Granulomatous inflammation cat

A granulomatous inflammation occurs when the body, for example, cannot properly clear up an infection or a corpus alienum (foreign body). A well-known example of this is a tubercle (TBC) in an infection with mycobacteria. Then there grows a kind of chronic inflammation with accumulation of neutrophilic polymorphonuclear leucocytes, macrophages, epithelioid cells and giant cells (large erratic cells with multiple nuclei). You can also find lymphocytes and plasma cells in it.

Fibrosarcoma cat

A fibrosarcoma is a malignant tumor of mesenchymal connective tissue cells. Fibrosarcoma mainly occurs as a solitary tumor in the older cat. It can occur in several parts of the body. Usually on the trunk and often also between the shoulder blades, because injections are usually given here. First there is an injection site reaction that degenerates neoplastic. The rabies vaccine is known to be a possible cause of this. It is a malignant derailment of the dermal and subdermal connective tissue cells. The sarcoma grows locally very infiltratively and aggressively, not metastasizing quickly. But if so, then to the lungs and lymph nodes. Fibrosarcoma can also occur in young cats. In these cases it is often induced by a virus and there are multiple tumors over the entire body.
