Intermuscular Lipoma in Dogs

ABSTRACT

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 classified as intermuscular lipomas. Complete surgical resection of the tumor mass is indicated as a treatment of affected patients.This report describes five 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 first 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 cytology (FNAC) was performed and showed cells from adipose tissue, followed by histopathological examination of the lesions. Histopathological examination after incisional biopsy of the tumors showed malignancy-free tissue, composed of adipocytes without atypia, interspersed with fibrovascular stroma, confirming the lipoma diagnosis. Intermuscular lipomas were diagnosed in five dogs with a history of a [...]
