1/130. Primitive sinonasal malignant mucosal melanoma: description of a case treated with radiotherapy (0-7-21 regimen).Mucosal malignant melanoma (MMM) of the nasal cavity and paranasal sinuses is rare and has a poor prognosis. The rarity of MMM of the ethmoid is also noteworthy and primary treatment has been, till now, surgery and/or radiotherapy (RT). Here we report a case of MMM arising in the ethmoid of a caucasian man and treated with hypofractionated RT. A 32 year-old man presented with symptoms of cephalalgia, obstruction and nasal bleeding; a computed tomography (CT) showed a large mass that involved ethmoid, left orbit and roof of the nasal cavity. After biopsy, a MMM was found. Chest radiography demonstrated the presence of multiple lung metastases and still the patient was submitted to palliative radiotherapy according to 0-7-21 regimen with a total dose of 24Gy/3 fraction/21dd, dose per fraction 8Gy. The patient was asymptomatic one month after the end of RT and three months later a CT demonstrated a partial remission. The patient died 17 months after the initiation of RT for disseminated disease, without clinical signs of tumoral regrowth in the irradiated site. This case confirms the efficacy and the safety of 0-7-21 RT regimen; the absence of symptoms after 17 months and the poor prognosis encourage the use of RT as primary treatment for MMM of the head and neck.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/130. October 1998--61 year old male with brain tumor and oral, lung, and palpebral masses.In Jan. 97 a gliosarcoma was diagnosed in a 61-year- old man after a 6-month history with neurological deficits. A total physical examination, laboratory tests, chest x-ray and abdominal ultrasound scanning revealed no gross abnormalities. Surgery was followed by brain radiation therapy and 6 months later there were metastases to the oral cavity, right palpebra and both lungs. The histological findings of the oral and palpebral metastases revealed only the sarcomatous component. We are aware of 15 cases of gliosarcoma with extraneural metastases, and in 4 of these, the metastases contained only the sarcomatous component. We believe that our case represents the fifth case of pure sarcomatous metastases.- - - - - - - - - - ranking = 1.2032273572878keywords = oral cavity, cavity (Clic here for more details about this article) |
3/130. Pulmonary metastasis of ameloblastoma: case report and review of the literature.Ameloblastomas are benign tumors of odontogenic epithelial origin. There is a high incidence of local recurrence associated with these tumors, and distant metastasis is rare. A review of the English literature shows that there have been 41 prior reports of pulmonary metastases from ameloblastomas of the oral cavity. We present another case of ameloblastoma metastatic to the lung and review the histopathology and mechanism of metastatic spread.- - - - - - - - - - ranking = 1.2032273572878keywords = oral cavity, cavity (Clic here for more details about this article) |
4/130. Cavitary lung cancer with an aspergilloma-like shadow.A 66-year-old man who complained of cough and haemoptysis had a cavitary lesion with the meniscus sign in the right lower lung field on his chest X-ray and CT scan. He had smoked 40 cigarettes daily, for about 46 years. Initially, he was diagnosed with aspergilloma and given an antifungal agent. After 2 months, the cavitary lesion showed a slight irregularity of the inner border. The walls were irregularly thickened and were surrounded by infiltrative densities compared with the previous chest radiograph. Enlargement of right hilar and mediastinal lymph nodes was also observed. The fungus ball-like shadow was fixed on the anterior wall of the cavity and its position was not altered with the patient's movements. These radiographic findings led to suspicion that the lesion might be malignant. Transbronchial lung biopsy of the cavity wall and CT guided needle aspiration biopsy of the fungus ball-like lesion were performed. Microscopic examination revealed a squamous-cell carcinoma in both the cavity wall and the fungus ball-like lesion. There was no evidence of fungal elements. In conclusion, the meniscus sign is most often associated with benign diseases such as aspergilloma, however, one should remember that carcinoma may be a cause.- - - - - - - - - - ranking = 1.5keywords = cavity (Clic here for more details about this article) |
5/130. Unusual late extrapulmonary metastasis in osteosarcoma.The major site of metastasis from osteosarcoma is the lung, and over 90% of fatalities in patients with this disease die from pulmonary metastases. Extrapulmonary disease is developing in an increasing proportion of patients, usually after pulmonary metastasis. This study reports three cases of patients with osteosarcoma that metastasized to the brain, mediastinum, intramuscular site, and pelvic cavity. The physician must be aware that extrapulmonary metastases may be present at the time a pulmonary metastasis becomes evident.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
6/130. A lung metastasis from giant cell tumor of bone at eight years after primary resection.We report a case of extensive pulmonary metastasis from a histologically benign giant cell tumor. A 34-year-old woman had undergone tumor resection, curettage and artificial bone grafting for giant cell tumor in the left tibia. At eight years after surgery, a chest radiograph revealed an extensive tumor shadow in the right thoracic cavity. Tumor resection with right upper and middle bilobectomy was performed. Its histological features were consistent with those of the primary tumor of the tibia. Distant metastases from a giant cell tumor of bone are rare, with only 50 reported cases. Metastasis has occurred mainly within 3 years after the primary resection. However, in 20% of reported cases, metastasis occurred after 5 years or longer. Long-term follow-up and careful observation for distant metastasis are necessary for this histologically benign disease.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
7/130. Surgical management of primary lung cancer in an elderly patient with preoperative empyema.A 74-year-old man with primary lung cancer developed preoperative empyema but was successfully managed surgically. The patient was given a diagnosis of c-T2N1M0, stage IIB, moderately differentiated squamous cell carcinoma, but before surgery pneumothorax and empyema developed, resulting from rupture of the carcinoma. Thoracic drainage, lavage and systemic administration of antibiotics improved his empyema. As there were no malignant cells in the drainage fluid, right middle-lower bilobectomy, empyemal cavity resection and lymph node dissection were performed. The bronchial stump was covered with an intercostal muscle flap. Thoracic drainage, lavage and systemic administration of antibiotics were performed for 6 days following the operation. The patient was discharged on the 27th postoperative day without any complications having developed. The pathological diagnosis of the tumor was p-T4N2(#7)M0, stage IIIB, br(-), ly( ), v( ), p3(pleura), pm1 and d0. He died of recurrence at home 18 months after the operation. We believe the following to be the minimum requirements for surgical management of such patients: (1) immediate thoracic cavity drainage and lavage with systemic antibiotic therapy, aiming at infection control before surgery; (2) prophylactic lavage of the thoracic cavity during and after surgery and (3) coverage of the bronchial stump with an adequate flap. Six reported cases of primary lung cancer with preoperative empyema are also discussed.- - - - - - - - - - ranking = 1.5keywords = cavity (Clic here for more details about this article) |
8/130. Solitary squamous cell papilloma of the lung in a 40-year-old woman with recurrent laryngeal papillomatosis.A rare case of recurrent respiratory papillomatosis (RRP) is reported with a review of the literature. A 40-year-old Japanese woman had suffered from RRP since 1 year of age. She developed a pulmonary squamous papilloma with a thin-walled cavity, which was suspected as being lung carcinoma. The trachea and bronchi around the tumor were intact, and no malignant transformation was present. Two types of human papillomavirus, 6 and 16, were detected, both in the laryngeal and pulmonary papillomas by in situ hybridization and the polymerase chain reaction method. To date, only 40 cases of juvenile laryngeal papilloma with pulmonary involvement have been reported in the English literature.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
9/130. A case of endobronchial aspergilloma.pulmonary aspergillosis may be classified under three categories, depending upon whether the host is atopic or immunocompromised: invasive aspergillosis, allergic bronchopulmonary aspergillosis (ABPA) or aspergilloma. However, it is not always possible to effectively categorize this disease. We experienced a case of endobronchial aspergilloma, which was difficult to categorize, in a healthy male patient. The chest X-ray and computed tomography showed an ill-defined nodule mimicking lung cancer. Fiberoptic bronchoscopy revealed an aspergilloma without cavity formation in the left lower laterobasal segmental bronchial orifice. The aspergilloma was removed and the patient's symptoms were relieved. We present this unusual case with a review of the literature.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
10/130. Resected early lung cancer with pulmonary aspergilloma.pulmonary aspergillosis and lung cancer rarely occur simultaneously. We report a 66-year-old man with a round shadow in the thin-wall cavity of the right upper lobe. Radiological findings and transbronchial biopsy revealed squamous cell carcinoma complicated by aspergilloma at the site. Right upper lobectomy suggested that early lung cancer arose from preexisting lung scars containing an aspergilloma.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
