Osteosarcoma with multiple metastases and subcutaneous involvement in a rabbit (Oryctolagus cuniculus)

Abstract

Clinical, radiologic, and pathologic data supported a diagnosis of osteosarcoma with multiple metastases and subcutaneous involvement.

Infiltrative Myxoma of the Stifle Joint and Thigh in a Domestic Rabbit (Oryctolagus cuniculus)

“…Metaplastic bone formation differentiates this tumour from osteosarcoma, which has been reported as an unusual spontaneous event in older rabbits (Mazzullo et al, 2004), where it may arise in long and flat bones (Hoover et al, 1986;Kondo et al, 2007), may metastasize (Walberg, 1981) and, most importantly, may cross joint spaces, resulting in a presentation similar to the present case (Kondo et al, 2007).…”

Cutaneous metastasis of primary appendicular osteosarcoma in a dog

“…[7][8][9][10][11][12][13][14][15] We are aware of only rare published case reports in animals, including primary bone OSA with cutaneous metastasis in a dog 4 and 2 rabbits with subcutaneous OSA attributed to presumed metastasis from primary bone OSA. 6,7 In the canine case, a 3-year-old, male Rottweiler was presented with multiple cutaneous metastases (sites unspecified) secondary to OSA in the distal left femur. Radiographic evidence of tumor invasion at other sites was not identified at the time of initial diagnosis; however, widespread metastatic disease was present at necropsy.…”

Characteristics of bone fractures and usefulness of micro–computed tomography for fracture detection in rabbits: 210 cases (2007–2013)

“…A few reports [13][14][15] of osteosarcoma in rabbits exist, but there has been only 1 report 16 of fractures attributed to metastases of uterine adenocarcinoma to bone tissue. A few reports [13][14][15] of osteosarcoma in rabbits exist, but there has been only 1 report 16 of fractures attributed to metastases of uterine adenocarcinoma to bone tissue.…”
