The pathophysiology of cerebral tumor mass in cases of systemic non-Hodgkin's lymphoma is not well known. We experienced with two cases with this lesion. The purpose of this report is not only case presentation but also an analysis of cases from the literature from the clinical, radiological, histological, immunological and therapeutic aspects. Case 1 was a 82-year-old man who had weakness in the right arm and for the past month. For about two years he had been received anticancer chemotherapy because of a systemic malignant lymphoma at another hospital. Neurological examination revealed disorientation and right hemiparesis. Microscopic and immunological studies of the biopsy specimen of the enlarged supraclavicular node showed a non-Hodgkin's B-cell lymphoma of the diffuse large cell type according to the Lymphoma Study Group (LSG) classification. The clinical stage (CS) of the lymphoma was IV except for the CNS lesion by systemic examination including lymphography. CT scan on admission revealed remarkable enhancement of a nodular high density area near the lateral ventricle, accompanied by surrounding low density. Angiography failed to reveal a tumor stain. CSF cytology was positive although no pleocytosis was observed. Case 2 was a 70-year-old man who had weakness of the right foot for two weeks. About three years ago he underwent orchiectomy for a testicular tumor at another hospital. Neurological examination revealed disorientation, memory loss and right hemiparesis.(ABSTRACT TRUNCATED AT 250 WORDS)

Primary adrenal lymphoma (PAL) is a very rare disease and usually does not have disease elsewhere, and if present, it is frequently extranodal. Several cases of PALs, with central nervous system (CNS) involvement, gastrointestinal tract or other endocrine organs involvement, have been reported in Western literature. We experienced a case of PAL with CNS involvement, which was previously unreported in Korea. The patient, a 61 year-old male, was admitted with left abdominal pain. After imaging study and needle aspiration biopsy (NAB), a bilateral primary adrenal lymphoma (large B-cell type), with bilateral hemorrhage, was confirmed. Combination chemotherapy, with CEOP regimen, was used. A follow-up abdomino- pelvic CT scan, after the second CEOP chemotherapy, showed the previous adrenal masses had nearly disappeared. However, about 2 months after diagnosis (day 52), he showed recent memory loss, obtundation, disorientation and drowsy mental status. The brain MRI revealed multifocal scattered lesions with increased signal intensity. The result of a brain biopsy was diffuse large B-cell lymphoma. After 5(1/2) cycles of chemotherapy, with CEOP regimen, and whole brain radiotherapy, he is still surviving 6 months later, and has become alert with nearly normalized cognitive function.

A 75-yr-old male simultaneously having lymphoplasmacytic lymphoma (LPL) and diffuse large B-cell lymphoma (DLBCL) is presented. He had manifested with lumbago, high-grade fever, and confusion. Physical examination on admission showed disorientation and severe back pain. There were neither lymphadenopathy nor hepatosplenomegaly. Routine laboratory tests showed moderate pancytopenia, hypercalcemia (serum calcium, 15.9 mg/dL), IgM lambda-type monoclonal gammopathy (IgG, 405 mg/dL; IgA, 42 mg/dL; and IgM, 2023 mg/dL), and lambda-type Bence-Jones protein in the urine (0.8 g/d). Bone marrow biopsy showed the clusters of surface lambda-positive small-sized mature-appearing lymphoplasmacytoid cells. Bone survey and computed tomographic scan showed multiple osteolytic lesions and a tumor involving the third lumbar spine (L3). An open biopsy of the L3 tumor showed diffuse proliferation of CD20- and lambda-positive large cells. We thus diagnosed the patient as simultaneously having LPL and DLBCL. Although the combination chemotherapy was at least partially effective, he died of bacteremia and organ failure after three courses of chemotherapy. To clarify the clonal relatedness between LPL and DLBCL, we analyzed the sequences of the complementarity-determining region 3 in immunoglobulin heavy-chain genes. The data showed that LPL and DLBCL in the present patient originated from two independent clones.

An 82-year-old man without notable medical history was admitted to our hospital following subacute deterioration of apettite, disorientation and strange behavior. There was spasticity of the right extremities without weakness. LDH and serum soluble IL2 receptor antibody levels were elevated, and as well as the protein level and IgG levels in the cerebrospinal fluid. CT scanning of the brain revealed a lesion at the left corona radiata. The patient's level of consciousness was worsening, and follow-up study of the brain showed a new lesion in the left occipital lobe. Intravascular lymphomatosis was therefore suspected. We performed a skin biopsy from two typical senile angiomas. In one of these biopsy specimens, a capillary hemangioma was present in the mid-reticular dermis and it was filled with abnormal B cells. The diagnosis of intravascular B cell lymphoma (IVL) was thus established. IVL is a rare subtype of extranodal diffuse large B cell lymphoma with a poor outcome. However, it is recently thought that if the diagnosis is established early, aggressive chemotherapy increases survival. Senile angioma is a skin eruption that is considered prevalent for the most part in elderly people. If a patient is suspected to have IVL, and there is no appropriate site of biopsy, it might be beneficial to try a skin biopsy aiming at senile angiomas for early diagnosis.

We describe the clinicopathological features of a patient with an autopsy-proven primary CNS lymphoma, who had a relatively long remission period after onset. A 61-year-old man experienced disorientation and gait disturbance. A ventriculoperitoneal shunt operation was performed, based on the diagnosis of hydrocephalus due to aqueductal stenosis, after which his symptoms subsided. Three months later, T2-weighted magnetic resonance imaging (MRI) revealed high-intensity lesions in the corpus callosum and tectum. However, he remained asymptomatic for the next three and a half years, during which periodic MRI studies constantly detected the lesions. At the age of 65 years, he suffered respiratory and consciousness disturbances, and his general condition gradually deteriorated. MRI studies disclosed that the callosal lesion had spontaneously disappeared, whereas the tectal lesion had developed to become an enhanced linear lesion with a tendency to spread on the dorsal side of the brain stem. Examination of the cerebrospinal fluid disclosed a markedly elevated beta2-microglobulin content, and a tentative diagnosis of malignant lymphoma was made. Steroid pulse therapy had little effect, and the patient died four years after presentation. Examination at autopsy disclosed a malignant, large B-cell lymphoma that had diffusely infiltrated the cerebrum and brain stem. In the corpus callosum, a small number of residual lymphoma cells were seen around the vessels. Therefore, the initially detected lesions in the corpus callosum and tectum might have been attributable to lymphoma, and the unusual clinical and radiological features of this case provide further information that might aid in diagnosis and help to ensure prompt treatment.

A 56-year-old man presented with fever, disorientation, and testicular pain. He was receiving azathioprine immunosuppression for autoimmune hepatitis. Orchiectomy identified occlusion of spermatic cord vessels by intravascular large B-cell lymphoma (IVLBL) and ischemic changes in the testis. Tumor cells were positive for CD 10, CD 20, CD 30, and Epstein-Barr virus (EBV) latent membrane protein 1 (LMP-1) and early region RNA (EBER). He was treated with the cessation of azathioprine, chemotherapy, anti-CD 20 immunotherapy, and radiotherapy. Twenty months after diagnosis, he is alive with no evidence of lymphoma or hepatitis. This is the first report of IVLBL presenting with testicular ischemia. It highlights the importance of prompt diagnosis and intervention to achieve durable response. That this lymphoma arose in the setting of immunosuppressive therapy introduces additional complexity relating to pathogenesis, clinical behavior, and treatment.

A 31-yr-old man presented with a 1-wk history of fever, chills, weakness, headaches, and a significant 20-lb weight loss over the preceding 2 months. His past medical history was relevant for liver amebiasis during childhood. Two days before admission, the patient noticed jaundice. He denied abdominal pain or other GI symptoms, and there was no history of alcohol intake, medications, or illicit drugs. His physical examination revealed generalized jaundice, hepatosplenomegaly, and bilateral leg edema. Neurologically, the patient was agitated, with periods of disorientation, and he had bilateral flapping. His blood tests revealed pancytopenia, renal failure, liver failure, and coagulopathy. Because the patient had a fever, hepatosplenomegaly, and pancytopenia, a further workup also included a bone marrow and liver biopsy. No conclusive diagnosis could be made from the above tests, and the patient died 5 days after admission. Postmortem evaluation, including flow cytometry and gene rearrangement in the tissue obtained from the liver, revealed large B cell lymphoma. This case illustrates an unusual presentation of hepatic non-Hodgkin's lymphoma. Current information regarding this entity is scant, mainly owing to its rarity. We present a review of the literature, including the incidence, presentation, treatment, and prognosis of primary hepatic lymphoma.

We present a patient with primary central nervous system B-cell lymphoma. He had suffered from slowly developing weight loss and presented to us with disorientation, seizures, and a supranuclear gaze disturbance. The patient was dismissed with the primary diagnosis of autoimmune encephalitis of the brainstem and put on oral corticosteroids. Four months later, his health status had deteriorated, and at that time diagnostic methods pointed to a cerebral lymphoma. Stereotactic biopsy with subsequent immunohistochemistry and polymerase chain reaction analysis revealed a highly malignant B-cell lymphoma of the CNS, despite prolonged corticosteroid treatment. The patient was treated with whole brain radiotherapy.

A 73-year-old male presented with diffuse mixed B cell lymphoma with involvement of the central nervous system (CNS) and testis manifesting as mild disorientation and aphasia. A left frontal cerebral mass and a right testicular tumor were found, and both lesions were surgically resected. Histological examination revealed diffuse mixed B cell type malignant lymphoma in the CNS and testis. The patient received irradiation to the head, and his initial symptoms improved. Pelvic computed tomography revealed enlargement of the contralateral testis and prostate. Needle biopsy confirmed lymphoma. The patient died 5 months after the initial diagnosis of septic shock. Autopsy examination revealed lymphoma cell invasion of the lung, bone marrow, prostate gland, and thalamus, but without involvement of the systemic lymph nodes. In a patient with an intracranial lymphoma, it is important to determine if the lesion is primary or metastatic and to plan medical treatment including systemic chemotherapy as soon as possible. Improvement of the prognosis of systemic non-Hodgkin's lymphoma with CNS involvement requires the detection and effective treatment of systemic lesions as well as the control of the CNS lesions.

A 67-year-old female was admitted to our department with difficulty in speech, disorientation, memory loss and seizures. Blood laboratory tests revealed diabetes insipidus. This patient had been treated with steroids for systemic lupus erythematosus (SLE) for 30 years. Due to this treatment neurological symptoms had been understated causing a long delay in performing ulterior researches. A brain MRI revealed a mass lesion in the hypothalamic area. A biopsy was performed and histopathological diagnosis was malignant large B cell lymphoma. Subsequently, she received methotrexate therapy but died of pneumonia during the second cycle. Primary central nervous system lymphoma in association with SLE is a rare occurrence but it should be considered in the diagnostic process when neurological symptoms occur. A brain MRI must be performed and corticosteroids should be interrupted. A biopsy of the cerebral mass lesion permits diagnosis and appropriate therapy may be administered.
