Table 5 Tryptase, ER-a, and E2 positive mast cells in IH, VM, and normal skin samples

From: Estrogen is involved in hemangioma regression associated with mast cells

Specimens Typtase positive, mean ± SD cells/HPF ERa positive, mean ± SD cells/HPF E2 positive, mean ± SD cells/HPF
IH (n = 29) 30.6 ± 12.7 9.7 ± 5.6 19.8 ± 8.7
VMs (n = 33) 9.0 ± 9.8 1.5 ± 2.4 2.5 ± 4.1
Normal Skin (n = 15) 6.1 ± 8.5 0.5 ± 1.2 1.9 ± 3.4
  1. IH contained significantly more Typtase, ERa and E2 positive mast cells (p < 0.05)
