Regular screening and follow-up is highly recommended, as recurrence rates are higher Malignant osteoid differentiates from chondrosarcoma. Periosteal osteosarcoma is a distinct bone tumor entity with characteristic morphological features within the group of juxtacortical osteosarcoma. This page is about osteosarcoma pathology,contains pathology outlines,pathology outlines,pathology outlines,parosteal osteosarcoma and more Aims: The diagnosis of osteosarcoma, although important for eligibility in clinical trials and proper therapy, may be challenging when no bone or osteoid matrix is identified on biopsy. Therefore, other adjunct tests have been sought to help confirm the diagnosis. Special AT-rich sequence-binding protein 2 (SATB2) has been shown as a reliable marker of osteoblastic differentiation Giant cell-rich osteosarcoma (GCRO) is an uncommon variant that accounts for 1-3% of all cases of conventional osteosarcomas. Cytologically shows malignant cells associated with osteoid deposition. Abundant admixed benign osteoclast-like giant cells may obscure malignant features [1] Bone tumors are fortunately rare, but small cell tumors of bone are a relatively common subset of these lesions. They comprise of a diverse group of primary and metastatic neoplasms in both children and adults. The most common small cell tumors of bone include Ewing sarcoma/primitive neuroectodermal

Extraskeletal osteosarcomas are rare malignant mesenchymal neoplasms characterised by the direct production of osteoid or bone by tumour cells. By definition, they are located in the soft tissues without primary bone or periosteal involvement. The most common location of these tumours is the lower. Radiation-induced sarcomas can originate in either the irradiated bone or soft tissues. Most of these tumors are high-grade. The most common histologic subtypes are malignant fibrous histiocytoma (MFH) and osteosarcoma, although other histologies (eg, angiosarcoma, rhabdomyosarcoma) can occur. Tumor Osteosarcoma arising from cortical surface is classified into parosteal, periosteal and high-grade surface osteosarcoma. Along the spectrum, parosteal osteosarcoma occupies the well-differentiated end. It is a relatively rare disease entity, comprised only 4% of all osteosarcomas and barely reported in the literature. The objective of this study is to describe cases of parosteal osteosarcoma.

Soft tissue dedifferentiated leiomyosarcoma with heterologous osteosarcomatous component is an extremely rare entity described in only few cases in the literature.

Although bone cancers are rare, with annual age-adjusted rates of 1.0 per 100,000 for males and 0.6 per 100,000 for females, they are the third most frequently occurring type of malignancy among persons ages 10-24 years. 1 Among children (patients younger than 21 years), osteosarcoma accounts for approximately 60% of bone cancers, whereas Ewing's sarcomas account for 30%. Dedifferentiated chondrosarcoma consists of a low grade malignant hyaline cartilage tumor associated with a high-grade nonchondroid spindle sarcoma. The two components are juxtaposed with abrupt clear demarcation line. The high grade sarcoma is most commonly an MFH, osteosarcoma or fibrosarcoma although others may occur Usually osteosarcoma or chondrosarcoma ; Less commonly glioma, melanoma, rhabdomyosarcoma, angiosarcoma or liposarcoma ; Stroma may be composed of bland spindle cells (spindle cell carcinoma) p63 positive, often high molecular weight keratin positive ; May contain fibroblasts and or myofibroblasts; May resemble nodular fasciitis or fibromatosi Osteosarcoma is a frequent and extremely aggressive type of pediatric cancer. New therapeutic approaches are needed to improve the overall survival of osteosarcoma patients.
