A 48-year-old woman was admitted with neck tumors and cutaneous nodules. On the histological basis of the skin nodule biopsy, a metastatic anaplastic carcinoma was suspected. Immunohistochemical studies showed the presence of Ki-1 antigen, IL-2 receptor antigen, leukocyte common antigen (LCA), CD3 and CD4 on the tumor cells compatible with Ki-1 positive anaplastic large-cell lymphoma. This case was, however, finally diagnosed as adult T cell lymphoma (ATL) of a helper/inducer phenotype. She was born in Kagoshima. The serum anti-ATL associated antigen (ATLA) was positive. Southern blot analysis on the DNA extracted from the skin tumor cells showed a monoclonal integration of HTLV-1 proviral DNA. The results suggested that Ki-1 positive lymphomas may include a subset of ATL with a large-cell histology.

A 66-year-old female suffering from HTLV-1 associated myelopathy (HAM) for more than 30 years was hospitalized because of memorial impairment, deafness, dysarthria, dysphagia, and complete paraplegia. She first noticed stiffness and weakness of the right leg at 35 years of age. Gait disturbance was slowly progressed and complete paraplegia developed 18 years later. Neurological examinations on admission revealed that she was bedridden with decubitus, mental deterioration (pre-dementia of subcortical type), bilateral optic nerve atrophy, severe sensory-neural deafness, dysarthria, complete paraplegia, and marked neurogenic bladder. Laboratory data showed mild normocytic anemia and moderate diabetes mellitus. Anti-HTLV-1 antibody titers in serum and CSF were 78,192X and 1,024X, respectively (PA method). Serum levels of soluble IL-2 receptor was markedly elevated (2,200 U/ml). Peripheral blood lymphocytes showed spontaneous proliferation when cultured for 5 days (3H-thymidine uptake; 45,285 cpm/5 X 10(4) cells). MRI examinations of the spinal cord disclosed a predominant atrophy of lower thoracic cord without any compressive lesions. Brain MRI showed diffuse high intensity lesions of the periventricular area on T2 weighted images. Such abnormalities were predominantly found in fronto-parietal region and were quite similar to those of leuko-ariosis. Single photon emission CT using 123I-iodoamphetamine showed hypoperfusion of cerebral white matter on delayed image. It has been reported that intellectual impairment and brain atrophy are not usually seen in HAM patients. The present case, however, shows that such abnormalities of the central nervous system could occur in HAM patients with a long duration of illness.

We report a rare case of adult T cell leukemia/lymphoma (ATLL) in which cardiac invasion was clinically demonstrated and treated effectively. A 45-year-old female was admitted because of exertional dyspnea and cervical tumors. The leukocyte count was 19,100/microliters with 20% of flower cells. HTLV-I antibody was positive. She was diagnosed as ATLL and treated with VEPA. She got remission for a short duration which was followed by relapse. OPEC was started as salvage therapy. In the course, extensive pericardial effusion was found in chest X-P. Pericardial puncture demonstrated ATLL cells and high titer of free IL-2 receptor (57,400U/ml) in the effusion. It was diagnosed as pericardial invasion of ATLL cells. Chemotherapy was started with new combination of drugs (cisplatin, mitoxantrone, ifosfamide, and prednisolone). Concomitantly pericardial drainage was performed and the drugs were administered directly into the pericardial cavity. The clinical improvement was obtained and pericardial effusion did not appear thereafter. She died 4 months after the diagnosis of cardiac invasion. On autopsy myocardial invasion was identified. The pericardium widely adhered and effusion measured 42 ml.

A 59-year-old woman with a large nodular ulcerative lesion on her neck was presented. She had a 3 year history of recurrent cutaneous nodules which spontaneously regressed before regional lymphadenopathies appeared. She has followed an indolent clinical course for seven years after the first overt lymphadenopathies appeared. Histological findings were compatible with anaplastic large cell lymphoma (ALCL). The tumor cells strongly expressed Ki-1 (CD30), HLA-DR, IL-2 receptor (CD25) and leukocyte common antigen. These findings led to the diagnosis of primary cutaneous Ki-1+ ALCL. Although the majority of the tumor cells did not express T-cell related antigens, the detection of monoclonal TCR gene rearrangement clearly established the T-cell lineage nature.

We report on an elderly patient with a malignant lymphoma forming a huge mass in the heart. An 82-year-old woman became aware of general fatigue and a cough in August 1999. Her right supraclavicular, bilateral axillary, and right inguinal lymph nodes were swollen. A hypodermical mass in the right frontal chest was detected. Her left axillary lymph node was biopsied. She was diagnosed as having non-Hodgkin lymphoma, diffuse large cell type, B-cell type. Computed tomography scans showed a markedly thickened right ventricular wall of the heart, swollen lymph nodes of the mediastinum, bilateral pleural effusions, and a tumor in the spleen. Lymphoma cells were found in the pleural effusion, and the lymphoma was diagnosed as clinical stage IV. Hypofunction of the heart, ejection fraction (EF) 49%, was demonstrated with transthoracic echocardiography. EF increased to 70% after 3 courses of chemotherapy with CHOP regimen. All lesions disappeared after 6 courses of chemotherapy were completed. After consolidative radiotherapy with a total dose of 37 Gy to the mediastinum and heart, bilateral pleural effusions, elevation of the patient's lactate dehydrogenase level and soluble IL-2 receptor value were recognized, which suggested relapse of the lymphoma, although histopathological confirmation could not be realized.

A 54-year-old woman with a 21-year history of sarcoidosis was admitted to our hospital with dyspnea on exertion, weight loss, and the appearance of consolidation in chest radiographs. The serum level of soluble IL-2 receptor was high, and CT findings demonstrated mediastinal, hilar and abdominal lymphadenopathy. The histological findings of subpleural consolidation in a transbronchial lung biopsy of the left lung showed giant cells; and those of a CT-assisted biopsy of a retroperitoneal lymph node revealed non-caseous epithelioid cell granulomas. After the biopsy, severe thrombocytopenia (6,000/microliter) developed. With prednisolone treatment, the platelet count rose to normal and the subpleural consolidation on chest radiography was improved. Five weeks later, the had a productive cough with fever, rapidly progressive cavitary lesions and consolidation on chest radiography. Aspergillus fumigatus was detected in the sputum by PCR, and Aspergillus antigen was detected in the serum. She died of progressive respiratory failure, in spite of therapy with amphotericin B and itraconazole. We report a rare case of sarcoidosis and idiopathic thrombocytopenic purpura accompanied with invasive pulmonary aspergillosis.

An 18-year-old woman with abdominal pain was diagnosed as having splenic cysts by computed tomography scan. She had high serum levels of CA19-9 (2886.8 U/mL; normal value, <35 U/mL), CA125 (131.1 U/mL; normal value, <35 U/mL) and soluble IL-2 receptor (1490 U/mL; normal range, 220-530 U/mL). The resected spleen weighed 1050 g, was 14 x 28 cm, and had more than 10 macroscopic cysts up to 10.3 x 9.5 cm. There were numerous microscopic cysts in the spleen and several on the splenic capsule. The levels of CA19-9 and CA125 in the cyst fluid were 2165550 U/mL and 160400 U/mL, respectively. After the surgery, the serum levels of the tumor markers decreased gradually. The inside of the largest cyst was mainly covered by granulation tissue with a focal lining of epithelial cells, and the other macroscopic cysts had stratified squamous epithelium. The microscopic splenic cysts and cysts on the splenic capsule were lined by either attenuated single-layered or multilayered epithelial cells. The lining epithelial cells of these cysts were positive for epithelial membrane antigen and cytokeratins. CA19-9 and CA125 were detected in the lining cells of the splenic cysts. In the present case, it is suspected that the splenic cysts were derived from the capsular lining cells that showed migration from the capsule or formed microcysts on the splenic capsule, as in the case of ovarian inclusion cysts.

A 24-year-old woman was referred to our hospital with fever and cervical lymphadenopathy. On admission, her serum concentration of soluble IL-2 receptor had increased to 1,740 IU/ml, LDH was 2,889 IU/l, and ferritin was 2,389 ng/ml. Dyspnea became evident (PaO2 60 Torr) with a further increase of serum ferritin to 96,552 mg/ml on day 11. Chest CT findings showed the thickening of the interlobular septa, bilateral pleural effusion, and swelling of mediastinal lymph nodes, symptoms which were very similar to those associated with lymphangitis carcinomatosis. She received steroid pulse therapy (methylprednisolone, 1,000 mg/day for three days). This resulted in a rapid improvement of her dyspnea and disappearance of the lymphatic blockade-mediated pulmonary findings in two days. A cervical lymph node biopsy was performed on day 12, and revealed that she had subacute lymphadenitis (Kikuchi disease). This case suggests that acute respiratory failure should be considered in cases of Kikuchi disease when associated with a lymphatic blockade.

We report a 62-year-old woman with intravascular lymphomatosis (IVL) which presented as subacute encephalopathy. She was admitted to our hospital because of loss of consciousness in the middle of February, 2006. Laboratory tests indicated elevated serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and cerebrospinal fluid protein. Magnetic resonance imaging (MRI) of the brain revealed multiple infarct-like lesions mainly in the white matter. After admission, her consciousness was soon improved, but the inflammatory response did not disappear with any antibiotics or virucides. Her consciousness was not exacerbated, and she was discharged in the middle of March, although the reason for loss of consciousness remained unknown. After discharge she developed an abnormal behavior and mental deterioration, and therefore she was readmitted late in March. On second admission, her consciousness was drowsy. Neurological examinations revealed conjugate deviation of her eyes to the left, left hemiparesis, and generalized hyporeflexia. Laboratory tests showed more elevated CRP than that of the last time, and raised soluble IL-2 receptor (sIL-2R). The repeated MRI of the brain disclosed that initial lesions of the white matter progressively enlarged and increased in number. To make an appropriate diagnosis of the lesions on the brain MRI, the open brain biopsy was performed. Microscopic examination showed that many small vessels were occluded by lymphoma cells (B-lymphocytes) with hemorrhage, and IVL was diagnosed. She was treated with regimens of combined chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone). After chemotherapy her consciousness and left hemiparesis were gradually improved and the levels of CRP were normalized. The infarcts-like lesions detected on the brain MRI became reduced and decreased. IVL is a rare disease, and the prognosis is generally poor, with a rapidly fatal outcome, leading to a postmortem diagnosis. In the present report, we successfully treated the patient by rituximab in addition to standard CHOP therapy. Rituximab may play an important role in the treatment of IVL.

A 79-year-old woman was admitted to a nearby hospital for seven days due to low-grade fever, loss of appetite and general fatigue. She was diagnosed with normal condition and discharged. She was admitted to our hospital one week later with disturbed consciousness. Laboratory findings upon admission revealed anemia, elevated alanine amino transferase, elevated total birirubin and thrombocytopenia. Abdominal CT demonstrated multiple low intensity lesions in the liver. Enhanced brain CT revealed multiple lesions with increased signal intensity lesions in the white matter and cortex. The value of soluble IL-2 receptor antibody was 16,000U/ml. Intravascular lymphoma was suspected because of brain CT finding and IL-2 receptor antibody titer. Methylprednisolone pulse therapy was started considering her age and general condition, but she was died thirteen days after admission. Postmorten examination revealed widespread intravascular aggregation of malignant lymphoma cells in the liver, spleen, bone marrow, bladder, ovary and stomach indicating a diagnosis of an Asian variant of intravascular large B cell lymphoma (AIVL). Neurological abnormalities are not usually associated with AIVL, but this patient had rare AIVL presenting with initial progressive nonspecific neurological symptoms.
