1/557. Successfully treated central nervous system Burkitt's lymphoma with minimal extraneural disease in a child.

    Burkitt's lymphoma, the most common childhood non-Hodgkin's lymphoma, usually presents with abdominal tumors. central nervous system (CNS) involvement in Burkitt's lymphoma is mostly secondary to advanced systemic disease, rarely with brain parenchymal lesions, and was previously recalcitrant to treatment. We report an unusual case of CNS Burkitt's lymphoma with minimal extraneural disease. This 10-year-old immunocompetent boy presented with increased intracranial pressure and seizures and was found to have multifocal intracerebral lesions on brain imaging studies. cerebrospinal fluid studies confirmed the presence of Burkitt's lymphoma cells. Abdominal computed tomography showed bilateral nephromegaly with left intrarenal lesions that disappeared after three doses of intravenous dexamethasone. The patient was treated for 6.5 months according to the LMB 89 group C protocol of the French Pediatric Oncology Society. The response was brisk and complete. The patient has been disease free for more than 4 years, and is believed to be cured. ( info)

2/557. Burkitt-like lymphoma presenting as a periodontal disease in AIDS patients: a report of two cases.

    Burkitt-like lymphoma of the oral cavity is relatively uncommon in patients with acquired immunodeficiency syndrome (AIDS). The lesion usually appears as a solitary ulcerated mass with rapid onset. Some may present initially as gingival inflammation which delays final diagnosis and treatment. This report describes the presentations of multifocal intraoral Burkitt-like lymphoma in two Thai heterosexual men with AIDS. The clinical features and the radiographic findings in both cases mimicked a periodontal disease, showing extensive widening of the periodontal ligament space and loss of lamina dura in all segments of the molar teeth. The patients eventually died 5 and 14 months after they were diagnosed with hiv infection. ( info)

3/557. Burkitt's lymphoma presenting as lower lip paraesthesia in a 24 year old Nigerian. Case report.

    An unusual case of stage D Burkitt's lymphoma in a 24 year old Nigerian female undergraduate is reported. There was a four month history of left lower lip paraesthesia followed three months later by a slowly progressive 'pimple-sized' nodular mandibular swelling arising from the mental foramen region. A full-blown, rapidly developing abdominal mass manifested only three weeks after a biopsy of the mandibular swelling. Aspiration of the latter and a histologic report of the mandibular mass confirmed Burkitt's lymphoma. The patient responded very well to appropriate chemotherapy. Clinicians should not overlook insidious jaw swellings in any adult residing in the endemic zone of Burkitt's lymphoma, in view of the fact that successful therapy is dependent on early diagnosis. Mental nerve paraesthesia is very rarely seen in Burkitt's lymphoma. ( info)

4/557. The association of latent Epstein-Barr virus infection with hydroa vacciniforme.

    patients with hydroa vacciniforme (HV)-like eruptions and malignant potential have been reported from asia and mexico, and those patients frequently had an associated latent Epstein-Barr virus (EBV) infection. In order to elucidate the association of latent EBV infection with HV, we studied six children with typical manifestations of HV by detection of EBV genes and EBV-related RNAs in biopsy specimens from cutaneous lesions. Cutaneous lesions of all six children with typical HV contained EBV-encoded small nuclear rna (EBER) cells in 3-10% of the dermal infiltrates, whereas no Bam HI-H, l-fragment (BHLF) mRNA, or transcripts encoding EA-D antigen, were detected. No EBER cells were detected in other inflammatory or benign lymphoproliferative skin disorders tested. polymerase chain reaction amplification confirmed the presence of EBV dna sequences in five of six biopsy specimens from the patients. Latent EBV infection is associated with the development of cutaneous lesions of HV. ( info)

5/557. American Burkitt's lymphoma-hand-mirror variant. A detailed investigation of cytologic, ultrastructural, and immunologic features.

    Previous studies of patients with lymphoid malignancies have suggested a relationship between survival and the presence of more than 40% hard-mirror cells in the bone marrow. This report represents the first detailed study of a patient with American Burkitt's lymphoma with numerous hand-mirror cells in the bone marrow during the course of the disease. The Burkitt cells were atypical because of their hand-mirror configuration in the bone marrow, the presence of cytoplasmic glycogen, the finding of an IgG surface marker, and a strongly positive acid phosphatase staining reaction. The presence of increased numbers of hand-mirror forms in the bone marrow during the course of the patient's illness may have clinical significance, because they were replaced by non-hand-mirror Burkitt cells in the terminal phase. More reports and investigations of patients with large numbers of hand-mirror forms in the bone marrow are needed to elucidate the full significance of this unusual cellular phenomenon. ( info)

6/557. Acute renal failure due to obstruction in burkitt lymphoma.

    Acute renal failure in burkitt lymphoma is commonly the result of tumor lysis syndrome. We present a 15-year-old boy who developed hypertension, seizures, and acute renal failure due to extrinsic compression of the bladder and ureters by a large retrovesical burkitt lymphoma. The causes of acute renal failure in burkitt lymphoma and the incidence of acute urinary obstruction in this disease are reviewed. ( info)

7/557. Burkitt's lymphoma of the ovary in association with pregnancy. Two case reports.

    Burkitt's lymphoma of the ovary, occurring in association with pregnancy, is rare, only one case having been previously reported. Two cases are reported here and the possible effect of pregnancy discussed. ( info)

8/557. Epstein-Barr virus-associated lymphoproliferative skin lesion with recurrent necrotic papulovesicles of the face.

    A 24-year-old man showed recurrent necrotic papulovesicles of the face. The cutaneous lesions started with erythema, followed by vesicles, necrosis, and crusting, and leaving depressed scars. light avoidance did not prevent the development of the lesions. Histologic examination revealed lymphoproliferative lesions confined to the skin. Latent Epstein-Barr virus (EBV) infection was detected in the lymphoid cells from the skin lesions by in situ hybridization. A moderate to high dosage of corticosteroids suppressed the development of new skin lesions, but relapses occurred when these systemic corticosteroids were tapered. ( info)

9/557. Inheritance of chromosomally integrated human herpesvirus 6 dna.

    Human herpesvirus 6 (HHV-6) genome has been detected in several human lymphoproliferative disorders with no signs of active viral infection, and found to be integrated into chromosomes in some cases. We previously reported a woman with HHV-6-infected Burkitt's lymphoma. fluorescence in situ hybridization showed that the viral genome was integrated into the long arm of chromosome 22 (22q13). The patient's asymptomatic husband also carried HHV-6 dna integrated at chromosome locus 1q44. To assess the possibility of chromosomal transmission of HHV-6 dna, we looked for HHV-6 dna in the peripheral blood of their daughter. She had HHV-6 dna on both chromosomes 22q13 and 1q44, identical to the site of viral integration of her mother and father, respectively. The findings suggested that her viral genomes were inherited chromosomally from both parents. The 3 family members were all seropositive for HHV-6, but showed no serological signs of active infection. To confirm the presence of HHV-6 dna sequences, we performed polymerase chain reaction (PCR) with 7 distinct primer pairs that target different regions of HHV-6. The viral sequences were consistently detected by single-step PCR in all 3 family members. We propose a novel latent form for HHV-6, in which integrated viral genome can be chromosomally transmitted. The possible role of the chromosomally integrated HHV-6 in the pathogenesis of lymphoproliferative diseases remains to be explained. ( info)

10/557. Acral erythema in children receiving high-dose methotrexate.

    Scant information is available concerning the occurrence and evolution of chemotherapy-induced acral erythema in children receiving intravenous high-dose methotrexate (MTX). Among 50 children with acute lymphoblastic leukemia or lymphoblastic lymphoma receiving a total of 203 courses of high-dose MTX (3-8 g/m2), 3 cases of acral erythema were observed. Painful erythema of finger and toe pads was noted in three children 3 days to 2 weeks after MTX infusion. The lesions resolved completely after blister formation and desquamation. These patients subsequently received high-dose MTX therapy without cutaneous problems. The present work points out that the chemotherapeutic schedule need not be modified in selected patients who develop acral erythema following high-dose MTX infusion. ( info)
