In the literature, osteochondromas
represent 8% of rib tumors and half of benign rib tumors (1).
are easy to miss on the plain X-rays in pediatric population, unless specifically looked for.
In cats, osteochondromas
have been linked to feline leukemia virus (FeLV) infections (POOL & CARRIG, 1972; THOMPSON & POOL, 2002; ROSA & KIRBERGER, 2012).
Osteomas involving the condyler head can be difficult to differentiate from osteochondromas
, osteophytes or condyler hyperplasia on a plain radiograph and those involving coronoid may be similar to osteochondromas
Exostoses, Multiple Hereditary (MHE, HME), Osteochondromas
can be asymptomatic or cause symptoms like pain, radiculopathy/myelopathy, or cosmetic deformity [3-10].
may cause pain and a reduction in skeletal growth, bony deformity, restricted joint motion, shortened stature, premature osteoarthrosis, and the compression of peripheral nerves.
The neoplastic pathogenesis of solitary and multiple osteochondromas
occur as both multiple (hereditary multiple exostoses) and solitary lesions.
Human OSs are arising in irradiated bone, in bone affected by Paget's disease, and in skeletal tumors (multiple enchondromas, multiple osteochondromas
, fibrous dysplasia, and chondorsarcomas) (34, 35).
There have been approximately 100 cases in the literature of vascular complications due to osteochondromas
including pseudoaneurysm formation, occlusion, rupture or thrombosis.
Numerous bony excrescences resembling small osteophytes and osteochondromas
were seen in involved phalanges.
