The presentation, treatment, and outcome of 12 patients with high-grade neurogenic sarcoma (NS) of the extremity were compared with those of 21 patients with high-grade extremity soft-tissue sarcoma of nonneural origin in a retrospective study from January 1976 to January 1988. Pain and neurologic deficit were more common in the NS group. Limb-sparing surgery was carried out with equal frequency in both groups. Local recurrence was six times more frequent in the NS group at three-year follow-up (59% vs 10%). Width of resection margin was the dominant prognostic variable bearing on local control after limb-sparing surgery. Anatomic and functional constraints tended to limit resection margin in patients with NS arising from mixed motor-sensory or predominantly motor nerves.

The natural history of cauda equina tumors was studied in 13 patients. Pain was the most prominent clinical manifestation. Neurological dysfunction mainly consisted of sensory disturbances. The pre-operative course was in 62% three years or longer. A relation was found between the histology of the tumor and the delay of diagnosis: ependymomas were discovered much later than schwannomas. Other histological types of tumors were meningioma, sarcoma and metastasis of a medulloblastoma. The effect of treatment, in nine cases only surgical, was excellent in seven of the 13 patients. The prognosis was determined by histology and length of pre-operative period.

A relapse of acute nonlymphocytic leukemia in a child presented as subacute mononeuropathy involving the sciatic nerve. Surgical exploration showed a chloroma (granulocytic sarcoma) of the distal sciatic nerve, but resection and irradiation did not lead to recovery of nerve function or complete resolution of the patient's symptomatic neuropathic pain. This case represents a rare neurologic complication of what is currently an uncommon presentation for leukemic relapse, and may be the only reported case of chloromatous involvement of the peripheral nervous system (PNS) without coexisting epidural or leptomeningeal leukemia.

A 34-year-old man developed a spindle-cell sarcoma originating in a preexisting lesion of monostotic fibrous dysplasia. A review of the literature reveals 83 cases of a malignant degeneration in fibrous dysplasia; osteosarcoma was the most common type of tumor. The next most common were fibrosarcoma and chondrosarcoma. The malignant tumor usually developed in the third or fourth decade of life. The most frequent anatomic sites were the craniofacial bones, the femur, and the tibia. Twenty-three of the 83 cases were treated with local radiation. In fibrous dysplasia, any abrupt alteration in the clinical course, manifested by pain and swelling, raises the possibility of malignant degeneration.

Chordomas are slowly growing malignant tumors arising from notochordal rests. They are occurring in adults (50 to 60 year old) and are mainly (85%) located in sacrococcygeal or spheno-occipital regions; other main localization is cervical spine. Chordomas are usually discovered in patients with pain or symptoms due to compression of surrounding viscera. Radiologically it is characterized by association of osteolysis and soft tissues opacity. On macroscopic examination tumoral tissue has mucoid appearance; under microscope it is made up with lobules of epithelial-appearing cells surrounded by acid mucosubstances. Tumorous cells contain glycogen and neutral mucosubstances. They are surrounded by argyrophilic rim due to pericellular condensation of intercellular matrix, well viewed on electron microscope examination. When their cytoplasm is filled with vacuoles, cells take up typical physaliphorous appearance. Chordomas cells express epithelial differentiation antigens (low molecular weight cytokeratins, EMA, CAM 52, HFM 62, even CEA), Vimentin and S-100 Protein: this triple positivity allow differentiation between chordomas and numerous others tumors. Correct treatment of chordoma is achieved with an initially complete excision. Local recurrences are frequent and sometimes inoperable: in this cases radiotherapy alone may be performed (70 grays). Sarcomas (fibroblastic or Malignant fibrous histiocytoma) may occur after radiotherapy or without it. Hematogenous metastasis occur in 10% to 15% of patients. Survival rate at five years is included between 50% and 75%. Chondroid chordoma is a special entity occurring in younger patients (35 year old) and located in spheno-occipital region. In addition to chordomas it contain chondroid (benign or malignant) islands. Mean survival rate (16 years) is far better than for chordoma or chondrosarcoma.

The case history of a 53-yr-old woman exhibiting the progressive appearance of several hundreds of subcutaneous leiomyomatous tumors in a 15-yr period is presented. The occurrence of multiple tumors in the gastrointestinal tract, mesentery, and retroperitoneum, necessitated several laparotomies because of pain and chronic blood loss. On light microscopy high mitotic activity, which is generally a characteristic of sarcoma, was only encountered in lesions, surgically removed a few months before death. It is argued that our patient suffered from multiple leiomyomatous tumors with progressive growth capacity, which may represent a multifocal origin rather than a metastasized sarcoma.

Symptomatology in thirty patients with hydatid cyst of kidney treated in the Urologic Clinic, UHC, Avicenne, Rabat, was florid (83% with pain and 43% with a mass in the flank) and sometimes specific (27% of cases). Associated hypertension was an exceptional finding. Preoperative diagnostic investigations included ultrasound and CT scan imaging, replacing arteriography to a great extent. Approach to surgical treatment was usually by a lombotomy (64%) or even a Baraya incision (23%), followed by treatment of the renal cyst itself (a case of silent kidney on IVU treated by resection of a protruding dome). Nephrectomy was frequently necessary (47%) for renal lesions. When conservative therapy appeared sufficient the only procedure adopted, apart from specific cases, was resection of a protruding dome even when the hydatid cyst was discharging into excretory pathways. Splenectomy was sometimes necessary (2 of 22 cases) for hydatid cyst of left kidney. This series emphasizes the safety of surgery for hydatid cyst of kidney since the only death reported occurred 2 months after operation in a patient with an associated renal sarcoma.

A 2-year-old boy had intermittent pain and mottling of the left thigh. Swelling of the vastus lateralis developed, and a biopsy revealed proliferative myositis. The pathogenesis is unknown, but trauma and ischemia have been implicated. The rarity of proliferative myositis in children, and the possibility of mistaking the lesion for a sarcoma make the case noteworthy.

23 patients were treated for soft-tissue sarcoma at "Allgemeines Krankenhaus Heidberg, Hamburg", between 1963 and 1983. Their courses were analysed for this report, with findings being compared to literature data. "Unclassified sarcoma" accounted for the majority of cases hospitalised for treatment, in the period under review. Male and female patients were equal in number. Incidence rates were at their highest in the fifth and seventh decades of age. Most of the primary lesions were recorded from the lower extremities. Painful or indolent swelling was the first clinical symptom in most of the patients involved. The best therapeutic results were achieved by radical surgery. Postoperative radiotherapy did not improve the therapeutic results obtained from operations on the cases reported in this study. Metastases developed in 8 patients, following different primary therapies. Five-year survival rates were found to depend on histological aspects, primary therapy, and number of recurrences.

During a 37-year period, 26 patients were seen who had chondrosarcoma with additional mesenchymal components ("dedifferentiated low-grade chondrosarcoma"). Sixteen were men and 10 were women aged 30 to 85 years (median, 61 years). The tumors' chondroid areas were of borderline or low-grade malignancy. The additional mesenchymal component was histologically classified as malignant fibrous histiocytoma (16), rhabdomyosarcoma (4), low-grade fibrosarcoma (3), osteosarcoma (2), and undifferentiated sarcoma (1). Preferred locations were pelvis (10) and femur (8). Symptoms had been present for 1 year or less in most cases. Pain was the most common symptom. In 15 of 26, major amputation was the primary treatment. Twelve patients received chemotherapy, usually after developing metastatic disease, but only one achieved a partial response. Median disease-free interval after diagnosis was 4 months, median survival was 6 months, and 19 patients died within 1 year. Of 4 who survived longer than 18 months, 3 presented with a low-grade fibrosarcoma. Survival and development of metastasis appeared unrelated to cell type, initial treatment, or chemotherapy, except when the tumor's initial nonchondroid component was low-grade fibrosarcoma.
