background: tumors involving the hand skeleton are rare. however, a basic knowledge of hand tumors is necessary for every clinician. this is due to the importance of distinguishing typical benign tumors from life or limb threatening malignant ones. methods: this study is a review of 99 cases of osseous hand tumors presented to the department of orthopedic surgery, imam khomeini hospital in tehr...

background: understanding the differences in genetics of malignancies is crucial for therapeutic decisions. this systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. material and methods: we performed a systematic review of the literature published on genetics of pediatrics bone tumors, using pubmed, google scholar, scie...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

background: despite the relative success of surgical resection followed by proton, proton/photon, or conventional radiotherapy in terms of recurrence-free survival, chordomas are still associated with a high rate of recurrence. to our knowledge there are only very few reported cases of this rare tumor detected by f-18 fdg-pet. materials and methods: in this case we show the significance of f-18...

the majority of osseous tumors of the hand are benign. the surgeon who evaluates and treats osseous tumors of the hand has to be familiar with limb anatomy, tumor biology, various presentations of the tumors and the range of treatment possibilities and their limitations. lesions in the hand more often present earlier in their course than those at other sites, just because they are more likely t...

the aim of this study was to assess the value of 99mtc-hexakis-2-methoxyisobutylisonitrile (mibi) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. methods: the scintigraphic findings for 84 patients were compared with the surgical and histologic findings. each patient underwent three-phase bone scan with 99mtc-methylene diphosphonat...

abstract background: osteoid osteoma is a benign bony neoplasm and its classic treatment is surgery. in the r ecent decades percutaneous laser therapy was suggested to be replaced by surgery. in this study we have reviewed the results of the first applications of interstitial laser photocoagulation (ilp) for treatment of osteoid osteoma in iranian patients. materials and methods: in this case s...

testicular cancer typically spreads to the lymph nodes, but hematogenous dissemination to distant organs can also occur. bone metastasis is uncommon and is thought to be a poor prognostic indicator. jaw metastasis is exceedingly rare but is of great clinical significance, since it may be the first sign of an occult testicular cancer or the first evidence of relapse of a known tumor. herein, we ...
