Nodular Dermatofibrosis
Nodular dermatofibrosis is a noncancerous skin disease associated with internal malignancy and recognized in 1967. It is most commonly seen in German Shepherd dogs but has been also reported in other breeds. This condition evolves as a series of lumps (nodules) which can number in the hundreds and are most often seen involving the areas between the toes and on the legs, but can also develop on the ears and back. They range from a few millimeters to 1.5 inches. They are round in shape, but when large, they can cause alopecia (hair loss) and ulceration of the skin. The overlaying skin may show some thickening and hyperpigmentation.
In areas of friction the nodules are often ulcerated. Although the lumps don't cause many problems themselves, they are typically associated with the development of cancers of the kidneys and/or uterus. In this case, the condition is referred to as Canine hereditary multifocal renal cystadenocarcinoma and nodular dermatofibrosis (RCND).
Any German Shepherd having lumps on their legs should be evaluated for the possibility of nodular dermatofibrosis. No dogs with this condition should be used for breeding and all should be screened for the present or future development of kidney or uterine tumors. Affected dogs should be evaluated at least once in three months, since with early recognition the kidney tumors may be surgically removed before the cancer has had time to spread. Pedigree analysis strongly indicates that the syndrome is hereditary, probably in an autosomal dominant pattern.
Early signs may include lameness caused by nodular growths on the limbs. In many cases, however, these growths may not bother the dog. It has been noted that female German Shepherds are more often affected than male dogs. The skin lesions may precede or occur simultaneously with the kidney tumors. Inflammation is usually minimal.
Unlike other skin growths, these lesions are not limited to the superficial layer of the skin (dermis) and their multiplicity is unique. The bulk of the lesions is in the deep dermis. When these lesions are found in female German Shepherds, they should be tested for kidney problems. Computed tomography (CT) examination is useful for the early detection of renal cystadenocarcinomas and for screening suspected carrier dogs before breeding. CT makes it easy to differentiate between cysts and solid tumors in the kidneys.
