Giant chondrosarcoma of the falx in an adolescent: A case report

Background: Intracranial chondrosarcomas are slowly growing malignant cartilaginous tumors that are especially rare in adolescents. Case Description: A 19-year-old woman with no medical history presented with symptoms of intermittent facial twitching and progressive generalized weakness for 6 months. The patient’s physical examination was unremarkable. Imaging revealed a large bifrontal mass arising from the falx cerebri, with significant compression of both cerebral hemispheres and downward displacement of the corpus callosum. The patient underwent a bifrontal craniotomy for gross total resection of tumor. Neuropathologic examination revealed a bland cartilaginous lesion most consistent with low-grade chondrosarcoma. Her postoperative course was uneventful, and she was discharged to home on postoperative day 3. Conclusion: This is an unusual case of an extra-axial, non-skull base, low-grade chondrosarcoma presenting as facial spasm in an adolescent patient.

Ankle Synovial Chondromatosis: case report of 2 cases with 139 and 12 lose bodies treated arthroscopically

Synovial chondromatosis is an uncommon, benign neoplastic nodular cartilaginous lesion of the synovium that can lead to lose bodies and arthritic degeneration if left untreated. We report the case of 2 patients with primary Synovial chondromatosis of the ankle with 139 and 12 loose bodies, respectively, who were treated arthroscopically. Both patients had successful outcomes without recurrence or malignancy, after excision of the lesions. We have reported the highest number of loose bodies (i.e. 139) in the ankle extracted arthroscopically. To conclude, Synovial chondromatosis, although benign, needs detailed investigations to rule out secondary causes and timely intervention to prevent further consequences. Arthroscopic treatment provides easy access and allows early return to activities. Level of clinical evidence: 4- Case Report.

Chondroblastoma of the Talus Treated with Osteochondral Autograft Transfer from the Lateral Femoral Condyle

Chondroblastoma is a benign cartilaginous lesion of bone. When occurring in a position juxtaposed to articular cartilage, treatment is directed at removal of the tumor with preservation of the articular cartilage. In this case, a chondroblastoma of the talus with erosion into the articular cartilage was treated with transfer of an osteochondral autograft from the ipsilateral femoral condyle. At two-year follow-up, the patient was symptom free and magnetic resonance imaging revealed complete incorporation of the graft. This case is presented as a representative example of osteochondral autograft transfer surgery (OATS) for the treatment of chondroblastoma.

Cartilaginous Tumors of the Larynx

Cartilaginous tumors of the larynx, while rare, will on occasion be encountered by the otolaryngologist in routine daily practice. True laryngeal chondromas are exceedingly rare, and as a consequence, a putative diagnosis of chondroma should be viewed with suspicion. On pathologic examination, laryngeal chondromas usually prove to be small lesions (less than 2 cm in maximum dimension) and may arise in children or adults. Laryngeal chondrosarcomas, by contrast, usually prove to be larger lesions (exceeding 3 cm in greatest dimension) and are typically found in adults. While high-grade chondrosarcomas are readily identifiable on light microscopic study, the distinction between a chondroma and a low-grade chondrosarcoma is often not so clear-cut. Some low-grade chondrosarcomas may show a slight increase in both cellularity and cytologic atypia when compared with chondromas, but the two patterns often overlap. When faced with a limited biopsy specimen of a laryngeal cartilaginous lesion in which neither increased cellularity nor recognizable cytologic atypia is found, a diagnosis of “cartilaginous tumor without obvious evidence of malignancy — further classification dependent on examination of the lesion in its entirety,” or words to this effect, is recommended.
