RESUMO
We report the clinical features of two cases presenting metastatic neck tumors (in the anterior neck and submandibular regions) secondary to myxoid liposarcoma of the lower extremity. Both cases underwent repeated resection of primary legions of the lower extremities because of recurrences. Such repeated surgical procedures are thought to be a risk factor for distant metastasis resulting from hematogeneous dissemination of tumor cells, although there is considerable debate about multicentricity versus metastasis in liposarcomas. Where possible, therapy for liposarcomas should initially comprise complete and wide resection of the lesions. Combined therapy consisting of surgery and postoperative radiation and chemotherapy should be investigated in the future.

A case of an 11-year-old female with cementifying fibroma in the ethmoidal sinus extending to the anterior cranial base was presented. She complained of slowly progressive nasal obstruction and anosmia. Magnetic resonance imaging (MRI) revealed a tumor in both ethmoidal and sphenoidal sinuses and nasal cavity. Although a tumor reduction surgery was attempted through a transnasal approach, tumor size increased gradually and right exophthalmos subsequently appeared. The pathological diagnosis was cementifying fibroma of the nose. Total tumor removal was consequently accomplished through the intracranial anterior transbasal approach. The surgical approach should be selected according to the site and expansion of the lesion in individual patients.

A 12-year-old, boy fell in the bush and suffered a penetrating neck wound. Computed tomography(CT-scan) was performed, but no foreign body was detected inside the wound. The patient returned home after ordinary wound care. About 6 months after the accident, the patient visited hospital, because of inflammatory neck pain. A CT-scan was performed and the foreign body appeared as a high density. Magnetic resonance imaging (MRI) revealed the presence of a large foreign body. Under general anesthesia the wooden (bamboo) foreign body was removed. This case highlights the needs to be aware of the potential for misinterpretation of CT images, especially in acute wooden penetration injury. Its also demonstrates that MRI is a useful adjust to CT in the detection of non-metallic foreign bodies.
