“…10 It is often associated with tendons, tendon sheath or joint capsule 11 ; unlike periosteal chondroma, it is located outside the periosteum. 12,13 Extra skeletal chondroma usually manifest as slowly enlarging nodule. Tumour mainly affects adults 30 to 60 years of age and is rare in children.…”

“…Chondromas are rare, benign tumors composed of cartilaginous tissue that mainly affect the metaphases of long tubular bones, especially the proximal humerus and distal femur [1-2]. These tumors are categorized as juxtacortical (periosteal) chondromas that arise from the surface of periosteum, enchondromas that arise from within the bone marrow or enchondromatosis, which is a form of osteochondrodysplasia characterized by a proliferation of enchondromas.…”

Chondromas are rare, benign tumors composed of cartilaginous tissue that mainly affect the metaphases of long tubular bones. Juxtacortical (periosteal) chondromas arise from the surface of periosteum and rarely affect the cervical spine. We present a patient with a spinal juxtacortical chondroma causing spinal cord compression and a cervical deformity treated with surgical resection and circumferential spinal fixation and stabilization. A 55-year-old female with past medical history of Crohn’s disease with years of neck pain, balance issues, and left upper extremity radicular symptoms. Cervical spine x-rays show kyphosis with an apex at C5, degenerative changes of the endplates and facet joints, and grade 2 anterolisthesis C4 on C5 with no abnormal motion with flexion/extension. MRI showed a left sided C5-6 extramedullary mass measuring 11 x 11 x 15 mm causing spinal cord compression and neural foraminal narrowing. Her pain is worsening and refractory to physical therapy, gabapentin and methocarbamol. A C4-5 & C5-6 anterior cervical discectomy and fusion, C4-5 & C5-6 laminectomy for tumor resection, and C4-5 & C5-6 posterior fusion with instrumentation was performed. The tumor was completely removed in piecemeal fashion. Microscopic findings showed bland well differentiated cartilaginous neoplasm consistent with juxtacortical chondroma. Postoperative X-rays show partial reduction of C4-5 anterolisthesis and partial reversal of cervical kyphosis. The patient’s radicular pain resolved and neck pain improved postoperatively but she still has some left sided neck pain and hand dysesthesias that are controlled with oral medication one year following surgery. Cervical chondromas are rare, benign cartilaginous tumors that may present with spinal cord or nerve root compression. They are more complex when they present in patients with co-existing spinal deformities. Maximal safe resection followed by spinal re-alignment and fixation without adjuvant chemotherapy or radiation is recommended in most cases. Close follow-up is recommended to monitor for recurrence.

Differential diagnosis of an unusual tibial pathology from Peru

During an osteological analysis of human skeletal remains from the site of Punta Lobos (Huarmey Valley, northern coastal Peru), an unusual erosive lesion of the cortex with periosteal reaction was observed on a right tibia. The authors undertook a review of paleopathological and medical literature to arrive at a differential diagnosis. The lesion is determined to be a non-malignant growth, possibly a large periosteal ganglion, though a diagnosis of periosteal chondroma (a benign neoplasm) or other uncommon neoplasm could not be definitively ruled out.
