Although thyrotoxicosis and orbital complications of acute ethmoid or frontal sinusitis are among the most common causes of unilateral exophthalmos, inflammatory pseudotumor is frequently accompanied by progressive acute unilateral proptosis. Because the associated chemosis, scleral erythema, and ophthalmoplegia constitute a spectrum of clinical findings present in numerous inflammatory orbital disorders and systemic diseases, the diagnosis of inflammatory pseudotumor is one of exclusion, often requiring orbital biopsy. Four patients without evidence of sinusitis, endocrinopathy, collagen vascular disease, or Wegener's granulomatosis are described. The diagnosis of orbital pseudotumor was disclosed by computed axial tomography, thus avoiding orbitotomy. The finding of scleral and choroidal thickening with enhancement following intravenous contrast injection represents a select group of patients with orbital pseudotumor and differentiates them from patients with endocrine exophthalmopathy or neoplasms. This noninvasive technique is extremely valuable because early diagnosis is critical for successful treatment. All four patients responded dramatically to high-dose corticosteroid therapy. In the absence of significant clinical response, however, Wegener's granulomatosis, lymphoma, and rhabdomyosarcoma, especially in younger patients, must be carefully excluded. Orbital exploration or decompression or both are used when proptosis, headache, or orbital pain does not resolve promptly, visual acuity deteriorates, or the diagnosis remains unknown.

Hyperthermia greater than or equal to 42 degrees C is tumoricidal in vitro and in many animal models, although such temperatures have only recently been achieved experimentally in some human cancers. A recently developed radio frequency device that provides safe hyperthermia to any depth without surface tissue injury now permits evaluation of the effects of hyperthermia on advanced human sarcomas. Twelve patients with large sarcomas located intraabdominally [7], in the chest wall [2], proximal extremity [2], and the neck [1], were evaluated in this study. Tumor types include liposarcoma [3], rhabdomyosarcoma [2], leiomyosarcoma [2], neurofibrosarcoma [2], and one each malignant mesothelioma, undifferentiated sarcoma, and osteosarcoma. Intratumor temperatures greater than or equal to 42 degrees C were observed in all tumors, with virtually no normal tissue injury. Selective tumor heating greater than or equal to 45 degrees C occurred in 9/12 (75%) and greater than or equal to 50 degrees C in 6/12 (50%). One to five weekly treatments greater than or equal to 50 degrees C and ten daily treatments greater than or equal to 45 degrees C resulted in significant tumor necrosis and pain relief in some patients. Hyperthermia of advanced sarcomas is possible with little host toxicity and may be of potential therapeutic benefit.

For the 1967-1989 period of time of 225 patients with malignant nonorganic small pelvis tumors in 15 the soft tissues rhabdomyosarcoma of small pelvis cavity was diagnosed (including 7 children and 8 adults). The main tumor symptoms are the pain and the disorders of physiologic excretions. The fourth stage of the disease was diagnosed in 13 of 15 patients. In spite of performance of extensive combined intervention, chemotherapy and irradiation therapy the treatment results are poor: the whole of the patients have died for a period of 3 years (mainly up to 1 year period of time).

Chest wall tumors are infrequent in infants and children, but a high proportion of these tumors are malignant. They present most frequently as a palpable mass, and less frequently with pain or respiratory distress. Radiographic evaluation should include chest radiographs followed by computed tomographic (CT) scan. In most cases an initial incisional biopsy is performed because of the significant risk of malignancy. The most frequent tumors are the malignant small round cell tumors (Ewing's sarcoma/primitive neuroectodermal tumor [PNET] family) followed by rhabdomyosarcoma, osteosarcoma, chondrosarcoma, and a spectrum of other sarcomas. Initial treatment with chemotherapy, particularly for the malignant small round cell tumors and osteosarcoma, may facilitate resection by decreasing the size of the tumor as well as its vascularity and friability. Cure requires successful local control and adjuvant chemotherapy and is particularly difficult to achieve in children presenting with metastases.

Thirty-five patients (10 men and 25 women) with a preoperative diagnosis of cardiac myxoma have undergone cardiac surgery since 1964 at the University of Louvain. The mean age of the patients was 49 (range 20-75) years. The most commonly encountered symptoms were: dyspnoea 49%; thoracic pain 26%; cough and peripheral embolism 17% each; stroke and preoperative atrial fibrillation 14% each; flutter 11%; expectoration, acute pulmonary oedema, syncope and transient ischaemic attack 6% each; and pulmonary embolism 3%. The different locations were: left atrium 66%; right atrium 26%; both atria 3%; right ventricle 3%: and retrohepatic vena cavae 3%. Septal implantation was found in 66%. Histological examination confirmed 28 myxomas but three 'tumours' were thrombi, two haemangiomas, one rhabdomyosarcoma and one liposarcoma. The follow-up has now reached 2829 months with an average of 81 months per patient (range 0-342 months). Three patients died early (9%) and there were four late deaths (11%). No cases were familial. Surgical resection is the correct treatment for cardiac myxomas and gives good long-term results.

Surface epithelial tumours (SET) constituted 65.7% of all the ovarian tumours. Benign tumours were 182 (71.9%), of low malignant potential (LMP) 11 (4.4%) and frank malignant 60 (23.7%). Maximum number of cases, 102 (40.3%) belonged to 3rd decade. Mean age for serous cystoma was 31.5% years as compared to 30.8 years for mucinous cystoma. The commonest presenting feature was the abdominal lump observed in 182 cases (71.9%) and pain in abdomen in 120 (47.4%). Serous cystomas were t he most frequent tumours and comprised of 32.21% of all the ovarian tumours or 46.01% of all the SET or 65.56% of all the cystic SET. Seventeen (11.7%) of serous tumours were bilateral. Mucinous cystomas constituted 14.55% of all the ovarian tumours or 30.8% of all the SET. These tumours were bulky (78.6%; 15 cm diameter) and multilocular (83.9%). Mucinous cystadenocarcinoma was the commonest malignant epithelial tum our (36.6%). Endometroid carcinoma comprised 3.65% of all the SET or 8.4% of all the ovarian malignancy. Squamous metaplasia was seen in one case whereas 2 cases were of mesodermal mixed tumour with heterologous element as rhabdomyosarcoma. Clear cell carcinoma, Brenner tumour and unclassified group constituted 0.79%, 1.18% and 1.58% of all SET respectively.

Nine children (6 boys, 3 girls) were diagnosed with a primary endobronchial or pulmonary parenchymal neoplasm. The average age at diagnosis was 9 years. Presenting complaints included cough (7), fever (5), pulmonary infection (3), respiratory distress (3), weight loss (2), pain (2), and hemoptysis (1). Pulmonary x-rays showed persistent atelectasis, pneumonic infiltrates or mass lesions. A computed tomography scan was performed in 8. Five of six endobronchial tumors were diagnosed with bronchoscopy and biopsy. Treatment consisted of thoracotomy and pulmonary resection in 7 cases and laser resection in 2. The pathologic diagnoses were bronchial carcinoid (3), bronchial mucoepidermoid carcinoma (1), inflammatory pseudotumor (plasma cell granuloma) of the bronchus (2) and of the lung parenchyma (1), fibrosarcoma (1), and rhabdomyosarcoma (1). Postoperative chemotherapy was given only to the patient with pulmonary rhabdomyosarcoma; this child died. One child has developed a local recurrence while 7 children are alive and free of disease at an average of 2.4 years postresection. Pulmonary neoplasms are unusual in the pediatric age group and represent a wide spectrum of pathology. Including the present series, 383 tumors have been described. Seventy-six percent were malignant. Early investigation and surgical intervention are essential in children with persistent pulmonary symptoms or x-ray abnormalities. In most cases, the prognosis is excellent with complete surgical resection; however, malignancies other than bronchial adenoma are associated with significantly mortality.

A case of rhabdomyosarcoma in a 14-year-female is reported herein. The patient developed left inguinal pain and tumor. She was initially seen by her local medical doctor, who biopsied her left inguinal tumor with a pathological report of malignancy. She was referred to the Ryukyu University Hospital in July, 1990. CT and MRI demonstrated a large tumor 10 cm in diameter arising from the left iliac region. The tumor was extirpated and the pathological report indicated rhabdomyosarcoma (alveolar type). The patient was treated with VAC chemotherapy and local irradiation. Her course has been uneventful for the past 2 years without any clinical manifestation of recurrence since surgery.

Cancer-related problems are seen frequently by the emergency physician. More difficult presentations are seen with premonitory symptoms, paraneoplastic syndromes, and nonspecific lesions. Dermatologic paraneoplastic syndromes are numerous, nonspecific, and consist of hamartomatous growths, texture changes, new hair growth, or changes in skin color. Alteration of skin color may be of practically any color, localized or diffuse, and of sudden or indolent onset. Hormone production by tumors may lead to acne, hirsutism, gynecomastia, or a cushingoid appearance. Pruritus may herald the onset of leukemia or lymphoma and be intolerable, as with erythroderma. All suspicious presentations require thorough investigation for underlying disease. Metastasis to skin is not common and implies a poor prognosis if seen. Most metastases are seen on the head and neck, anterior chest wall, and abdomen. Basal cell and squamous cell carcinomas commonly occur in sun-exposed areas. Basal cell is locally destructive, whereas squamous cell occasionally metastasizes to local lymph nodes. Malignant melanoma is the leading fatal illness originating in skin, with a dramatic rise in incidence. It is classically described as asymmetric with irregular borders, is elevated, and shows color variegation; however, melanoma may present atypically, particularly in non-whites. Kaposi's sarcoma lesions are well-demarcated, symmetric, smooth nodules that appear purplish-brown, particularly if below the knee (owing to venous stasis). The closely interrelated structures of the eye and orbit are easily disturbed, leading to the presenting symptoms of visual disturbances, exophthalmos, pain, and ocular motility disorders. Primary tumors are not unusual and may include retinoblastoma, rhabdomyosarcoma, and melanoma. Equally common are metastatic lesions, most commonly lung and breast carcinoma. An estimation of the malignancy of bony lesions can be made by assessing the zone of transition, periosteal reaction, and bone destruction. A malignant lesion will more likely have a broad zone of transition, irregular periosteal reaction, and moth-eaten or permeative destruction of trabeculae. Metastatic bone lesions primarily occur in sites of persistent red marrow: skull, ribs, vertebrae, pelvis, and proximal humerus and femur. Bony lesions can be blastic or lytic in nature. Solitary pulmonary nodules that have not grown for 2 years can be assumed to be benign. Calcification seen on plain films are a strong (but not absolute) indication of benignancy. Lesions that are greater than 3 to 4 cm in diameter, have irregular contours, are cavitated with thick walls, have multiple peripheral nodules, and have lack of calcification are more likely malignant.

Antineoplastic therapy causes developmental disturbances in the dental enamel and root if children are treated during tooth development. Increased caries activity has also been reported. The effect of anticancer therapy on the function of the masticatory system (i.e. jaws, dentition, masticatory muscles) is not well known. A case report of a 9-year-old girl with right auricular rhabdomyosarcoma is presented. She received irradiation of 50 Gy to the right auricular area and chemotherapy. A year and a half after cessation of cancer therapy, she was disease free and the clinical stomatognathic examination combined with electromyogram (EMG) registration of the masseter and temporal muscles and magnetic resonance imaging (MRI) examination of the temporomandibular joints (TMJ) revealed a strongly restricted mouth opening capacity, painful right TMJ, and flattened head of the right mandibular condyle. Muscle atrophy in the right masseter muscle was clearly visible but EMG activities of the masseter and temporal muscles, however, were higher on the right than on the left. More severe developmental defects, and worse gingival and cariological health were observed on the right side than on the left side. She developed 12 carious lesions and all the lesions were on the right maxilla or mandible or on anterior teeth. The left side was not affected. Intensive prophylactic dental care after cancer treatment is important in order to prevent caries and gingival inflammation. Stomatognathic treatment (i.e. management of occlusal and dysfunctional problems) may improve the mouth opening capacity and relieve pain.
