Introduction: Epidemiologic data of upper extremity tumors are still few and sometimes conflicting. In our department, hand surgeons manage these tumors. Good documentation of patients’ information permitted us to make an epidemiologic study on the tumors of the upper extremity operated in our department. Methods: We retrospectively studied all the cases of upper extremity tumors operated from...

BACKGROUND Primary hyperparathyroidism is an endocrinopathic condition characterized by hypersecretion of parathyroid hormone. Excess parathyroid hormone results in an altered state of osseous metabolism involving bone resorption and tissue change known as osteitis fibrosa cystica, which is the end stage of primary hyperparathyroidism. Osteitis fibrosa cystica is associated with the development...

Squamous Cell Carcinoma of the temporal bone is an uncommon entity accounting for fewer than 0.2% of all tumors of the head and neck and is associated with a poor outcome. Temporal bone carcinoma includes cancers arising from pinna that spreads to the temporal bone , primary tumors of the external auditory canal (EAC), middle ear, mastoid, petrous apex and metastatic lesions to the temporal bon...

retrorectal tumors are rare lesions in adults, which remains a difficult diagnostic and management problem. the purpose of this study was to evaluate the results of surgical management of retrorectal tumors in our institution. in a retrospective study, a consecutive series of patients who underwent surgical excision of a retrorectal tumor were identified from a database. medical records, radiol...

We report case 19-year-old man with low grade chondrosarcoma secondary to transformation osteochondroma right distal femur. Here we discuss osteochondroma, chances malignancy chondrosarcoma, work up done in our case, histopathological features differentiate from ...

statement of the problem early detection of periodontal disease and distruction is important for prevention of further destruction of the tissues. we carried out this study to determine the normal cement enamel junction (cej) to alveolar bone crest (abc) distance in the interproximal area of primary molars on bitewing (b. w) radiographs in healthy 7-9 year old girls living in hamadan, iran. mat...

Dermoid cysts are common orbital developmental tumors in childhood. They account for 3 to 9% of primary tumors. considered be congenital, but not all them diagnosed at birth. benign choristomas that arise from sequestration ectoderm along the lines embryonic fusion mesodermal processes destined bone. In most cases, lesion is close zygomatic-frontal suture leading a superotemporal subcutaneous m...

We present a case of spinal tumor, with fibrohistiocytoma combined with aneurysmal bone cyst (ABC) at the pedicle and transverse process of T7 in a 63-year-old female. ABC is a rare skeletal tumor and spinal ABC is extremely rare. Fibrohistiocytoma is a type of primary benign bone tumor. ABC is also a rare bone tumor that most often occurs in the pelvis. The combined lesion of two primary bone ...

Primary adenoid carcinoma are rare skin tumors. We present a 75-year-old female with this primary cutaneous tumor of the scalp with additional bone involvement. Wide scalp excision with bone enclosure, latissimus-dorsi-free-flap defect overage, and subsequent radiation slowed down the disease but could not prevent further skull infiltration.

Primary extradural meningiomas presenting as scalp swelling is uncommon. Their diagnosis by fine needle aspiration is rare as majority of the lesions are hyperostotic. Primary intraosseus meningiomas involving the skull constitute only about 2% of meningiomas and are often mistaken for other primary or secondary bone tumors. The authors report a case of primary calvarial meningioma involving th...
