Hemangiosarcoma of the skin in a dog. Hemangiosarcoma is quite common in dogs, and more so in certain breeds including German Shepherds and Golden Retrievers. [3] It also occurs in cats, but much more rarely. Dogs with hemangiosarcoma rarely show clinical signs until the tumor has become very large and has metastasized.
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma , known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life.
The corduroy sign reflects the characteristic trabecular changes caused by the hemangioma, namely, thinning of trabeculae as well as thickened vertical struts, resulting from compensatory hypertrophy of the remaining trabeculae to maintain structural integrity. These vertical trabecular striations give rise to the "corduroy" appearance on imaging.
Histiocytic diseases in dogs are a group of diseases in dogs which may involve the skin, and which can be difficult to differentiate from granulomatous, reactive inflammatory or lymphoproliferative diseases. The clinical presentation and behaviour as well as response to therapy vary greatly among the syndromes.
