Osteoma is a benign tumour consisting of mature bone tissue. It is an uncommon lesion that occurs mainly in the bones of the craniofacial complex. Only a few cases involving the condylar process have been reported. An osteoma of the left condyle causing limited mouth-opening in a 32-year-old Malaysian Chinese female is reported here to alert the practitioner to consider this lesion as a diagnos...

Craniofacial osteomas may be located either superficially or intraosseously on any bone of the cranium or face or within a paranasal sinus. Osteomas within the paranasal sinus account for 0.01% to 0.43% of patients; of these, up to 80% occur in the frontal sinus. An osteoma of maxillary sinus is extremely rare. We describe a rare case of osteoma of a 56-year-old Asian woman in the maxillary sinus.

Osteoid osteoma is a benign bone tumor that rarely affects the carpal bones. Because of its nonspecific presentation in the wrist, it remains a diagnostic challenge. We report an unusual case of osteoid osteoma in the capitate where the diagnosis was delayed and the presentation was that of an aggressive natured lesion with considerable functional incapacitation. Diagnosis was made by computed ...

Osteoma is the most common benign tumor of the nose and paranasal sinuses. Most commonly seen in the frontal sinus, it is less common in the ethmoid and maxillary sinuses. This tumor may be discovered incidentally on radiographs, or may grow enough to produce symptoms. Rarely, complications occur at its location near the orbit and anterior skull base. We present a case of frontoethmoid osteoma ...

Extraskeletal chondrosarcoma is rare, making up only 1% of reported chondrosarcoma. We experienced 3 cases of extraskeletal chondrosarcoma, especially in vulva. They were suspected as lipoma of the vulva. The patients had noticed a small but growing mass on their vulva which had been palpated earlier. The masses were excised with a 2 cm resection margin. The final pathological reports confirmed...

Osteochondromas are common and typically arise from the metaphyseal ends of long bones. An osteochondral neoplasm of the soft tissue, which is a lesion of uncertain pathogenesis, is uncommon and usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extraskeletal osteochondromas also arise outside of synovial compartments. Most of the reported cases were presented in the ...

BACKGROUND This report describes the results of clinical, ultrasonographic and computed tomographic examination of a 16-year-old goat with extraskeletal osteosarcoma of the thorax. CASE PRESENTATION The lead clinical signs were abnormal condition and demeanour, fever, tachycardia, tachypnoea, dyspnoea and dilated jugular veins. Ultrasonographic examination of the thorax revealed a precardial ...

Extraskeletal Ewing's sarcoma is a rare soft tissue tumor that is morphologically indistinguishable from Ewing's sarcoma of bone. We report a case of extraskeletal Ewing's sarcoma with several systemic problems. A 69-year-old man presented with a 5-month history of a rapidly enlarging mass in the right thigh. Because preoperative radiotherapy with sanazole (AK-2123) contributed the tumor mass r...

Becker's nevus is a relatively common acquired focal epidermal melanotic hypermelanosis usually found in the region of the shoulder girdle of young men. Various skeletal malformations and cutaneous dermatoses have been reported in Becker's nevus. Osteoma cutis is a rare disorder characterized by compact bone formation in the dermis or subcutaneous tissue. Secondary ossification on nevi has been...

Radiofrequency ablation (RFA) therapy is recognised as a safe and effective treatment option for osteoid osteoma. This case report describes a 27-year-old man who underwent computed tomography (CT)-guided percutaneous RFA for a femoral osteoid osteoma, which was diagnosed based on his clinical presentation and CT findings. The patient developed worsening symptoms complicated by osteomyelitis af...
