Twenty-two cases of intravenous leiomyomatosis (IVL) of the uterus were examined at the Royal Women's Hospital, Melbourne, within a 22-year period. The mean age of the patients was 46 years (range, 23-66). Nine patients presented with a pelvic mass, nine with abnormal uterine bleeding, and one with prolapse of the uterus. In three cases, the presenting features were unknown. Surgical exploration confirmed the presence of a uterine mass (mean size, 7.8 cm) which in seven cases extended into the broad ligament. In only 11 cases was involvement of the myometrial vessels obvious on gross examination. However, no extension into the iliac veins or inferior vena cava was found. In seven cases, the tumor involved to a minimal degree the immediately adjacent or contiguous myometrial veins, and the diagnosis of IVL was made incidentally on microscropic examination. Of the 16 patients with follow-up (mean, 7.5 years) all are now disease free. Five years after the diagnosis of IVL, one patient (case 10) had a pulmonary smooth-muscle tumor resected. All 22 patients were treated by surgery alone, and to date none have died from disease. Our findings support the benign biologic behavior of IVL even in the presence of metastases.

Between May 1986 and February 1990, 126 consecutive men underwent lower urinary tract reconstruction by means of bilateral ureteroileal urethrostomy using a Kock ileal reservoir. The early complication rate was 11.1%. Late complications requiring rehospitalization or reoperation have been surprisingly few: 1 for prolapse of the afferent antirefluxing nipple valve, 1 for calculi and 4 for artificial urinary sphincter placement due to unsatisfactory continence. Good continence has been achieved in 94% of the patients during the day and in 84% at night. Tumor recurred in the pelvis in 5 patients, with 4 requiring cutaneous urinary diversion. All patients had progression or died of metastatic disease. Our experience has yielded extraordinary results in terms of patients acceptance with few late complications or need for reoperation.

A combination of increased perioperative morbidity, together with the technical difficulty of an R 0 (curative) resection, is responsible for the poor prognostic factors of supradiaphragmatically extending renal tumors. Six patients aged 53-70 years with vena cava thrombosis extending into the right atrium or ventricle underwent en bloc resection of the primary tumor and tumor thrombus removal. If the atrial tumor mass was large or extended into the ventricle, resection was performed during cardiopulmonary arrest using a cardiopulmonary bypass method with the patient in deep hypothermia (< 18 degrees C). Alternatively if the cardiac tumor infiltration was minimal, resection was performed during an optionally short cardiopulmonary arrest period using a cardiopulmonary bypass method with the patient in hypothermia (23 degrees C). The operative procedure was determined by intracardiac tumor extension, tumor wall adhesions and tumor wall infiltrations, all of which were assessed intraoperatively by vena cava sonography. Six patients were strongly symptomatic preoperatively. Three developed sudden life-threatening cardiopulmonary insufficiency, possibly due to longer-lasting tricuspital valve prolapse with a consecutive right-to-left shunt through a newly reopened foramen ovale. One patient died 14 months postoperatively because of multiple metastases (hepatic, pulmonary and bone). One patient is still alive and has had a local recurrence for 2 months, which was diagnosed 65 months postoperatively. The remaining four patients are alive and well. They have been tumor-free for extended periods of time (29, 34, 62 and 84 months, respectively).

A seven-year-old entire male Irish setter was presented because of a neck mass, prolapse of the third eyelid and apparent drooping of the upper eyelid. Historical findings included increased appetite as well as polyuria and polydipsia for about two weeks. The most remarkable findings on physical examination were right-sided Horner's syndrome, pre-scapular lymphadenopathy and a large, ventral cervical mass. Lateral cervical radiographs showed a large, soft tissue opacity surrounding the trachea and retropharyngeal area which was causing displacement and narrowing of the cervical trachea and oesophagus. Results of thyroid testing suggested hyperthyroidism. At necropsy, a large, invasive tumour was identified in the ventral cervical region and multiple metastases of various sizes were detected in the lungs. Histopathological examination of the tumour revealed follicular thyroid carcinoma and confirmed widespread pulmonary metastasis.

Renal cell carcinoma (RCC) is the most common malignancy involving the kidney. Only rarely does it metastasize to the eye and orbit, sometimes mimicking other lesions. A 70-year-old woman was referred from neurology because of a right orbital lesion, six months after the start of a neurological investigation because of amaurosis fugax. Six months earlier she had complained of transient visual disturbances in her right eye. After excluding cardiovascular abnormalities and coagulopathies as the source of her complaints, she was diagnosed as having a right senile ptosis. A computed tomography scan, done to complete the workout, detected a right orbital mass. The patient was referred to the oculoplastic unit. A biopsy and then a lateral orbitotomy were performed. Histopathological examination proved it to be a metastatic renal cell carcinoma, seven years after the primary tumor had been diagnosed and treated by nephrectomy. The characteristics of metastatic renal cell carcinoma are discussed, in view of the rarity of metastasis to the eye and, in particular, to the orbit, and its tendency to masquerade as other lesions or symptoms. In this case it presented as amaurosis fugax before other signs appeared.

Clinical symptoms in patients with primary orbital lymphosarcoma, generalized lymphosarcoma involving the orbital tissues, and metastatic tumors of the orbit of another origin are analyzed. The orbital process has bee studied in 158 patients. The most frequent symptoms were ptosis and exophthalmos. Decreased visual acuity, pain, sensation of swelling in the orbit caused by rapid tumor growth were characteristic of metastases to the tumor and orbital lymphosarcoma in total system's involvement. In case of an isolated involvement of the orbit, lymphosarcoma ran a more swift course than metastases to the orbit and orbital lymphomas in systemic involvement which ran an aggressive course. These data cannot serve as differential diagnostic signs. The decisive information is provided by morphological examination of a biopsy specimen.

Postoperative infection remains a troublesome but not uncommon complication after spinal surgery. Most previous reports, however, are small or involve cases with more than one surgeon often at different institutions. This study represents a single surgeon's 9-year experience with postoperative infection at one institution. The authors describe the features of wound infection after spinal surgery with reference to diagnosis, microbiology, and treatment and they describe a protocol for effective management of postoperative spinal wound infection. The records of the senior author (F.P.C.) during a 9-year period for cases of postoperative wound infection were reviewed. Of 2,391 operative procedures, 46 cases of wound infection were identified, yielding an overall infection rate of 1.9%. Patients' preoperative risk factors, original diagnosis prompting the surgery, onset of infection, presentation, treatment, and outcome were analyzed. The mean age of the 23 men and 23 women was 57.2 years. The preoperative diagnoses included lumbar degenerative scoliosis or spinal stenosis in 28 cases, disk prolapse in 8 cases, metastatic disease in 4 cases, degenerative disk disease in 1 case, and a group of 5 miscellaneous cases. Seventeen (37%) of the patients underwent at least one previous spinal surgery at the same site. Twenty-three patients had a fusion, of whom 22 also had instrumentation. Forty-three (93%) of the patients had significant wound drainage after an average of 15 days (range, 5-80 days). The other three patients were examined approximately 2 years after the surgery. Fourteen of the patients also had pyrexia (temperature >37.5 degrees C) at presentation. Staphylococcus aureus alone was cultured in 29 patients, whereas another six patients had a different single organism. In nine patients, more than one organism was cultured during their hospital stay. Surgical treatment included primary closure in only seven patients, with most undergoing wound drainage and debridement followed by delayed closure. Instruments were removed in the three patients with late presentation who had solid fusion at operation. Viable bone graft and instrumentation were left in situ in all patients who were seen before fusion. All wounds healed without sequelae, except for three that required flap closure. Pseudarthrosis was noted in three patients after more than 1 year of follow-up in this series. Postoperative spinal wound infection is a potentially devastating problem. In this series, infection was more common in patients undergoing fusion with instrumentation and in patients with cancer metastatic to the spine. An aggressive surgical approach, including repeated debridement followed by delayed closure, is justified. Instrumentation may be safely left in situ to provide stability for fusion.

We report a man in whom a 15 cm. renal tumor was excised at the age of 49. The pathological examination showed a clear cell carcinoma. Five years later, he presented with headache, vomiting and unilateral palpebral ptosis. Imaging studies showed a sellar tumor with pituitary apoplexy. The tumor was excised and the pathological study disclosed a clear cell tumor, positive for vimentin, cytokeratins AE1 and AE3 and immunohistochemically negative for LH, TSH, ACTH and GH. Considering the similar histopathological features, it was considered as a metastasis of the renal tumor. The patient was supplemented with thyroid, adrenal and gonadal hormones. Seven years later, he presented a new tumor in the remaining kidney, that corresponded to a cystic papillary renal cell carcinoma. Afterwards, he presented a transitional urinary bladder tumor. Mortality associated to renal cell tumors is 90% at 5 years, and pituitary metastases are extraordinarily uncommon.

Painless unilateral proptosis is a frequent manifestation of numerous orbital neoplastic and non-neoplastic processes. Various mesenchymal tumors of both fibrohistiocytic and vascular origin are well-described causes. Solitary fibrous tumors (SFTs) are rare spindle-cell neoplasms usually found associated with serosal surfaces, especially the pleura, but they have recently been described in a number of extrapleural sites including the orbit. The authors describe the case of an 18-year-old man who presented with a 6-month history of painless proptosis in the right eye. A visible nontender mass in the right supermedial orbit producing ptosis of the upper lid was present. Magnetic resonance imaging (MRI) showed a well-circumscribed soft tissue mass located above the right globe with no obvious invasion of adjacent orbital structures. Uneventful surgical excision through a right frontal-orbitotomy approach was performed. Histological evaluation showed a solid, highly vascular tumor mass composed of spindle cells arranged in short ill-defined fascicles. Intense immunohistochemistry staining for CD34 and B-cell lymphoma 2 (BCL-2) differentiated the lesion from the more common hemangiopericytoma. Though considered benign, local recurrence and extraorbital extension of orbital SFTs have been described. Malignant behavior, including distant metastases, has been documented in as many as 20% of pleural cases with mortality rates as high as 50%. The natural history of this tumor in the orbit is unclear. The authors report the 35th case of orbital solitary fibrous tumor and discuss the differential diagnosis, histopathology, radiological features, and clinical course.

A 17-year-old boy diagnosed with an alveolar rhabdomyosarcoma involving the perineum and with extensive lymphadenopathy was treated with chemotherapy yet developed metastases to the head and neck 6 months into therapy. Ten months after initial diagnosis, while receiving salvage chemotherapy and radiotherapy, he returned with pain on movement of his left eye, proptosis, and ptosis of the left upper eyelid. Computed tomography (CT) revealed a mass within the left lateral rectus muscle that biopsy confirmed to be metastatic alveolar rhabdomyosarcoma. Despite continued chemotherapy and radiotherapy, he ultimately died of the disease. Alveolar rhabdomyosarcoma from distant sites rarely metastasizes to the extraocular muscles. However, our case shows that alveolar rhabdomyosarcoma may metastasize to the orbit and involve a single muscle.
