1/214. Metastatic esophageal carcinoma to the orbit.PURPOSE: To report a case of esophageal adenocarcinoma and areas of gastric differentiation in the esophagus (barrett esophagus) metastatic to the orbit. methods: A 47-year-old man with a history of esophageal carcinoma developed turgescence around his left eye. He underwent a biopsy and histologic examination of a left orbital mass. RESULTS: Histopathology of the orbital tumor was consistent with metastatic adenocarcinoma from the esophagus. CONCLUSIONS: This metastatic adenocarcinoma to the orbit likely arose in barrett esophagus.- - - - - - - - - - ranking = 1keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
2/214. Microvascular reconstruction of the skull base: indications and procedures.PURPOSE: The aim of the current study was to review the use of free tissue transfer for reconstruction of the skull base and for coverage of intracranial contents. patients AND methods: From 1990 until 1996, revascularized flaps were transferred to the skull and the skull base in 11 patients in whom intracranial/extracranial resection of tumors of the skull base was performed in cooperation with the Department of neurosurgery. The defects resulted from removal of squamous cell carcinomas (n = 4), basal cell carcinomas (n = 4), malignant melanoma, malignant schwannoma, and malignant meningioma. Defect repair was accomplished by revascularized transfer of latissimus dorsi muscle flaps in seven cases and rectus abdominis flaps and forearm flaps in two cases each. In five patients with extensive intracranial tumor spread, reconstruction was performed for palliative reasons. RESULTS: A safe soft tissue closure of the intracranial and intradural space was achieved in all patients, whereas the contour of the facial skull and the neurocranium was satisfactorily restored at the same time. By using the entire length of the grafted muscle, the vascular pedicle could be positioned next to the external carotid artery and conveniently connected to the cervical vessels. The mean survival time of the patients with palliative treatment was 8.4 months, with an average duration of hospital stay of 24.5 days. CONCLUSIONS: Despite the increased surgical effort of revascularized tissue transfer, microvascular reconstruction of large skull base defects appears to be justified, even as a palliative measure.- - - - - - - - - - ranking = 0.24475661134572keywords = carcinoma (Clic here for more details about this article) |
3/214. Fatal cutaneous squamous cell carcinoma with extension through the maxillary sinus and orbit into the brain.Cutaneous squamous cell carcinomas may cause death by metastasis or by local extension. We describe a deeply invasive cutaneous squamous cell carcinoma that caused death by direct extension into the brain.- - - - - - - - - - ranking = 0.73426983403716keywords = carcinoma (Clic here for more details about this article) |
4/214. Extensive destruction of the eyeball by invasion of basal cell carcinoma of the eyelid.BACKGROUND: Eyeball destruction caused by invasion of basal cell carcinoma of the eyelid. CASE: A 100-year-old woman showed extensive eyeball destruction caused by the invasion of basal cell carcinoma of the eyelid. Complete ophthalmologic examinations, including computed tomographic (CT) scans of the orbit, were performed. The patient underwent incisional biopsy and bacteriological examination of the exudate from the lesion. OBSERVATIONS: Orbital CT scan showed a mass in the extraconal space of the right orbit, with extension to the adjacent sinus cavity without brain involvement. The remnant of the eyeball was posteriorly displaced. pseudomonas aeruginosa was identified by culture examination of the exudate. Histological study of the biopsy specimen showed basal cell carcinoma of the noduloulcerative type. CONCLUSIONS: Basal cell carcinoma of the eyelid had caused severe periorbital and eyeball destruction.- - - - - - - - - - ranking = 0.97902644538288keywords = carcinoma (Clic here for more details about this article) |
5/214. Orbital metastasis due to interval lobular carcinoma of the breast: a potential mimic of lymphoma.A 53-year-old woman had an orbital mass composed of a neoplastic small round cell infiltrate and no apparent extraorbital primary tumor. Although the initial diagnosis was primary orbital lymphoma, a combination of mucin histochemistry and immunohistochemical staining for cytokeratin and estrogen receptors led to the discovery of an impalpable lobular carcinoma of the breast. We discuss how detailed histopathological assessment can lead to beneficial therapy.- - - - - - - - - - ranking = 0.6118915283643keywords = carcinoma (Clic here for more details about this article) |
6/214. Gamma probe localization of cranial bone lesions.PURPOSE: Staging of cancer is essential to formulate appropriate treatment plans and to help predict prognosis. A solitary region of increased radionuclide uptake ("hot spot") on a bone scan may represent a metastasis or a masquerading lesion. biopsy may be required to determine its histologic nature, but localization of the site may be difficult because bone scans provide poor spatial resolution. methods: In two patients with breast carcinoma, radioactive technetium was administered intravenously and a gamma probe was used preoperatively and intraoperatively to identify the site of cranial bone involvement. RESULTS: The lesions were resected; one was a benign fibro-osseous lesion and one was a metastatic breast adenocarcinoma. CONCLUSIONS: A gamma probe may be helpful in localizing the site of radioactive uptake identified by bone scan.- - - - - - - - - - ranking = 0.25174779621809keywords = carcinoma, adenocarcinoma (Clic here for more details about this article) |
7/214. Hepatocellular carcinoma metastasizing to the orbit diagnosed by fine needle aspiration cytology.Hepatocellular carcinoma (HCC) rarely metastasizes to the orbit. We report a case of a 78-year-old man with a past history of HCC, who presented with a periorbital mass, which was diagnosed as metastatic HCC by fine needle aspiration cytology (FNAC) and subsequently confirmed on excision biopsy. The cytological, histopathological and immunohistochemical findings are presented and the differential diagnosis is discussed. To our knowledge there has been no previously reported case of HCC metastatic to the orbit diagnosed by FNAC.- - - - - - - - - - ranking = 0.6118915283643keywords = carcinoma (Clic here for more details about this article) |
8/214. Superior vena cava obstruction caused by radiation induced venous fibrosis.superior vena cava syndrome is most often caused by lung carcinoma. Two cases are described in whom venous obstruction in the superior mediastinum was caused by local vascular fibrosis due to radiotherapy five and seven years earlier. The development of radiation injury to greater vessels is discussed, together with the possibilities for treatment of superior vena cava syndrome.- - - - - - - - - - ranking = 0.12237830567286keywords = carcinoma (Clic here for more details about this article) |
9/214. Orbital metastasis as primary manifestation of thyroid carcinoma.A 59-year-old woman with unknown primary tumor developed progressive painless left upper eyelid swelling and exophthalmos. Computed tomography (CT) showed a well-circumscribed left orbital mass producing bone lysis. Immunohistologic staining of the incisional biopsy specimen was positive for thyroglobulin, suggesting an orbital metastasis from thyroid carcinoma. At this time, thyroglobulin was high (1400 ng/dL). Total thyroidectomy with lymph node dissection disclosed a follicular carcinoma with microscopic foci of papillary variant follicular carcinoma. Two months after radioiodine treatment, the CT showed a regression of the orbital tumor mass with concomitant decrease in thyroglobulin (428 ng/dL). Although orbital metastases of thyroid carcinoma are uncommon, thyroid carcinoma has to be considered as a potential primary tumor in a patient with an orbital metastasis.- - - - - - - - - - ranking = 1.1014047510557keywords = carcinoma (Clic here for more details about this article) |
10/214. Mucoepidermoid carcinoma of an accessory lacrimal gland with orbital invasion.PURPOSE: To report a case of mucoepidermoid carcinoma of an accessory lacrimal gland with orbital invasion. methods: The clinical history and pathologic findings of a patient with a left upper eyelid lesion were reviewed. RESULTS: The patient was evaluated and found to have an epithelial tumor arising in an accessory lacrimal gland. Special stains showed mucin production by individual tumor cells. The tumor was classified as mucoepidermoid carcinoma. CONCLUSIONS: Mucoepidermoid carcinoma may arise in accessory lacrimal glands and invade the orbit.- - - - - - - - - - ranking = 0.85664813971002keywords = carcinoma (Clic here for more details about this article) |
