Primary intradural extraskeletal Ewing sarcoma is a very rare form of malignant neoplasm. Only few cases have been reported on the literature. Here, we report a case of a 14-year-old boy who had a chief complaint of pain and tingling in the right lower limb. The patient initially seemed to have a giant nerve sheath tumor but was eventually diagnosed with intradural extraskeletal Ewing sarcoma a...

Osteomas are benign slow growing osteogenic tumors mostly arising in the craniofacial region and characterized by deposition of differentiated mature either or both cancellous compact bone. Osteoma accounts for 2-3% all bone primary with an incidence 10-12% among skeletal neoplasms. Objective: The objective this work is to describe a clinical case osteoma temporomandibular joint diagnosed maxil...

Extraskeletal osteochondroma in the nape of the neck is rare and its pathological diagnosis is based on radiological and histopathological examination. It is vital that such a diagnosis be considered when a discrete, ossified mass is localised in soft tissues, even at atypical sites. Differential diagnoses include myositis ossificans, a lipomatous lesion, a pseudomalignant osseous tumour, an os...

Extraskeletal osteosarcoma is a rare malignant soft tissue tumor. Here we present a case of a primary extraskeletal osteosarcoma arising from omentum majus in a 40-year-old Chinese woman. Ultrasonography of the pelvic cavity showed a large soft tissue mass with marked calcification. Complete surgical resection of the primary tumor was performed and the histopathological diagnosis was extraskele...

Osteomas of the middle ear are rare lesions. We report the case of a 20-year-old male with osteoma originating from the promontory coincident with tympanic membrane perforation. Histopathological diagnosis was performed by means of a superficial curettage during surgery, to avoid a cochlear fenestration. Postoperative closure of the airbone gap after myringoplasty confirmed the presumed asympto...

BACKGROUND: Osteoma is a benign bone tumor with an incidence rate of about 1% primary tumors. the nasal rare case and recurrence reported in literature after surgery 10%. most often occurs young people second third decades, mostly men. can be treated surgically external approach or endoscopic approach. The surgical technique incision open rhinoplasty transcolumella extensions effective, because...

Osteoid osteoma is a benign bone tumour that usually develops in the long bones of body such as femur & tibia. It causes continuous, deep and severe pain at night, Swelling, joint stiffness. Modalities management modern medicine are limited many patients suffer from post RFA complication like pain, general debility, gait disorder etc. Hence, there need more efficient methods to treat this. ...

BACKGROUND Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. CASE REPORT Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery...

Osteoma cutis is a bone formation in the dermis can to be primary or secondary forms. Only, multiples, many forms, occurring on either sex, they are a rare cutaneous disease. The pathogenesis and classification remains unclear. Our objective was the diagnostic and small invasive surgery treatment of the osteoma cutis multiple of the face, in patients as a sequel of acne. To remove the osteoma w...

Osteomas, the most common skull tumors, are typically excised through either an open or endoscopic ostectomy using a high-speed drill, a technically challenging procedure that can result in injury to adjacent soft tissue structures. Osteoma removal through ultrasonic bone emulsification and aspiration (UBA) offers the advantages of decreased blood loss, preservation of adjacent soft tissue stru...
