A two-year-old queen was referred to the surgery section of veterinary hospital with lateral recumbency position and the primary diagnosis of dystocia. The queen was highly lethargic and dehydrated, with a pale mucous membrane, a rectal temperature of 37.3 °C, and no vaginal discharge during first inspection. The primary examination revealed a big mass in the abdominal cavity, which was followed by other diagnostic investigations. Due to a huge and encroaching tumor and the patient's owner's refusal to accept any further therapies, the queen was euthanized during an exploratory celiotomy. This report describes a large Hemangiopericytoma (HPCy) in a domestic short-haired queen diagnosed based on physical examination, radiography, ultrasonography, histomorphology, and immunohistochemical reactivity. The results of pathology revealed a whorls around blood vessels and the "fingerprint" pattern of tumor with negative S-100 immunohistochemistry staining.   In dogs, HPCy is a common neoplasm, but it is a seldom finding in cats. There is no previous report of HPCy in the abdominal cavity as observed in the presented case to the authors' knowledge.

As the number of large-scale dairy farms increase dairy cow welfare has become a hot topic in recent years. This growing interest in animal welfare has motivated legislators to set new rules. The most important concerns regarding dairy cow welfare include whether the dairy cow is feeling well, functioning well, and performing natural behavior. Cow behavior and comfort level have a direct relationship with her production and health and cow comfort is one of the most important factors affecting the profitability of dairy farms due to its association with premature slaughter, survival of cows and reproductive life (number of complete lactations before slaughter). In this paper, we explained the concept of comfort in dairy cattle and its risk factors such as stall design, floor type, density, lameness and heat stress. Then the measures of cow comfort are introduced and the management considerations related to cattle comfort are discussed.
