is often the root cause of lick granulomas. The dog will lick at itself and cause breaks to occur in the dermis. These breaks become infected and itchy and the cycle is in place for granuloma formation. Additionally, allergic dermatitis may lead to very itchy skin and excessive licking.

Diagnosis of lick granuloma is a relatively simple process. It is very important to diagnose the underlying conditions, which encourage formation of lick granulomas. Diagnostic steps include skin scrapes, cultures and biopsies. Occasionally, blood tests are also helpful.

Treatment of lick granulomas involves topical applications to discourage licking, topical steroid and antibiotic therapy, steroid therapy to reduce itching and oral antibiotic therapy to prevent or treat secondary bacterial infections. Dogs with allergic dermatitis must also have their allergies treated. Elizabethan collars can also be used to prevent licking and allow healing to occur.

Many granulomas respond favorably to treatment while others do not. Because of the erratic response to therapy, it is necessary to monitor the lesion closely for signs of complications.
