SYSTEMIC MASTOCYTOSIS: BONE MARROW INVOLVEMENT Figure 3-117 SYSTEMIC MASTOCYTOSIS: BONE MARROW INVOLVEMENT Paratrabecular aggregates of spindle-shaped mast cells are seen (A,B). These show metachromatic staining with Giemsa (C) and express CD117 (D). More about this image found in SYSTEMIC MASTOCYTOSIS: BONE MARROW INVOLVEMENT Paratrabecular aggregates o...

CUTANEOUS MASTOCYTOSIS Figure 3-112 CUTANEOUS MASTOCYTOSIS A: The mast cells are few in number and display a perivascular orientation. B,C: There is a prominent infiltrate of mast cells, seen at low- (B) and high- (C) power magnification. The mast cells form aggregates and infiltrate between More about this image found in CUTANEOUS MASTOCYTOSIS A: The mast cells are few in number and display a p...
