Soft tissue sarcoma refers to a broad group of tumors that originate from connective tissues. They tend to have similar histologic appearance and biological behavior, and can be either benign or malignant. Soft tissue sarcomas can arise in any part of the pet's body but skin and subcutaneous tumors are the most commonly observed.
Soft-tissue sarcomas commonly originate in the upper body, in the shoulder or upper chest. Some symptoms are uneven posture, pain in the trapezius muscle, and cervical inflexibility [difficulty in turning the head]. [12] The most common site to which soft-tissue sarcoma spreads is the lungs. [13]
FMTs are a heterogeneous group of soft tissue neoplasms (i.e. abnormal and excessive tissue growths). The World Health Organization (2020) defined tumors as being FMTs based on their morphology and, more importantly, newly discovered abnormalities in the expression levels of key gene products made by these tumors' neoplastic cells.

A hemangiopericytoma is a type of soft-tissue sarcoma that originates in the pericytes in the walls of capillaries. When inside the nervous system, although not strictly a meningioma tumor, it is a meningeal tumor with a special aggressive behavior. It was first characterized in 1942. [2]
Immune therapy based on cultivation of tumor tissue is being developed for dogs. [22] A preventive vaccine based on several proteins commonly found in dog cancers, including hemangiosarcomas, is also being developed. [23] In the skin, it can be cured in most cases with complete surgical removal as long as there is not visceral involvement. [4]

malignant fibrous histiocytoma: This tumor is now termed undifferentiated pleomorphic sarcoma (UPS) because more recently developed immunohistochemistry and cytogenetic analyses suggest that its neoplastic cells most likely arise from mesenchymal stem cells [5] or fibroblasts [6] rather than histiocytes. histiocytoma (dog)
Illustration of venereal granulomata on a dog's penis. A canine transmissible venereal tumor (CTVT), also known as a transmissible venereal tumor (TVT), canine transmissible venereal sarcoma (CTVS), sticker tumor and infectious sarcoma, is a histiocytic tumor of the external genitalia of the dog and other canines, and is transmitted from animal to animal during mating.
