This is an uncommon inflammatory condition of subcutaneous fat in which lumps appear over the back and along the sides of the body, much like marbles beneath the skin. These lumps are more apparent in shorthaired breeds. As the disease progresses, the lumps ulcerate and drain, then heal by scarring. The dog usually runs a fever and appears lethargic. The cause of the disease is unknown. Biopsy of a nodule confirms the diagnosis.
Treatment: Surgical excision is the treatment of choice for a solitary nodule. With multiple nodules, treatment involves corticosteroids and/or vitamin E. The outlook for long-term recovery is good.
