Clear cell chondrosarcoma of the talus in Von Hippel-Lindau disease: a rare tumor in an unusual location and uncommon co-presentation.

Clear cell chondrosarcoma of the talus in Von Hippel-Lindau disease: a rare tumor in an unusual location and uncommon co-presentation. Int J Clin Exp Pathol. 2020;13(2):266-271 Authors: Song MJ, Won KY, Park S Abstract Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited tumor syndrome. Clear cell chondrosarcoma (CCCS) is a rare variant of chondrosarcoma. Here, we report a case of CCCS in the talus occurring in a patient with VHL disease. A 32-year-old man presented with ankle pain for 2 years. MRI revealed a 4.2 cm mass in the talus, and needle biopsy was performed. The patient underwent curettage but the final diagnosis was CCCS. Adjuvant radiation therapy was performed without additional talectomy and the patient was alive without recurrence for a follow-up period of 2 years. To our knowledge, this is the first case in the English medical literature of a co-presentation of this rare disease and condition: i.e. CCCS with VHL disease in the unusual location of the talus. We cautiously suggest that CCCS may be associated with VHL disease based on their histologic similarity. PMID: 32211108 [PubMed]

Conclusion: Intrathecal dexmedetomidine is more efficacious as compared to intravenous dexmedetomidine, due to favourable outcomes in terms of increased duration of postoperative analgesia and reduced rescue analgesic requirement.

Conclusions: The proposed nomogram is a reliable and robust tool for accurate prognostic prediction in patients with extremity soft tissue LMS. Introduction Soft tissue leiomyosarcoma (LMS) is an aggressive sarcoma, which originates from smooth muscle cells (1). Soft tissue LMS accounts for about 5–10% of all soft tissue sarcomas (2). It occurs in different sites, including the retroperitoneum, intraabdominal sites, and extremities (3). Extremity LMS comprised about 10–15% of extremity sarcomas, with a preference for the lower limb (4–6). Extremity LMS tends to have a better prognosis than uterine...

Conclusions: Our findings reassure that malignant transformation of enchodromatosis of the hand is unlikely in the pediatric population. Pathologic fracture is common, but has excellent outcomes. When considering surgery, parents should be counseled about the possibility of phalangeal growth arrest and recurrence of the lesion. Type of Study/Level of Evidence: Level IV—therapeutic.

The infrapatellar fat pad (IFP) also known as Hoffa fat pad, an intracapsular extrasynovial structure readily visualized on magnetic resonance imaging of the knee,1 can be affected by a variety of pathologic conditions (lipoma, hemangioma, synovial chondromatosis, focal villonodular synovitis, ganglion cyst, osteochondroma, and chondrosarcoma).2 Because synovial hemangioma is an extremely rare disease and often shows nonspecific symptoms (pain, swelling, limping, or limitation of motion), diagnosis could be delayed in many cases.
