Scurvy--The brave 2nd-year resident (John Crandon)

Petechiae, Purpura, Ecchymoses
Size seems to be the criteria. Petechiae (1-2 mm), Purpura (>3 mm), Ecchymoses (>1-2 cm).
The NEJM immune thrombocytopenia review from March (PubMed) has some pictures of more explicit petechiae. (Authors of same review do bone marrow on patients over forty years old.) Below 10,000 platelets risk of serious hemorrhage rises.
