Chronic, episodic thrombocytopenia. A case report with long-term observation

Clin Pediatr (Phila). 1990 Mar;29(3):179-81. doi: 10.1177/000992289002900308.


A male patient with chronic idiopathic thrombocytopenic purpura (ITP) did not fit into any of the known risk groups for chronic ITP. He was unique in that he manifested a cyclic increase of platelet counts each winter followed by a nadir in the summer, without having other hematologic abnormalities.
