Abstract Context.—Hyalinizing spindle cell tumor with giant rosettes is a recently described biphasic neoplasm of soft tissues that shares mesenchymal and neuroendocrine features. Its morphologic structure is distinctive, with the presence of hyalinized paucicellular foci that are termed rosettes. The cells around the latter display positive immunoreactivity for neuroendocrine markers. The small number of cases described to date indicates that they tend to be localized in the extremities. Objective.—To describe the clinicopathologic features of 2 unusual cases of hyalinizing spindle cell tumor with giant rosettes. Methods and Results.—One tumor was located in the prestyloid parapharyngeal space and the second in the left thigh. Both tumors were well circumscribed and surrounded by a thin capsulelike fibrous band without infiltrating projections. The rosettes were embedded in a spindle cell proliferation. Immunohistochemical stains showed positive results for S100 protein, synaptophysin, CD57, protein gene product 9.5, and neuron-specific enolase exclusively in the cells palisading the rosettes. These markers were negative in the spindle cell portions of the tumor. The latter were immunoreactive for factor XIIIa, vimentin, HAM56, collagen IV, and CD68. Vimentin was the only marker shared by the rosette-forming cells and the spindle cells. Ultrastructurally, the rosette-forming cells contained neurosecretory granules. This study describes the first cytogenetic analysis in this type of tumor revealing 2 cell lines, both containing a balanced translocation between chromosomes 7 and 16. Follow-up of the patients at 16 and 8 months did not disclose evidence of recurrence. Conclusions.—These 2 new cases increase the awareness of hyalinizing spindle cell tumor with giant rosettes and demonstrate that it is a spindle cell neoplasm of unique cytogenetic rearrangements composed of dendritic, histiocytic, and fibroblastic cells admixed with cells that have neuroendocrine differentiation.

✓The purpose of this report is to demonstrate that synovial sarcoma should be included in the differential diagnosis of tumors originating from the lumbar spine, especially if they show hemangiopericytoma-like pathological characteristics. A synovial sarcoma is a mesenchymal spindle cell tumor that displays variable epithelial differentiation including glandular formation. It is unrelated to a synovium. More than 80% of these lesions arise in the deep soft tissue of the extremities. The tumor frequently arises adjacent to joints or tendon sheaths. The authors describe a young woman with a hemangiopericytoma-like tumor of the lumbar spine. During repeated operation, this lesion was shown to be a synovial sarcoma, which had invaded the dura mater. The tumor metastasized to the mediastinum and the intradural cervical spine and, finally, to the brain and the lungs. To the authors’ knowledge, this is the first reported case of a synovial sarcoma originating from the lumbar spine.

Primary hydatid disease of musculoskeletal system is rare. A 46 year old man presented with soft swelling in anterior aspect of thigh of two years duration which was gradually increasing in size. He was initially diagnosed as malignant spindle cell tumor of thigh, but ultrasonography and Commuted Tomography Scan revealed to be a cystic swelling suggestive of hydatid disease. Our patient had not been operated for hydatid disease previously and investigations did not reveal any hydatid cyst in liver, lung or spleen. So our patient was diagnosed having primary hydatid disease of musculoskeletal system. Serologic test (ELISA) was negative. Patient was given albendazole preoperatively. A careful management is required to prevent systemic dissemination and anaphylactic shock. The swelling was removed en bloc without causing damage to cyst wall and advised for adjunctive albendazole chemotherapy (15 mg/kg/day) for three months.Bangladesh Journal of Medical Science Vol.15(4) 2016 p.628-630
