Giemsa is what we use routinely for mast cell neoplasms and normal mast cells. For us it works equally well as T blue for diagnostic purposes. Our positive control is a cutaneous mast cell tumor (very common in out animal species), or skin biopsy with allergic dermatitis. 

Poorly granulated/degranulated mast cells won't stain with Giemsa or T Blue, and in those cases we use c-Kit IHC

Subject: [Histonet] mast cells for arteries

Does anyone have a go to stain for Mast Cells besides Tol Blue?  We are
trying to demonstrate the presence of mast cells in human arteries ffpe.
Also, what would be a good positive control to use for mast cell staining,
we used NH Skin and got maybe a few mast cells but I would like to use
something more abundant with mast cells.
