A rare case of spinal epidural granulocytic
sarcoma
(GS) preceding acute myelogenous leukemia is described. A 10-year-old boy presented with lower leg
weakness
. The initial diagnosis was a histiocytic lymphoma, and he was treated accordingly. No evidence of bone marrow involvement was found at that time. The correct diagnosis of epidural GS was made possible in retrospect by using immunoperoxidase staining for lysozyme fourteen months later when the patient showed the full-blown features of leukemia. This rare tumor should be considered in the differential diagnosis of an epidural mass with cord compression in patients with or even without acute leukemia, because early diagnosis followed by appropriate combined chemotherapy and radiation may obviate surgical intervention and eventually prevent leukemic transformation.

Acute encephalopathy following treatment with ifosfamide and mesna was observed in 5 (4 women and 1 men) of 28 patients (17.8%), with advanced
sarcoma
, lymphoma or ovarian carcinoma. This appeared within 2 to 7 days following the first dose of ifosfamide treatment, and included mental status changes, urinary incontinence,
weakness
, seizure activity, altered consciousness and psychiatric manifestations. Three cases were fatal, while two patients recovered completely. Brain CT and morphometric studies were normal in all the patients. Associated findings were myelosuppression, renal failure and electrolyte alterations.

Nearly 25% of all primary neurogenous tumors arise from peripheral nerves in the head and neck. The extracranial parts of the facial nerve, however, rank low as potential sites. Their tumors nonetheless pose diagnostic and management problems. In the intraparotid location the neurogenous tumors most often present as mass lesions, accompanied, in one third of patients, by various degrees of facial
weakness
. With the exception of a peculiar predilection of childhood plexiform neurofibromas to afflict the facial nerve, the majority of the tumors are neurilemomas. Recurrences are unusual after surgical removal of either neurilemomas or neurofibromas. The rare facial nerve
sarcoma
is a high-grade malignancy.

The case records of and histopathologic findings in 57 dogs with nonangiogenic and nonlymphomatous splenic sarcomas were reviewed. Splenic neoplasms in these dogs included leiomyosarcoma, fibrosarcoma, undifferentiated
sarcoma
, liposarcoma, osteosarcoma, chondrosarcoma, myxosarcoma, rhabdomyosarcoma, and fibrous histiocytoma. The clinical signs associated with splenic
sarcoma
included anorexia or decreased appetite, abdominal distention, polydipsia, lethargy, vomiting, weight loss, and
weakness
. An abdominal mass was detected in 86% of the dogs by use of abdominal palpation (63%), and/or abdominal radiography (74%). The diagnosis was based on histopathologic findings in the spleen. Abdominal exploratory surgery was performed on 43 of the 57 dogs. Twenty-seven dogs were treated by splenectomy, and 16 were euthanatized at the time of surgery because of widespread metastatic lesions. Of the 14 dogs on which surgery was not performed, 11 were euthanatized on the basis of results of preoperative diagnostic tests, and the remaining 3 dogs had splenic neoplasms that were incidental findings at necropsy. Of the 27 surgically treated dogs, 5 died in the immediate postoperative period, 12 died or were euthanatized within 1 year after splenectomy, and only 5 dogs survived greater than or equal to 1 year. Three dogs were lost to follow-up evaluation, and 2 were still alive 6 and 7 months after surgery. The median survival time of the 22 dogs for which survival was known was 2.5 months. The median survival time for 11 dogs with no obvious metastasis at the time of splenectomy was 9 months.(ABSTRACT TRUNCATED AT 250 WORDS)

A 12-year-old boy with acute myelogenous leukemia developed acute
weakness
and paresthesias of the lower extremities after lumbar puncture. Computed tomography and magnetic resonance imaging revealed 2 large paraspinal masses (granulocytic
sarcoma
) causing spinal cord compression. Treatment with corticosteroids, radiation therapy, and chemotherapy caused complete resolution of symptoms; there was no evidence of tumor on subsequent magnetic resonance imaging or at autopsy. Granulocytic sarcomas (chloromas) rarely involve the nervous system in patients with acute myelogenous leukemia, although with increased survival it is apparent that the incidence may be greater than previously believed. Central nervous system prophylaxis was not administered to our patient but may be recommended for future patients if systemic disease can be controlled. General features of central nervous system complications of acute myelogenous leukemia, characteristics of granulocytic
sarcoma
, and review of current radiographic techniques used in the evaluation of these tumors are discussed.

More than 1,900 patients of advanced and inoperable malignant tumor were treated with fast neutron radiotherapy using 30 MeV (d-Be) and 14 MeV (d-Be) beams at NIRS and IMS between 1975 and 1986. Protocols were largely nonrandomized. Some results have been obtained: 1) results with mixed beam studies for advanced squamous cell carcinoma of the uterine cervix have been equivocal compared with the photon controls. 2) some trends of local control have been observed in the trial of esophageal cancer, early cases of adenocarcinoma of the lung and malignant melanoma. 3) significant better results were observed in the pancoast type lung cancer and osteo
sarcoma
which was treated by the systemic multimodal treatment. It is concluded that neutrons are efficacious for certain specific tumor types owing to some biological effects, however the problem of inferior dose distribution was the
weakness
of neutron therapy at present.

A 13-year-old boy presented with progressive bilateral lower limb
weakness
due to exradural granulocytic
sarcoma
of the spine. After surgical decompression and radiotherapy, he remained in complete remission 6 years after initial diagnosis. The possible reasons for the favorable outcome of this unique case are discussed.

A 6-year-old Golden Retriever was referred for evaluation of hind limb paresis and
generalized weakness
. Neurologic examination revealed multifocal cervical and lumbosacral spinal disease. Radiography and myelography failed to identify a lesion. Cerebrospinal fluid was markedly cellular and had a high protein concentration, consistent with myelitis or a neoplastic process. The dog did not improve with medical management. Gross and histologic examination of the brain and spinal cord revealed a thick meningeal surface characterized by polymorphic histiocytic-like cells to multinucleate giant cells. The neoplastic process was considered to be a disseminated meningeal polymorphic cell
sarcoma
.

FBJ osteosarcoma virus (FBJ-MSV) isolated originally from a spontaneously arising osteosarcoma in a CF1 mouse is the only known naturally occurring murine
sarcoma
virus (MSV). It is unique among strains of MSV in producing primarily sarcomata in mice. The capacity of tumour cells transformed in vivo by this agent to elicit specific transplantation immunity in syngeneic hosts was investigated. A low level of resistance (10(4)-10(5) cells) was consistently induced by implantation of x-irradiated (15,000 rad) tumours or surgical excision of developing subcutaneous grafts. By contrast intraperitoneal inoculation of virus containing cellfree extracts of FBJ-MSV sarcomata was a far less effective immunization procedure. Confirmatory evidence for the antigenicity of these neoplasms was obtained in tests in which preincubation of tumour cells with lymphoid cells from specifically immune donors inhibited in vivo outgrowth of the FBJ-MSV cells in untreated syngeneic recipients. The induction of host resistance to FBJ-MSV cells by immunization with identical and independently-induced FBJ-MSV tumours established that FBJ-MSV cells possess common cell surface antigenic specificities in a manner analogous to those of experimental neoplasms induced by other oncogenic DNA and RNA viruses. Since FBJ-MSV cells release infectious virus it was not possible in this system to establish whether the tumour-rejection antigen was cellular or virion in nature. The antigenic
weakness
of FBJ-MSV cells in syngeneic hosts is comparable with that of virus-induced murine leukaemias of the Gross (G) or "wild" type subgroup to which category FBJ-MSV also belongs. These features suggest that FBJ-MSV exemplifies naturally occurring sarcomagenic viruses more closely than those of the Friend-Moloney-Rauscher-Graffi (FMRGr) subgroup which in general induce highly antigenic neoplasms.

A case of vitamin D resistant hypophosphatemic osteomalacia associated with osteosarcoma of the mandible is presented. The patient complained of lumbar, knee and foot pain and muscle
weakness
of two years' duration. Serum phosphorous was 1.0-1.6 mg/dl, tubular reabsorption of phosphorus was 47 to 58%, TmPO4/GFR was o.7-1.2 mg/dl. Aminoaciduria was noted. Bone biopsy confirmed the diagnosis of osteomalacia. He partially responded to the treatment with 1 alpha()H) D3 and sodium phosphate. After removal of
sarcoma
of the mandible, symptoms remitted and pertinent laboratory data became normal except serum alkaline phosphatase for more than one year without treatment. It is suggested that an impaired response of the tubule and bone to active vitamin D3, caused in some way by the osteosarcoma might be one of the causes of osteomalacia in this case.
