A case report of a 12-year-old spayed female Golden Retriever with a 4-mont
h history of persistent diffuse erythema involving the right and left anteb
rachia is presented. Cutaneous biopsies revealed superficial dermal vascula
r dilation and proliferation with moderate epidermal acanthosis. Diagnostic
tests failed to reveal an underlying aetiology. Telangiectasia is defined
as a permanent dilation of pre-existing blood vessels creating small focal
lesions. Generalized essential telangiectasia of humans is common in women
of middle-age and can involve entire segments of the body. Lesions predomin
antly affect the extremities and can persist for years without any systemic
effects. The cutaneous lesions in this case have remained static for 3 yea
rs with no manifestation of systemic signs. A diagnosis of idiopathic telan
giectasia was made based on the clinical and histological findings in the d
og of this report. The lesions described in this dog resemble generalized e
ssential telangiectasia of humans.
