Pancreatitis

• Hypersensitivity
• Allergies to fleas, food or inhalants

• Linear in shape
• Pink-yellow in color

• Corticosteroids
• Antibiotics

• Come from mesenchymal cells and are named by the specific cell type such as fibroblasts (fibrosarcoma) and osteoblasts (osteosarcoma). 
• Cytologically, they tend to appear as isolated spindle-shaped cells with elongated cytoplasm and often oval nuclei. 

• Come from epithelial cells including cells of glandular tissues such as salivary glands, mammary glands, and cells lining most tissues including squamous cells or transitional cells. 
• The cytologic appearance is that of cohesive clusters of cells. Cells are often polygonal in shape. 

• There are 5 round cell tumors and most but not all come from blood cells. They are lymphoma, mast cell tumors, plasma cell tumors, histiocytic tumors, and transmissible venereal tumors. 
• These are sometimes also referred to as sarcomas (i.e. lymphosarcoma or histiocytic sarcoma). 
• Cytologically, they appear usually as large populations of cells that are not in defined clusters. The cells have a round shape, often with unique identifiable features such as the purple granules in mast cell tumors.
