Primary bone tumors involving skull are extremely rare and they constitute 0.8% of all bone tumors. The common tumors that are seen in skull base include fibrous dysplasia, giant cell tumor, chordoma, ossifying fibroma, angiosarcoma. We report a rare case of spindle cell sarcoma arising from right sphenoid bone in a 70-year-old male which presented as unilateral defective vision with mild proptosis.

Primary Bone

Spindle cell sarcoma (SCS) is a rare malignant tumour which can arise in bone and accounts for 2%–5% of primary bone cancer cases. Distant metastasis occurs predominantly in the lungs. However, metastasis to the soft palate, to the best of our knowledge, has never been previously reported. In this case report, we describe a unique presentation of soft palate metastasis in a patient with a history of high-grade SCS of the bone who presented with progressive dysphagia and nausea and vomiting who underwent surgical excision for palliation of symptoms.

Primary Bone

Rare primary malignant bone sarcomas (RPMBS), other than osteosarcoma, chondrosarcoma, chordoma, and Ewing sarcoma, account for about 5–10% of primary bone tumors and represent a major diagnostic challenge. These tumors include spindle cell and round cell sarcoma entities, hemangiopericytoma-like and vascular tumors. Additionally, several histotypes, traditionally described in the soft tissues, such as myxofibrosarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumor of bone, have been reported in patients with primary bone tumors. While wide surgical resection is the mainstay of local treatment, systemic therapy of these rare entities is controversial. Patients with undifferentiated spindle cell or pleomorphic high-grade tumors of bone, are usually treated with osteosarcoma-like chemotherapy, while patients with round cell and undifferentiated round cell tumors (URCTs), may respond to sarcoma treatment regimens for Ewing sarcoma patients. Studies on analogies and differences among these ultra-rare tumors have seldom been reported. This review describes relevance, clinical aspects, diagnostic procedures, staging, treatment recommendations, and current research in this composite tumor group.

A review of 12 cases of bony tumors involving the talus is presented. Giant cell tumor was the most common tumor. Malignant tumors should be treated by surgical ablation followed by chemotherapy. There are good results after excision or curettage and bone grafting in the treatment of benign neoplasms. Giant cell tumors, if diagnosed early, can be treated by curettage and bone grafting, but if there is talar collapse, a talectomy can be performed.

With the extensive industrial use of asbestos in this century and the long latent period (20-50 years) between exposure and tumor presentation, the incidence of malignant mesothelioma is now increasing. Thus, surgical pathologists are more frequently faced with the dilemma of differentiating mesothelioma from metastatic adenocarcinoma and spindle-cell sarcoma involving serosal surfaces. Electron microscopy is amodality useful in clarifying this problem.In utilizing ultrastructural features in the diagnosis of mesothelioma, it is essential to appreciate that the classification of this tumor reflects a variety of morphologic forms of differing biologic behavior (Table 1). Furthermore, with the variable histology and degree of differentiation in mesotheliomas it might be expected that the ultrastructure of such tumors also reflects a range of cytological features. Such is the case.

Whole-body scintigraphy with both 99mTc-phosphonate and 67Ga was performed on 92 patients suspected of primary bone tumors. In 46 patients with primary malignant bone tumors, scintigraphy with 99mTc-phosphonate disclosed the primary tumor in 44 cases and skeletal metastases in 11, and 67Ga scintigraphy detected the primary tumor in 43 cases, skeletal metastases in 6 cases and soft-tissue metastases in 8 cases. In 25 patients with secondary malignant bone tumors, bone scintigraphy visualized a single lesion in 10 cases and several lesions in 15 cases, and 67Ga scintigraphy detected the primary tumor in 17 cases, skeletal metastases in 17 cases and soft-tissue metastases in 9 cases. In 21 patients with benign bone disease positive uptake of 99mTc-phosphonate was recognized in 19 cases and uptake of 67Ga in 17 cases. It is concluded that bone scintigraphy should be used in patients suspected of primary bone tumors. If malignancy is suspected, 67Ga scintigraphy should be performed in addition.

A review of the literature shows that surgical procedures will remain the standard treatment for primary bone tumors. Analysis of studies on the assessment of long-term results shows that additional double cryogenic treatment of the curettage cavity can improve the treatment outcomes of patients with giant cell tumors, dysplastic diseases and some forms of malignant lesions. The traditional execution of the procedure is associated with the open installation of liquid nitrogen in the bone cavity, which requires special skills in handling aggressive refrigerant from the staff and does not exclude complications. In case of multiple metastatic bone lesions, surgical treatment is not indicated. The recent emergence in clinical practice of new equipment with a closed liquid nitrogen circulation circuit inside cryoprobes resumes interest in cryoabla-tion of bone tumor lesions using modern minimally invasive puncture cryotechnology and expanding indications for its use in patients with severe comorbidities.
