#The histiocytic type occurs in young cats (<4 years of age) and is most common in Siamese cats. It frequently presents as subcutaneous nodules. Histologically, the mast cells are poorly granulated and lymphoid aggregates are common. Many of these tumors will spontaneously regress.

#The ‘mast cell form’ of cutaneous MCT tends to occur in mixed breed shorthaired cats. Lesions tend to be solitary and are discrete, nodular, papular, or plaque-like lesions in the dermis or subcutaneous tissue. It can also present as ‘miliary dermatitis’.
