[PMID: 37705036 PMCID: PMC10498572 DOI: 10.1186/s13000-023-01390-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Accepted: 09/03/2023] [Indexed: 09/15/2023] Open
Abstract
BACKGROUND Extraskeletal myxoid chondrosarcoma (EMC) is a rare malignant tumor described in the head and neck region, especially in the gingival. We present one case arising in the gingival of right mandible, and briefly reviewed the related literature. CASE PRESENTATION A 24-year-old male patient with a lesion of 3.5*2.0 cm in buccal gingival of right posterior mandible for 2 months. The tumor was composed of cartilaginous structures and myxoid matrix. Immunohistochemical(IHC) showed that the tumor cells to be positive for vimentin, focally positive for S-100, negative for calponin, SMA, SOX10. The Ki-67 labelling index was 80%. Fluorescent in situ Hybridization (FISH) was positive for NR4A3 rearrangement. CONCLUSIONS Due to its unusual site and low incidence in the oral region, a combination of histological findings, immunohistochemistry, and molecular pathology as well as differential diagnosis with other diseases should be taken into consideration in the process of clinical diagnosis and treatment.

[PMID: 36538608 DOI: 10.1002/jmor.21550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 12/11/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022]
Abstract
While the occurrence of skeletal pathologies in Middle Triassic marine reptiles has been poorly documented until now, massive accumulations of bone remains from the Germanic Basin provide the opportunities for documentation. Herein, we describe skeletal abnormalities in the Middle Triassic bone material from the Vossenveld Formation of Winterswijk, the Netherlands. The aim of the study is to distinguish in the studied bones pathologies resulting from malady or trauma and taphonomic alterations. Furthermore, an attempt was made to assess on how the pathologies also represent paleoecological data. Our survey led to the identification of one broken and healed bone, one case of abnormal coossification, and one case of posttraumatic fibro-osseous dysplasia. While the latter two pathologies give little insight into the ecology and function of the affected animals, the fractured dentary is attributed to Nothosaurus marchicus, a common sauropterygian macropredator. It proves that the individual survived long enough to heal, despite the injury hampering its hunting potential. One abnormally shaped humerus is interpreted as postmortem taphonomic deformation, emphasizing the necessity of utilization of detailed diagnostics to distinguish actual paleopathologies from nonbiological distortion.

Abstract
BACKGROUND Chondromyxoid fibroma (CMF) is an unusual benign tumour of cartilaginous tissues that may be confused with other malignant tumours. It is rarely seen in the cervical spine.
CASE SUMMARY A 24-year-old young woman was admitted to the hospital because of neck and shoulder pain. Computed tomography, magnetic resonance imaging, X-ray and other imaging examinations of the cervical spine and laboratory-related indicators combined with intraoperative pathology revealed that the patient had cervical CMF. We performed total resection of the vertebral body and intervertebral disc, and internal fixation was performed to simultaneously maintain the stability of the entire spine. The clinical results from extensive resection were satisfactory. At the 2-year follow-up, the patient's symptoms had not recurred.
CONCLUSION CMF is a benign primary bone tumour that is rarely located in the vertebral bone. Accurate initial diagnosis of these tumours is important for appropriate treatment. En bloc surgical resection of the tumour is the cornerstone of treatment.
