ULTRASONOGRAPHIC FEATURES OF CANINE LIPOMAS
Veterinary Radiology & Ultrasound, 2006
The purpose of this study was to evaluate the ultrasonographic features of canine lipomas. A group of 94 dogs with a soft tissue mass was considered. All dogs were examined ultrasonographically and cyto/histologic examination was performed. Twenty-four dogs, whose mass was diagnosed as a lipoma, were selected. Fifty-five lipomas were present on the 24 dogs. Fifty-one lipomas were superficial and located subcutaneously. Four lipomas were deep and located in the paratesticular region. Ultrasonographically, lipomas appeared as oval, well-defined, encapsulated, striated masses.

Background : Lipoma is a benign tumor composed of mature adipose tissue commonly found in subcutaneous tissues. However, eventually, lipomas may be located between the muscle fasciae being classifed as intermuscular lipomas. Complete surgical resection of the tumor mass is indicated as a treatment of affected patients.This report describes fve cases of intermuscular lipoma in dogs, due to the scarcity of data in the literature and lipoma relative importance in the clinical and surgical routine. Case : Five dogs were presented with a history of a large volume in the limbs with progressive growth, suggesting the presence of neoplasia. The frst step was to conduct anamnesis, when the owner reported slow growth, absence of pain, limping and licking of site. No other change was observed upon physical examination. Complete blood count (CBC) as well as liver assessment (FA) and renal (creatinine) were performed in all patients, and the results showed no changes. Fine needle aspiration cyto...
Liposarcomas in dogs: 56 cases (1989–2000)
Journal of the American Veterinary Medical Association, 2004
Objective—To determine the biological behavior of liposarcomas in dogs and identify clinical signs, the effect of treatment on survival time, and potential prognostic factors. Design—Retrospective study. Animals—56 dogs with histologically confirmed liposarcoma. Procedure—Information was obtained on signalment, tumor size, location of the tumor, stage of disease, remission duration, overall survival time, cause of death, type of surgery (incisional biopsy, marginal excision, or wide excision), and any additional treatments given. Results—Surgery consisted of incisional biopsy in 6 dogs, marginal excision in 34, and wide excision in 16. Twenty-five dogs had histologic evidence of tumor cells at the surgical margins and 28 did not (status of the margins was unknown in 3 dogs). Twelve of 43 dogs had local recurrence. Median survival time was 694 days, and the only factor significantly associated with survival time was type of surgery performed. Median survival times were 1,188, 649, an...
Canine lipomas treated with steroid injections: clinical findings
Lipomas are common benign tumours of fat cells. In most cases, surgical excision is curative and simple to perform; however, such a procedure requires general anaesthesia and may be associated with delayed wound healing, seroma formation and nerve injury in deep and intramuscular tumours. The objective of this study was to evaluate treatment of subcutaneous, subfascial or intermuscular lipomas using intralesional steroid injections in dogs. Fifteen dogs presenting with lipomas were selected for treatment with ultrasound-guided intralesional injection of triamcinolone acetonide at a dose of 40 mg/mL. Nine subcutaneous and subfascial tumours showed a complete regression. The other lipomas decreased in diameter, achieving, in some cases, remission of discomfort and regression of lameness. Steroid injection was a relatively safe and effective treatment for lipomas in dogs; only six dogs experienced polyuria/polydipsia for about 2 weeks posttreatment.

Benign intrapericardial lipoma in a dog
Journal of Veterinary Cardiology, 2002
Canine lipomas generally develop in subcutaneous tissue. Intrapericardial lipomas are extremely rare benign tumours and can develop on the pericardial surface of the heart or inside the cardiac chambers. As the thoracic cavity is an unusual site for lipomas in dogs, we describe, clinically and pathologically, a case of intrapericardial lipoma in an 18months old German Shepherd
Infiltrative lipoma compressing the spinal cord in 2 large-breed dogs
The Canadian veterinary journal. La revue vétérinaire canadienne, 2013
Two cases of infiltrative lipomas compressing the spinal cord and causing nonambulatory paraparesis in 2 large-breed dogs are reported. Magnetic resonance imaging (MRI) revealed severe extradural spinal cord compression by inhomogenous masses that infiltrated the adjacent tissues and the muscles of the spine in both dogs. The presumptive clinical diagnoses were infiltrative lipomas, which were confirmed by histopathology. In rare cases infiltrative lipomas are able to compress the spinal cord by the agressive growth of invasive adipocytes causing neurological deficits.
Suspected intrapericardial lipoma in a standard schnauzer
Veterinary Record Case Reports
A five-year-old, male, neutered standard schnauzer presented for vomiting, diarrhoea and fever. A large intrapericardial fatty mass was identified on advanced imaging. The patient underwent a median sternotomy and exploratory coeliotomy to remove the fatty mass measuring 100 mm x 76 mm x 66 mm, the histopathology of which revealed a large fatty mass with necrosis and inflammation. This is the largest reported intrapericardial fatty mass in the veterinary literature. CT at 28 weeks postoperatively revealed no evidence of recurrence.
Liposarcoma with perineal hernia in dog
Revista Brasileira de Ciência Veterinária, 2014
Liposarcoma is an uncommon malignant tumor originated in the lipoblasts that usually does not produce metastases, but is locally invasive. The final diagnosis is made by histopathology and wide surgical excision is the treatment. A four years old male Pinscher, weighing 2.8 kg, which was previously submitted to seven therapeutic procedures for hepatoid adenoma, was brought to us. On clinical examination a large, soft consistency and painless tumor on lumbodorsal area, besides perineal hernia, was observed. The CT scan revealed an image of an extensive paravertebral intramuscular tumor, embracing retroperitoneal, pelvic canal and ad-anal region. After surgical resection, the material was sent for histopathological examination which confirmed it was a liposarcoma. Thus, chemotherapy protocol with doxorubicin was established. 12 months after the last application of chemotherapy, the patient shows no signs of tumor recurrence nor metastases.
