[Extreme thrombocytopenia in sarcoidosis (author's transl)].

A report on a 17-year-old patient with sarcoidosis who was admitted to hospital because of acute generalized tendency to hemorrhage in very severe thrombopenia. This type of thrombopenia has a high primary mortality rate unless steroids are administered in high doses in good time. If the patient survives this crisis, the prognosis for him and the sarcoidosis is good.
