Abstract: Low grade central osteosarcoma is a rare primary bone tumor. This fibro-osseous lesion shares some radiological and histopathological resemblance with fibrous dysplasia, which is a more common entity. Thus it may be mistaken as fibrous dysplasia and may receive inadequate treatment resulting in a more malignant recurrent bone tumor. We present a case of low grade central osteosarcoma of the right tibia, which was initially treated as fibrous dysplasia with curettage and bone grafting. Three years later the tumor recurred with greater soft tissue and bony involvement but without metastasis. The patient was treated with above knee amputation and has been asymptomatic for the last two years. [Copyright &y& Elsevier]

Abstract: Kimura''s disease is a rare, chronic inflammatory disorder, presenting usually as head and neck swellings and regional cervical lymphadenopathy. The disease is more often described from oriental literature but the osseous manifestations and involvement of extremity are rare and unidentified in literature. We present an unusual case of long bone periosteal reaction in a patient of Kimura''s disease of extremity. This potentially innocuous disorder must be kept in mind as a radiological differential of periosteal reaction. [Copyright &y& Elsevier]

Abstract: Desmoplastic fibroma of bone is an extremely rare locally aggressive primary bone tumour. Diagnosis is tricky and treatment experience limited with tumor surgeons. We studied three rare cases of desmoplastic fibroma arising primarily in bone at unusual sites. Diagnosis was established by radio-histopathologic correlation. Patients were operated with various modalities. Results were evaluated over long term follow-up (6–9years). The disease was eradicated in all the three cases and no recurrence was seen over long term follow-up. Functional outcome was good and no complications were encountered. Wide resection of the tumor is favoured as the recurrence rates after surgical treatment are high. [Copyright &y& Elsevier]

Abstract: Spinal tuberculosis constitutes 50% of all musculoskeletal tuberculosis. However, literature regarding congenital spinal tuberculosis is very scanty. Congenital spinal tuberculosis was diagnosed in a two-month-old child on the basis of age at presentation (gibbus since three weeks of age), hepatomegaly, raised ESR, radiological destruction of D10–D11 vertebrae, asymptomatic maternal endometrial tuberculosis and tuberculous histopathology from CT guided biopsy specimen from D10 vertebra. Both child and mother were treated by antitubercular treatment. Child improved symptomatically, gibbus became less prominent and ESR became normal at the end of one year of treatment. Patient had no recurrence during last two years of follow-up. This is the first case of congenital tuberculosis of spine with a documented source of infection from asymptomatic maternal endometrial tuberculosis. CT guided core biopsy from vertebra/aspiration from the paravertebral abscess help in early diagnosis and treatment to reduce neurological morbidity and mortality. Endometrial biopsy help in establishing the diagnosis of congenital tuberculosis and adequate antitubercular treatment in such cases may provide protection to fetus in subsequent pregnancy.
