Two cases of primary intracerebral malignant lymphoma were reported. Case 1 was a 42-year-old man who had been suffering from headache and mental disturbances for about 3 months prior to admission. These complaints progressed insidiously. He was admitted to our hospital on March 31, 1973. On neurological examinations he was in somnolence state and had neck rigidity, positive of Kernig's sign, disorientation and dyscalculia. Lumbar puncture gave a C.S.F. pressure of 240 mmH2O and the fluid contained 180 mg/dl of protein. A left vertebral angiogram via brachial artery demonstrated thalamic and cerebellar mass lesions. For the development of symptoms of increased intracranial pressure, a ventriculoperitoneal shunt operation was performed on April 7. A right carotid angiogram after ventriculoperitoneal shunt operation disclosed a frontal mass lesion. On May 2, a right frontal craniotomy was carried out and the frontal lobe was removed together with the tumors. After the operation his consciousness remained stupor. Thereafter consciousness and clinical pictures gradually worsened, and he died on May 30. Autopsy was performed, and gross examinations revealed tumors in the bilateral frontal and temporal lobes, right parietal lobe, and left cerebellar hemisphere. On coronal sections, there were neoplastic proliferation extending from the right thalamus to the putamen and a tumor in the right midbrain. No evidence of neoplastic proliferation was found outside the central nervous system. Microscopic examinations showed a diffuse proliferation of tumor cells with mitosis and polymorphism. The tumor was consisted of small lymphoid cells. Reticulin fibers were not found in the tumor with Watanabe's silver method. It was also unable to impregnate the tumor cells with silver carbonate. This case may be classified the primary interacerebral lymphosarcoma. Case 2 was a 48-year-old man, who was admitted to the hospital complaining of occipitalgia, speech disturbances and diffculty in walking. On neurological examinations, he had a right spastic hemiparesis and dyscalculia. A right carotid angiogram showed the frontal mass lesion. On April 18, a left frontal craniotomy was performed and frontal lobe was removed with the tumor. He made a good recovery from the operation and remained well for about 1 month. However, it culminated in a gradual diminution in the level of consciousness. Unfortunately, he died on June 20. No autopsy was performed. Histologically, the tumor cells had round or ovoid nuclei, mitosis and polymorphism. The perivascular arrangement of the tumor tissue showed tendency to confluence. There were reticulin fibers in the tumor tissue, particularly around the blood vessels. Microglial cells were not impregated with silver carbonate. It is supposed that this case belongs to the primary intracerebral "reticulum cells sarcoma-microglioma" described by Rubinstein or reticulum cell sarcoma. Both the case 1 and the case 2 should be filed to be malignant lymphoma in the wide category.

A three-year-old boy with a progressive history of headache, vomiting and ataxia in the course of 2 months, was admitted on August 1983, when he was lethargic. Neurological examination revealed dysphagia, scanning speech and tremor in the bilateral hand. CT scan showed a very large enhanced mass in the center of posterior fossa with central necrosis in it and the dilatation of whole ventricular system. Suboccipital craniectomy was immediately performed and the tumor that occupied the vermis and invaded into both cerebellar hemisphere was subtotally removed. Postoperative irradiation was well performed: 4140 rads to the whole brain and 3162 rads to the spinal cord. However, 5 months later, facial palsy in the left side and progressive ataxia became prominent. CT scan showed multiple enhanced masses in the left trigonum and right anterior horn of the lateral ventricles and in the left cerebellopontine angle. In spite of chemotherapy, the patient had a down-hill course, especially after the ventricular hemorrhage, and died on June 9th, 1984. Histologically, the tumor had a lobulated appearance with an aggregation of tumor cells encircled by vascular septae. The cells within lobules generally had vesicular nuclei, which were arranged in parallel row. Occasionally smaller hyperchromatic cells with scant cytoplasm were present along the vascular septae. Reticulin was present within the septa, but was not observed within the lobules. Scattered astrocytic cells and processes were identified within the lobules by the immunoperoxidase technique for GFAP. The fibrillary cytoplasmic processes within the lobules were stained by immunoperoxidase technique for neurofilament (68K).(ABSTRACT TRUNCATED AT 250 WORDS)

Primary Immune thrombocytopenia or idiopathic thrombocytopenic purpura (ITP) is an acquired immune disorder presenting with abnormal hemorrhagic symptoms resulting from a decrease in the number of platelets. The disorder used to be attributed to increased destruction of platelets mediated by antibodies. In the past few years, the description of its etiopathology has changed. A deficiency in the marrow production of thrombocytes has been demonstrated; because it is associated with increased peripheral platelet destruction, the deficiency cannot be compensated. These findings have justified the realization of studies assessing the utility of second generation thrombopoietin analogues for the treatment of these patients. These drugs include romiplostim or AMG 537 (Nplate), a peptidic analogue that stimulates the thrombopoietin receptor and induces an increase In the production and differentiation of megakaryocytes. Data obtained from the clinical trials that led to the authorization and subsequent follow-up describe romiplostin as an effective and safe drug for adult patients with chronic ITR The overall response rate is 94%; despite variations in the levels of platelets throughout treatment, 50% of patients maintain the response 95% of the time, and 78% of patients discontinue or significantly reduce the use of rescue treatment. The most common adverse event is headache. Reticulin fibrosis has been described, which is reversible after treatment discontinuation.
