Resumo

Neoplasias are important causes of illness and death in domestic animals. However, in birds, they are less frequent compared with other species such as dogs and cats. Moreover, benign tumors of bone are even less frequent in captive birds being considered sporadic, which make it a poorly understood entity due to the lack of clinical and histopathological data. Thus, we present a case of an osteoma in a Peach-faced lovebird (Agapornis roseicollis) approaching clinical and morphological aspects. A two-years-old lovebird was referred to the veterinary hospital with a 4-month evolution round to oval tumoral mass on the wing. The nodule was firm, painful when manipulated. Radiographic examination revealed a radiopaque mass in the radius and ulna bones. The animal has died during the surgical procedures. The affected wing was submitted to pathology service and histopathology revealed an osteoma.


As neoplasias são importantes causas de doença e morte em animais domésticos. No entanto, em aves, são menos frequentes em comparação com outras espécies, como cães e gatos. Além disso, tumores ósseos benignos são ainda menos frequentes em aves de cativeiro sendo considerados esporádicos, o que o torna uma entidade pouco compreendida devido à falta de dados clínicos e histopatológicos. Assim, apresentamos um caso de osteoma em Periquito cara-de-pêssego (Agapornis roseicollis) abordando aspectos clínicos e morfológicos. Um periquito de dois anos foi encaminhado ao hospital veterinário com uma massa tumoral ovalada na asa com evolução de 4 meses. O nódulo era firme, doloroso quando manipulado. O exame radiográfico revelou uma massa radiopaca nos ossos rádio e ulna. O animal morreu durante os procedimentos cirúrgicos. A asa afetada foi submetida ao serviço de patologia e a histopatologia revelou um osteoma.

Background: Calcinosis cutis is an uncommon dermatopathy characterized by the deposition of minerals in the skin,usually involving collagen and elastic fibers in the dermis. Usually, it results from dystrophic calcification and can begeneralized or focal. The dermatopathy may be primary or secondary to certain disorders, especially chronic proliferativeotitis, foreign body reactions, hyperadrenocorticism (HAC) and less frequently percutaneous penetration of calcium-richproducts. The aim of this report is to describe a presentation of calcinosis cutis affecting the skin of the back, internal faceof hind limbs and anal region of a 9-years-old bitch.Case: A 9-year-old, non-defined breed, bitch, ovariohysterectomized, weighing 9.45 kg, was attended at the DermatologicalService of companion animals at the Veterinary Hospital of the Federal University of Jataí (UFJ). The animal came in withthe complaint of extensive dorsal alopecia, covered by firm lesions, with a 3-month evolution, additionally to polyuria andpolydipsia. After physical examination, alopecic areas of great extension were confirmed on the dorsum, on the internalsurface of the hind limbs and in the anal region. Also, an exudative and painful lesion located on the back was detected,plus loss of elasticity of the ventral abdomen skin and visible abdominal vessels. The screening tests showed a markedincrease in the alanine aminotransferase enzyme (ALT), alkaline phosphatase (ALP) and total cholesterol. The specificurinary density was decreased. On the ultrasound examination, hepatomegaly and an increase in the caudal pole of the leftadrenal were detected. Based on these findings, calcinosis cutis secondary to spontaneous hyperadrenocorticism (HAC)was suspected. For confirmation, skin biopsy and low dose dexamethasone suppression test (LDDS) were performed.LDDS test showed no reduction of serum cortisol after 8 h of dexamethasone dose administration and histopathological...

Background: The nylon clamp, marketed as an accessory of electrical devices, has been used as an alternative method for definitive surgical hemostasis by ligature of arteriovenous vessels in ovariosalpingohisterectomy (OSH) in bitches and female cats. However, since May 2015, the Brazilian Veterinary Statutory Body (CFMV - Conselho Federal de Medicina Veterinária) banned its application, once it is a material still not regulated to be used in animals, in addition to the numerous reports of postoperative complications. This paper reports the migration of the clamp used in the OSH to the urinary bladder of the cat and the implications of the presence of the foreign body, in addition to discussing the use of this device in surgeries. Case: A 1-year-old Persian female cat, which, three months after an elective OSH in a private veterinary clinic, presented polyuria and hematuria. The patient presented pain at abdominal palpation; in the WBC were observed leucopenia and eosinophilia, indicating a chronic inflammatory process installed; the urinalysis showed the presence of crystals, increased urinary density, milky aspect indicating presence of pus, proteinuria and hematuria; on ultrasound were observed the presence of two amorphous mobile structures inside the bladder, producing acoustic shadow, measuring approximately 0.4 and 0.6 cm in diameter, suggesting the presence of bladder urolithiasis. Considering the results, the patient was sent for a cystotomy. The association of acepromazine (0.02 mg/kg), midazolam (0.2 mg/kg), morphine (0.2 mg/kg) and ketamine (10 mg/kg) was used intramuscularly as preanesthetic medication. For anesthetic induction, 5 mg/kg of propofol was applied intravenously, in addition to epidural anesthesia with 1 mL/4 kg of lidocaine along 0.1 mg/kg of morphine and, for maintenance, isoflurane in oxygen at 100%...
