Percentage of mast cell cellularity observed on bone marrow biopsy specimens correlated with serum tryptase levels for ISM. Data shown are for bone marrow biopsy specimens in which there was a tryptase level obtained at the time of biopsy (n = 32). Green circles indicate UP (n = 6), filled squares indicate DCM (n = 7), open squares indicate mastocytomas (n = 2), and triangles indicate ISM (n = 17). The 2 children with a nodular subtype did not have a bone marrow biopsy performed. Note that some data points superimpose. Correlation coefficient Spearman rho = 0.84 (P < .0001) for SM and Spearman rho = 0.41 (P = .363) for DCM. UP values are all 1% or less, with no correlation.
