title: [Sarcoid nodules of the skin at the site of venipuncture (author's transl)].
abstract: In a 56-year-old female patient with sarcoidosis, venipuncture for withdrawal of blood specimens resulted in the formation of a histologically confirmed sarcoid granuloma at the precise site of the puncture. Eight similar cases are reported in the literature. They concern women aged 37 on average and presenting with pulmonary lesions. The sarcoid nodules, large or small, occurred earlier at the sites of venipuncture than on visible scars. One may wonder whether the formation of these nodules could be due to a hypersensitivity reaction developing as a result of blood cells extravasation during an active phase of the disease.
