Mucormycosis occurs primarily in patients with severe underlying illness, especially leukemia, lymphoma, and uncontrolled diabetes mellitus. Cutaneous mucormycosis is somewhat less frequently associated with systemic illness than other forms of mucormycosis. The associated mortality is significantly less than that related to rhinocerebral form. More recent reports have shown that primary cutaneous mucormycosis has emerged as an important form of the disease. It develops where a break in the integrity of the skin has occurred as a result of surgery, bum, or other forms of trauma. We report a case of primary cutaneous mucormycosis in a healthy person without systemic illness, which was successfully treated with amphotericin B therapy for 2 weeks.

Nasal type natural killer (NK)/T-cell lymphoma is rare but clinically aggressive, with a high rate of mortality. It is characterized by the expression of the NK-cell antigen CD56, frequent extranodal spreading and a strong association with the Epstein Barr virus. It commonly appears as deep nodules, or an infiltrative or ulcerative plaque. We report a case of nasal type NK/T-cell lymphoma, clinically showing subcutaneous panniculitis. It recurred after complete response to chemotherapy.

The spleen is one of the largest organ in the reticuloendothelial system and plays an important role in theac-tivation of immune response. It is the organ most commonly injured after blunt abdominal trauma, and malig-nantlesions such as lymphoma, or these due to metastasis, occur not infrequently. Even so, it is ignored even inabdominal ultrasonography. Some benign splenic lesions, however can cause severe symptoms and result in high mortality, and their accurate diagnosis is therefore essential. This study describes the imaging findings andhistopathologic features of various nontraumatic benign splenic lesions.

BACKGROUND: The molecular mechanisms that are responsible for the initiation and progression of diffuse large B-cell lymphoma are largely unknown. p16 is an inhibitor of cyclin-dependent kinase and its inactivation by methylation has been reported as a major tumorigenic mechanism in malignant tumors. The aim of this study was to analyze the correlation between the clinical data and the p16 protein expression in diffuse large B-cell lymphomas. METHODS: Tumor samples were obtained from 62 patients who were suffering with diffuse large B-cell lymphoma. To investigate the role of p16 in the pathogenesis and progression of diffuse large B-cell lymphoma, 62 cases of diffuse large B-cell lymphoma were examined for their expression of p16 via performing immunohistochemistry. The correlation of the p16 expression with the various clinicopathologic findings was also analyzed. RESULTS: p16 was expressed in all the cases of reactive lymphoid hyperplasia (100%) and in 40 cases (64.5%) out of the 62 cases of diffuse large B-cell lymphoma that we studied. The expression rate of p16 was 31.8% in the high risk group and 82.5% in the low risk group of diffuse large B-cell lymphoma. The expression rate of p16 in the fatal cases was 12.5%. For our results, the loss of a p16 expression in diffuse large B-cell lymphoma was noted, and especially in the high risk group (P=0.04). CONCLUSION: The loss of p16 appeared to be involved in the genesis or progression of diffuse large B-cell lymphoma. In addition, the loss of the p16 expression may play important roles for patients' progression into the high risk group and it may cause more mortality for those patients with diffuse large B-cell lymphoma. Deranged expressions and loss of the p16 expression may play an important role in the pathogenesis of diffuse large B-cell lymphoma.

Chylous effusion is an unusual complication of malignant neoplasm, usually lymphoma. In cases with cancer, the tumor was usually extensive, and the prognosis was invariably poor with a one year mortality rate of 80%. It was also reported that chylous effusion could also result from liver cirrhosis. The incidence of this complication was reported to be 0.5% in patients with liver cirrhosis and ascites. Here we report a case of 62 year old male with chronic alcoholism history who presented with abdom-inal distension and right cervical mass. He was subsequently diagnosed as non-Hodgkin's lymphoma and chylous ascites with liver cirrhosis and treated with chemotherapy. In spite of treatment, lymphoma progressed and the patient expired.

Intestinal T-cell lymphomas are fairly uncommon, and can sometimes be associated with enteropathy. Enteropathy-associated T-cell lymphoma (EATL) is commonly accompanied by a nonspecific mucosal ulceration, similar to that observed as a complication of celiac disease. The clinical course of EATL is quite unfavorable, and tends to have a generally poor prognosis. When a tumor invades the bowel wall and is treated with corticosteroids and chemotherapy, cell lysis with perforation often occurs, particularly in case of lymphoma. Recent data indicate that extensive resection may improve local control, and eliminate the risk of early mortality due to visceral perforation or hemorrhaging in unresected lesions during chemotherapy. Here, we report the case of a 51-year-old male who was diagnosed with primary gastrointestinal lymphoma after colonoscopy, and presented with EATL after emergent exploratory laparatomy. We also include a review of the literature regarding this uncommon entity.

Primary low-grade lymphoma of the mucosa-associated lymphoid tissue (MALT) type lymphoma of the bladder is rare. A relationship between MALT lymphoma of the urinary bladder and chronic cystitis has been proposed by some reports. Additionally a relationship between MALT lymphoma of the urinary bladder and Helicobacter pylori has been reported. Here we present a case of regression of urinary bladder MALT lymphoma after antibiotic therapy, using H. pylori eradication protocol in an elderly patient, who had a high risk of treatment related mortality in curative systemic chemotherapy. The patient is a 74-year-old woman who had a history of chronic cystitis. She was diagnosed with stage IIA primary MALT lymphoma of the urinary bladder and was treated with H. pylori eradication triple therapy for 2 weeks. After 2 months, there was a marked regression of the bladder MALT lymphoma lesion in a computed tomography scan of the abdomen.

BACKGROUND AND OBJECTIVES: Polymorphic reticulosis (PMR), a type of lethal midline granuloma, has characteristics of necrosis, angiocentricity, and angiogenesis, which is also known as nasal T-cell lymphoma. In this study, we classified PMR and nasal lymphoma using immunohistochemical staining and investigated the clinical characteristics of nasal malignant lymphoma including survival rates with treatment modalities. MATERIALS AND METHODS: Twenty-six patients previously diagnosed with PMR or nasal lymphoma from May 1992 to April 1997 were included in this study. We performed immunohistochemical staining with CD3, CD56 and CD79a for classification and reviewed the patients' clinical characteristics and survival rates, retrospectively. RESULTS: Of twenty-six patients, twenty-five patients were classified as having angiocentric lymphoma and only one patient with B-cell lymphoma. Higher mortality rates were observed in patients receiving chemotherapy alone than in those receiving chemotherapy and radiation therapy and in advanced stage. CONCLUSIONS: Early detection and combined treatment could improve the survival rate of patients with nasal malignant lymphomas.

OBJECTIVETo study the clinical and pathological features of primary lymphoma of the testis and try to find out the rational treatment modality.

METHODSRetrospective and follow-up analysis was conducted in 23 patients with primary lymphoma of the testis. Survival analysis was performed by Kaplan-Meier process.

RESULTSThe primary clinical symptom was painless tumefaction. 78.3% lesions were Stage I(E) on diagnosis. Most of them were intermediate grade B cell lymphoma. All patients received orchiectomy followed by chemotherapy and some followed by radiotherapy. The median survival time was 42 months. The overall survival rates at 1, 3 and 5 years were 100.0%, 59.8% and 36.5%, respectively. The disease-free survival rates at 1, 3 and 5 years were 66.7%, 42.3% and 36.3%, respectively.

CONCLUSIONPrimary lymphoma of the testis is preferably treated by multi-modality treatment. More than 6 cycles of chemotherapy is rational after orchiectomy. Regional radiotherapy tends to reduce the local relapse.
