Mastocytomas of skin are fairly common in both canine and feline so a
friend working in companion animal vet path would help. Some mastocytomas
are loaded with granules while poorly dofferentiated tumors may show only
focal granularity in some cells. In common human material, nerofibromas,
myxoid fibroadenomas and allergic sinonasal polyps are good bets to contain
scattered mast cells. Look for ovoid to dendritic cells with blue granules
and small oval central nucleus.
