Mast cells and tumor angiogenesis
International Journal of Cancer, 1976AbstractTumor angiogenesis factor (TAF) elicits a strong vasoproliferative response when implanted upon the chorioallantoic membrane (CAM) of the chick embryo. This response is first observed stereomicroscopically 2–3 days after implantation. A 40‐fold increase in mast cell density is observed within the vicinity of this implant by 24 h.

Mast Cells in the Tumor Microenvironment
2020Mast cells are tissue-resident, innate immune cells that play a key role in the inflammatory response and tissue homeostasis. Mast cells accumulate in the tumor stroma of different human cancer types, and increased mast cell density has been associated to either good or poor prognosis, depending on the tumor type and stage.

Veterinary Clinics of North America: Small Animal Practice, 1990
Mast cell tumors (MCTs) are common in the dog, occurring most frequently in the skin and subcutaneous tissues. Their biologic behavior can be quite variable, with approximately 50% being malignant. Although clinical features and histologic grading can help determine the likelihood of malignancy, it is difficult to predict the biologic behavior of an ...

Veterinary Clinics of North America: Small Animal Practice, 1985
Despite the fact that the mast cell tumor is a common neoplasm of the dog, we still have only a meager understanding of its etiology and biologic behavior. Many of the published recommendations for treatment are based on opinion rather than facts derived from careful studies and should be viewed with some skepticism.

Mast cell tumors in three ferrets
Journal of the American Veterinary Medical Association, 1990Pruritic open skin lesions (5 mm diameter) on the thorax, neck, or head of 3 ferrets were diagnosed as mast cell tumors. Diagnosis of the tumors was based on histologic examination of biopsy specimens. Histologic diagnosis was necessary because the lesions had been treated as mycotic or bacterial ulcers and did not respond to conventional treatment ...

Extracutaneous Mast-Cell Tumor in the Dog
Veterinary Pathology, 1982Three neoplasms of extracutaneous mast-cell origin, arising from the nasopharynx, oral cavity, and hepatopancreatic lymph nodes respectively, were diagnosed in three dogs. The neoplasms had histologic features similar to those of cutaneous mast-cell tumors, but had limited metastasis mostly involving the regional lymph nodes.

Ureteral Mast Cell Tumor in a Dog
Journal of the American Animal Hospital Association, 2004A 6-year-old, castrated male, mixed-breed dog was diagnosed with partial unilateral ureteral obstruction secondary to a ureteral mass. The ureteral mass was surgically resected, and an ureteroneocystostomy was performed. Histopathology of the ureteral mass was consistent with a poorly differentiated mast cell tumor (MCT). The patient recovered well but

Spinal Mast Cell Tumor in a Dog
Journal of the American Animal Hospital Association, 2002A 6-year-old, spayed female rottweiler was referred for left forelimb lameness followed by tetraparesis. A mast cell tumor compressing the spinal cord at the level of the sixth cervical to first thoracic (C 6 –T 1 ) vertebrae was diagnosed based on ...

Principles of treatment for mast cell tumors
Clinical Techniques in Small Animal Practice, 2003Mast cell tumors (MCT) are the most common malignant cutaneous tumors that occur in dogs. They are most commonly found on the trunk, accounting for approximately 50% to 60% of all sites. MCTs associated with the limbs account for approximately 25% of all sites. Cutaneous MCTs have a wide variety of clinical appearances.

Mast Cell Response To Tumor Graft
1988The association of mast cells (MC) with tumor tissue has been frequently reported since the first description of these cells by Ehrlich (1).Mast cells were found in abundance at the periphery of carcinogen-induced tumor as well as of transplanted fibrosarcoma (2–4).
