Diabetes insipidus, Sheehan''s syndrome and pregnancy

We diagnosed a case of primary cardiac lymphoma using transthoracic needle biopsy. A 70-year-old man was admitted because of dyspnea. Magnetic resonance imaging revealed a tumor mass in the right ventricular free wall. We performed ultrasound guided transthoracic needle biopsy using an 18-G needle, and diagnosed as malignant lymphoma by the biopsy specimen. This method may be useful for the diagnosis of cardiac lymphoma.     

Primary malignant lymphoma of the duodenum: report of a case

We present a case of long-term survival in primary malignant lymphoma of the duodenum treated with a curative surgical resection and post-operative chemotherapy. A 72 year-old man was admitted to our hospital complaining of epigastric discomfort. Endoscopy revealed an ulcerative tumor in the duodenal bulb. The tumor was diagnosed histologically as malignant lymphoma by endoscopic biopsy. A distal gastrectomy and duodenal bulb resection were performed with lymph nodes dissection. The tumor was histologically classified as B-cell phenotype, large cell, immunoblastic lymphoma of high grade, according to the Working Formulation. The patient received CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) chemotherapy after the operation, and he has no sign of recurrence during a follow-up period of 6 years.     

A case of malignant lymphoma with a metastasis to the lateral rectus muscle

We reported a 75-year-old woman with malignant lymphoma who had a metastasis to the right lateral rectus muscle. She was well until two months earlier, when a tumor in the left thigh began to enlarge. Ten days before admission, she noticed medial deviation of the right eyeball. Neurological examination showed the right esotropia with isolated paralysis of the right lateral gaze. She denied double vision. MR imaging demonstrated a swelling of the right lateral rectus muscle. Gallium scanning revealed abnormal accumulation in the right orbit and the left thigh. The tumor in the left thigh was histologically diagnosed as non-Hodgkin's lymphoma, diffuse large cell type. Discrete extraocular muscle metastasis is rare and unreported for malignant lymphoma. Reported cases of breast and thyroid cancers metastatic to the extraocular muscles did not develop diplopia similar to our case. The rapid growth of metastases to the extraocular muscles produces a large visual axes deviation, therefore no diplopia may be elicited.     

Six-year survival after excision of cardiac malignant lymphoma

We report a patient with a postoperative survival period of 6 years after the surgical excision of a cardiac malignant lymphoma. A 35-year-old woman underwent total excision of the tumor arising from the left ventricular outflow tract. After the operation, she was treated with chemotherapy for 6 months. She has been doing well thereafter without any medication. To date there is no evidence of recurrence.     

Primary non-Hodgkin malignant lymphoma of the male breast

A case of primary non-Hodgkin lymphoma of the male breast is reported. The patient was a 76-year-old Japanese with a history of bilateral gynecomastia. After the patient had received sex hormone treatment for the gynecomastia, rapid growth of a tumor in the right breast was noted, with regression of a contralateral breast lesion. Clinically, inflammatory breast cancer was suspected, and right mastectomy with ipsilateral axillary lymph node dissection was performed after intraarterial infusion chemotherapy using a cis-platinum derivative. The histology of the surgical specimen was non-Hodgkin malignant lymphoma of the diffuse large cell type, with focal tumor necrosis. Immunohistochemically, the tumor cells showed a B-cell nature. The patient is currently well without disease 39 months after surgery.     

Effect of rodents on reforestation in the moumtain regions near Beijing

A long survival is rarely observed in patients demonstrating recurrent malignant lymphoma with bulky disease because of the appearance of chemoresistant tumor cells after extensive chemotherapy, and moreover the presence of bulky disease has also been consistently associated with a poorer response rate and a shortened survival, due to the fact that tumor size is the most significant factor for the treatment of non-Hodgkin's lymphoma. We herein describe a case of a 53-year-old woman presenting with the chief complaint of abdominal fullness, who underwent intraoperative radiation therapy (IORT) for recurrent bulky non-Hodgkin's lymphoma in the mesenterium. The patient has had no evidence of tumor recurrence, based on the findings of regular abdominal computed tomographic scans, 60 months after initial chemotherapy and 28 months after IORT.     

Radical resection of primary malignant melanoma of the gallbladder with multiple metastases: report of a case

We present herein an usual case of primary malignant melanoma of the gallbladder in a 51-year-old man in whom an exploratory laparotomy for melena revealed six malignant melanoma lesions located in the gallbladder, main pancreatic duct, stomach, duodenum, jejunum, and a mesenteric lymph node. Total pancreatectomy was performed and histologically, junctional activity was seen only in the gallbladder, suggesting that this was the primary site. No melanotic lesions were found on the skin or eyes. The metastases to the main pancreatic duct and gastrointestinal tract appeared likely to have occurred as a consequence of the mucosal dissemination of the tumor cells shed into the bile. The post-operative course was uneventful and combined chemotherapy was administered for 16 months. No new metastatic lesions were found until 21 months postoperatively, when metastases were detected in the brain and thoracic spinal cord. These metastatic tumors were removed surgically, but the patient died from cerebral disturbance 26 months after the initial operation. Thus, we consider that aggressive surgical therapy was effective for extending the survival time and improving the quality of life of this patient.     

A surgical case of cardiac malignant lymphoma in right atrium

We reported a case of malignant lymphoma originating from the right atrium. The patient was a 71-year-old man who had no symptoms associated with heart failure and arrhythmias. At the time of admission the patient was suggested the presence of a tumor in the right atrium by an echocardiogram accidentally. Coronary angiography revealed a feeding artery to a tumor. Although cytological confirmation was not obtained, diagnostic extirpation of tumor was performed under cardiopulmonary bypass. The histological diagnosis was malignant lymphoma of B-cell origin. His postoperative course was uneventful and no recurrence had been observed one year postoperatively without chemotherapy.     

A case of primary cardiac hemangiosarcoma

A case of primary hemangiosarcoma of right atrium was reported. The patient was 43 years old female. She had the symptoms of tamponade due to massive bloody pericardial effusion. Echocardiography, computed tomography, NMR imaging and angiography revealed the precise delineation and extension of tumor, and also allowed diagnosis of hemangiosarcoma. Extirpation of tumor was performed under the cardiopulmonary bypass. The patient was died 3 months later after the operation for liver metastasis. The bloody pericardial effusion seems to be an important symptom of the primary malignant cardiac tumor, and early and precise diagnosis may allow successful operation and long survival of the patients.     

A case of renal pelvic cancer with recurrence of liver metastasis showing partial response by injection of methotrexate and intraarterial infusion of cisplatin and pirarubicin

The patient was a 71-year-old man who had been diagnosed as having a left renal pelvic cancer with liver metastasis. We performed total left nephroureterectomy with lymphnode cleaning and partial resection of the liver. Because abdominal CT 5 months after the operation revealed multiple metastasis of the liver, we performed chemotherapy with a regimen consisting of methotrexate 50 mg (intravenous injection), cisplatin 30 mg and pirarubicin 20 mg (intraarterial infusion), and leucovorin 3 mg (intramuscular injection), three times at intervals of 6 hours. Ten days after chemotherapy, CT revealed the disappearance of most of the liver metastatic lesions, and a partial response was obtained. We are now performing the regimen at an interval of a month to a month and one-half to control the metastatic lesions.     

A case of surgical resection for metachronous multiple liver metastases of chromophobe cell renal carcinoma

A 64-year-old female was hospitalized because of multiple liver metastasis, during the postoperative observation of chromophobe cell renal carcinoma. Injection of Epirubicin/Lipodol into the right hepatic artery followed by transcatheter arterial embolization was performed two times, and the metastatic foci responded favorably to this therapy. Since no new metastatic tumors were observed in the liver nor any other organs, a partial hepatectomy was thus performed. The liver tumor was pathologically diagnosed to be metastasis of the chromophobe cell renal carcinoma. The postoperative course has been uneventful and at present, 6 months after the operation, no further tumors have been observed.     

Iontophoresis: an alternative in the treatment of dental caries?

Celiac sprue (CS) is frequently complicated by malignancy, most commonly small intestinal lymphoma. Our study was performed in an area with a high prevalence of CS to define the clinical features, response to treatment, and outcome of this tumor. Of a total of 31 lymphomas complicating CS identified, 30 case records and 24 tumor specimens were reviewed. Overall 1-year survival was 9 of 29 (31%) and 5-year survival 3 of 27 (11%). Seven previously diagnosed celiac patients developed lymphoma; length on gluten-free diet ranged from 12 to 252 months (median 44 months). In this group, presentation was nonspecific, diagnosis difficult, and survival poor (lymphoma diagnosed in life in four of seven, mean survival 2.25 months). Twenty-three patients had CS and lymphoma diagnosed during the same illness. In this group, 14 of 23 presented with a surgical emergency and were treated with tumor resection and chemotherapy. Nine are disease-free and alive or died of another cause after 10-196 months (mean 74 follow-up). Celiac-associated lymphoma is a frequent, difficult to diagnose, and commonly fatal complication of CS. An aggressive diagnostic approach, including laparoscopy, is recommended. Long-term survival can be expected in a significant number of these patients and in our series was almost exclusively confined to those treated with chemotherapy.     

Cardiac malignant pheochromocytoma with bone metastases

A patient with malignant cardiac pheochromocytoma with bone metastases is described. The primary tumor was located between the pulmonary trunk and the left atrium, while metastatic lesions were found in the iliac bones. Treatments with antihypertensive agents, alpha-methylparatyrosine, and combination chemotherapy with cyclophosphamide, vincristine, and dacarbazine partially improved the patient's symptoms, catecholamine levels, and the metastatic lesion of the iliac bones. However, the primary tumor in the heart progressively increased in size and the patient died of disseminated intravascular coagulation and other various complications about 4 years after the diagnosis of the disease.     

A case of T-cell malignant lymphoma developing in the chest wall of chronic pyothorax after artificial pneumothorax

A 66-year-old man, with a past history of artificial pneumothorax for pulmonary tuberculosis at the age of 17, was admitted to our hospital because of progressive left precordial pain and left anterior chest wall tumor. Because of chronic pyothorax complicated by a tumor suggested by imaging diagnosis, surgery was performed for the purpose of fenestration. A diagnosis of diffuse large cell T-cell malignant lymphoma was made by the biopsy taken at surgery. Postoperatively the patient received 6 courses of combination chemotherapy with CHOP, the course turned favorable. The left precordial pain and tumor disappeared. The patient is doing well at 11 months postoperatively. Recently, cases of malignant lymphoma developing in the chest wall of chronic pyothorax have been increased and the majority of cases of the malignant lymphoma is B-cell type. T-cell type is rare. Follow-up of chronic pyothorax's patients necessarily are attentioned on the developing of the malignant lymphoma.     

Functional activity of Rh monoclonal antibodies in ADCC assay

A 58-year-old woman with malignant mesothelioma metastatic to the orbit is reported. Malignant pleural mesothelioma was diagnosed by pleural biopsy. Marked reduction of pleural effusion was obtained with intrapleural interleukin-2 therapy. Systemic chemotherapy failed to elicit a response after the first recurrence of the tumor. Multiple systemic metastasis, including metastasis to the orbit, developed and the patient died one year and 4 months after the initial diagnosis. Although malignant mesothelioma is known to spread hematogenously, sometimes producing brain metastasis, there have been few reports of orbital metastasis, and in fact the present report may be the first clinically documented account of its kind.     

Molecular biologic markers and cancer risk assessment

BACKGROUND: Malignant melanoma is the second most common vulvar malignancy. The superficial inguinal lymph nodes are the main site of metastases. Endometrial metastasis of vulvar malignant melanoma has not been previously reported. CASE: Vulvar malignant melanoma was diagnosed in a 60-year-old, postmenopausal woman. Immunohistochemical stains were positive for vimentin and S-100 protein and negative for HMB-45. Six months following vulvectomy, right inguinal lymphadenectomy and immunotherapy, curettage was performed due to postmenopausal bleeding. Histologic and immunohistochemical examinations revealed metastatic malignant melanoma with the same staining reactivity as the primary vulvar neoplasm had. Hysterectomy and bilateral salpingo-oophorectomy was performed, disclosing invasion of the endometrium and the inner two thirds of the myometrium. CONCLUSION: Only 10 other cases of endometrial metastases from malignant melanoma have been previously reported. All those cases involved a primary tumor occurring in the trunk and extremities. This is presumably the first report on endometrial and myometrial metastases from vulvar malignant melanoma.     

Cystic tuberculosis of the bone mimicking osteogenic sarcoma

Cardiac infiltration by lymphoma is a rare finding during life. However, metastatic deposits are frequently found at postmortem in patients with malignant lymphoma. In the past, this may have been due to difficulties in imaging the heart. Today, 2-dimensional echocardiography is a widely used, safe, noninvasive test which allows excellent spatial imaging of cardiac structures. We report a case of extensive primary myocardial and pericardial involvement by malignant lymphoma in which echocardiography was used to document the diagnosis and follow the response to chemotherapy.     

Successful preoperative interferon-alpha therapy of renal cell carcinoma with tumor thrombus extending into the inferior vena cava--case report

We report a case of renal cell carcinoma in whom preoperative interferon-alpha therapy was successful in reducing the primary lesion and the tumor thrombus extending into the inferior vena cava. A 67-year-old man was referred to our hospital because of his right renal mass. We made a diagnosis of a right renal tumor with tumor thrombus by imaging examinations. Because his performance status was 3, a radical operation was considered risky. So we started interferon-alpha therapy. Four months after the start of interferon-alpha therapy, the primary lesion and the tumor thrombus reduced in their size, and the clinical response was evaluated as partial response by the response criteria for urological cancer treatment. Because of improving the performance status and reducing the tumor size, radical nephrectomy and tumor thrombectomy could be performed. Pathological examinations revealed that viable renal cell carcinomas were found only in some small parts of the primary lesion, but not in the tumor thrombus. Postoperatively, no recurrence and metastasis of renal cell carcinoma of the patient have been detected in these two and a half years.     

Disaster-related psychiatric care system in the United States

We report herein the case of a 57-year-old man in whom malignant lymphoma originating in the gastric remnant was confirmed 25 years after a subtotal gastrectomy with Billroth II reconstruction had been performed for gastric ptosis. Gastroscopy revealed an ulcerated tumor on the fornix, and histologic examination of the endoscopic biopsy specimens demonstrated malignant lymphoma. Thus, total gastrectomy with splenectomy, pancreatectomy, and resection of the previously anastomosed jejunal stoma were performed. Histologic examination of the stomach remnant confirmed a diagnosis of B-cell lymphoma of the large-cell type. Although we were unable to study the surgical specimen from the initial operation, the possible relationship between pseudolymphoma and malignant lymphoma has been presented in the literature, which is reviewed following this case report.     

Metastatic renal tumor of malignant salignant salivary-gland-like tumor of the lung: A case report

A 17-year-old woman was admitted to our hospital for the investigation of asymptomatic gross hematuria. Twenty nine months ago, she had received the right lower lobectomy because of the malignant salivary gland type mixed tumor of the bronchus. The intravenous pyelography and the right retrograde pyelography showed the irregular wall of the right renal pelvis. The computerized tomography showed a hypodense tumor which occupied the lower half of the right kidney. Cystoscopy showed bleeding from the right ureteral orifice. Chest X-ray revealed multiple lung metastases at the first examination, but right nephrectomy was performed because gross hematuria continued. The tumor thrombus, which spreaded into vena cava, was removed. The pathological diagnosis was the metastatic renal tumor of malignant salivary gland type mixed tumor. The patient died 102 days postoperatively.
