A Rare Case of Extraskeletal Mesenchymal Chondrosarcoma with Dedifferentiation Arising from the Buccal Space in a Young Male

Extraskeletal mesenchymal chondrosarcoma (ESMC) originate from the nasal cavity have rarely been reported, especially its imaging features, which makes the preoperative diagnosis difficult. Here, we report the clinical, computed tomography, and magnetic resonance imaging features of a 60-year-old female patient with pathologically confirmed ESMC in the nasal cavity to help provide more reference for diagnosis before operation. Extraskeletal mesenchymal chondrosarcoma in the nasal cavity demonstrates typical imaging features, such as mesh-like enhancement, calcification, hemorrhage, necrosis, cystic degeneration, and so on.

Extraskeletal Mesenchymal Chondrosarcoma

AbstractExtraskeletal mesenchymal chondrosarcoma (ESMC) metastasizing to the pancreas in isolation is a rare occurrence. We report a 49-year-old gentleman who had undergone excision of an ESMC of the thigh in 2009 and presented with sudden onset abdominal pain and icterus in 2019. Radiological imaging revealed calcified mass of the pancreas with multiple nodules with extension into the adipose tissue. Distal pancreatectomy was performed and the pathology revealed a bimorphic tumor composed of undifferentiated round blue cells with abrupt transition to hyaline cartilage, typical of mesenchymal chondrosarcoma. To the best of our knowledge, there are only seven prior cases of metastatic ESMC of the pancreas in the English literature. Surgical intervention appears to be the preferred modality of treatment for metastatic pancreatic tumors. These patients may have long latency period before metastasizing and seem to have a good survival period post excision.

Extraskeletal Mesenchymal Chondrosarcoma

Extraskeletal mesenchymal chondrosarcoma is a rare soft tissue sarcoma arising from soft tissues, mainly of the lower extremities, meninges, and orbits. It usually presents during the second to third decades of life, and has a slight predominance in females. Histologically, it has a typical biphasic pattern comprising small cells and islands of hyaline cartilage. It can pose a diagnostic challenge in small biopsy specimens where 1 of the 2 components can be absent. The prognosis is extremely variable; survival varies depending on the location of the tumor.
