Spindle cell sarcoma is a type of connective tissue cancer. The tumors generally begin in layers of connective tissue, as found under the skin, between muscles, and surrounding organs, and will generally start as a small, inflamed lump, which grows in size. At first, the lump is, small in size, as the tumor exists in stage 1, and will not ...
The symptoms depend on the tumor's location and degree of invasion. For example, tumors in the gastrointestinal tract may cause vomiting, diarrhea, or weight loss. Tumors in the mouth may cause bad breath, difficulty swallowing, or lack of appetite. Tumors arising in the peripheral nerves may cause pain, lameness, or neurological symptoms.
Dogs can develop many of the same types of cancer as humans. Many canine cancers are described with the same terminology and use the same classification systems as human cancers. [1] Mast cell tumors are the most common type of skin cancer in canines. [1] Lymphoma; Prostate cancer; Brain cancer; Hemangiosarcoma is a type of cancer that is ...
Urinary System Cancer. Transitional cell carcinoma, a type of cancer most commonly seen in a dog's bladder, may respond to ivermectin in the same way as human renal cell carcinoma.

The tumor may present different degrees of differentiation: low grade (differentiated), intermediate malignancy and high malignancy (anaplastic). Depending on this differentiation, tumour cells may resemble mature fibroblasts (spindle-shaped), secreting collagen, with rare mitoses. These cells are arranged in short fascicles which split and ...
Histopathologic examination of the tumors in IMT generally reveals myofibroblastic spindle cell sheets in a myxoid background (i.e. a background matrix containing gelatinous mucopolysaccharides and non-sulfated glycosaminoglycans); the matrix also contains inflammatory cells, particularly plasma cells and lymphocytes occasionally mixed with ...
Hemangiopericytomas are tumors that are derived from specialized spindle shaped cells called pericytes, which line capillaries. [4] Hemangiopericytoma is an aggressive mesenchymally derived tumor with oval nuclei with scant cytoplasm. There is dense intercellular reticulin staining. Tumor cells can be fibroblastic, myxoid, or pericytic. These ...
