Classification of the Hematologic Variations and Abnormalities Associated with Boeck ’ S Sarcoid

By MARCO BRUSCHI, M.D., AND JOHN S. HOWE, M.D. T HE PURPOSE of this paper is to classify the hematologic variations and abnormalities associ ated wi th Boeck’s sarcoid, to discuss whether the abnormalities are causally or coincidentally related and to present a case of thrombocytopenic purpura associated with sarcoidosis with recovery following splenectomy. It should be pointed out that although blood dyscrasias accompanying sarcoidosis are uncommon in the reported literature, they may be more common than is generally appreciated. Several examples’-2 can be found in which hematologic abnormalities reported in association with tuberculosis may be associated instead with sarcoidosis. In this report the hematologic findings associated with Boeck’s sarcoid will be reviewed under three general headings: (a) abnormalities of the erythrocytes, (b) abnormalities of the leukocytes and (c) abnormalities of the thrombocytes, including pancytopenia.
