1/257. Human herpes-virus 8 seropositive patient with skin and graft Kaposi's sarcoma after lung transplantation.

    Kaposi's sarcoma (KS) has been reported after solid organ transplantation mostly in recipients of renal, liver, heart, and bone allografts. We describe the first case of a patient with lung transplantation who developed KS of the skin, but also of the lung graft. The tumors were localized to places of previous trauma, implying the involvement of a Koebner phenomenon. Moreover, a polymerase chain reaction assay revealed the presence of dna sequences of herpesvirus 8 (HHV-8) on tissue of the cutaneous KS. Serological tests showed HHV-8 seronegativity of the graft donor and HHV-8 seropositivity of the patient before lung transplantation suggesting that the latter was already infected before the surgery and that immunosuppression resulted in the development of KS. This case report raises the question of the prevalence of HHV-8 in candidates for transplantation and organ donors, and of the value of an antiviral prophylaxis to lower the risk of KS.

2/257. Herpesvirus 8 inclusions in primary effusion lymphoma: report of a unique case with T-cell phenotype.

    We describe a case of primary effusion lymphoma with T-cell phenotype, mixed genotype, and intranuclear herpesvirus inclusions visible with the light microscope. Cells were studied by immunohistochemical analysis, in situ hybridization, immunoglobulin and T-cell receptor gene rearrangement, and polymerase chain reaction. Primary effusion lymphoma cells with T-cell phenotype revealed herpesvirus 8 inclusions predominantly seen in apoptotic cells, suggesting that productive viral infection is associated with cell death. Clinical features were typical of primary effusion lymphoma. Cytologic, molecular genetic, and phenotypic features demonstrated a unique variant of primary effusion lymphoma.

3/257. Human herpesvirus-6 and sudden death in infancy: report of a case and review of the literature.

    Investigation of sudden death in infancy is a vital function of the medical examiner's office. Surveillance of these cases may lead to recognition of new diseases or new manifestations of previously described diseases. Human herpesvirus-6 (HHV-6) is a relatively newly described virus that has been recognized as a cause of acute febrile illness in early childhood. While most cases are apparently self-limited, seven fatal cases have been reported. We present a case of a seven-month-old Latin American male with recent otitis media and vomiting who was found dead in bed. autopsy revealed interstitial pneumonitis with an atypical polymorphous lymphocytic infiltrate in the liver, kidney, heart, spleen, lymph nodes, and bone marrow, associated with erythrophagocytosis. polymerase chain reaction (PCR) analysis of formalin-fixed paraffin-embedded tissue was positive for HHV-6 and negative for Epstein-Barr virus (EBV) and cytomegalovirus (CMV). HHV-6 was also detected in the atypical lymphoid infiltrate by in-situ hybridization.

4/257. association of body cavity-based lymphoma and human herpesvirus 8 in an hiv-seronegative male. Report of a case with immunocytochemical and molecular studies.

    BACKGROUND: Recently lymphomas arising primarily in serosal surfaces have been found in patients with advanced acquired immunodeficiency syndrome (AIDS), but they very rarely seem to occur in human immunodeficiency virus (hiv)-negative patients. Studies on a subset of these lymphomas suggested that they represent a distinct entity associated with Kaposi's sarcoma-associated herpesvirus or human herpesvirus 8 (HHV-8). CASE: An 83-year-old, hiv-negative male was admitted to the hospital with a massive pleural effusion. Abdominal and chest computed tomographic scanning was normal. Cytologic analysis of the pleural effusion revealed a large cell, non-Hodgkin's lymphoma. polymerase chain reaction analyses on genomic dna from the pleural effusion demonstrated the presence of HHV-8 sequences in the absence of Epstein-Barr virus. CONCLUSION: It is possible and advantageous to diagnose body cavity-based lymphoma with a combination of cytologic, immunocytochemical and molecular studies of the pleural effusion in conjunction with clinical and radiographic information.

5/257. Neuroinvasion by human herpesvirus type 7 in a case of exanthem subitum with severe neurologic manifestations.

    A 19-month-old girl presented with severe neurologic symptoms associated with exanthem subitum. Human herpesvirus type 7 (HHV-7) dna was detected in the CSF and serum, and supported by serologic studies. The patient was diagnosed with encephalopathy due to an acute HHV-7 infection. Neuron-specific enolase in the CSF was strongly elevated during the acute stage of infection, suggesting that the encephalopathy was due to viral invasion of the brain.

6/257. Neonatal stridor in association with herpes simplex infection of the larynx.

    herpes simplex virus (HSV) infection in the neonatal period may be confined to the eyes, skin and upper aerodigestive tract or may be widely disseminated to other organs, with particular recognition of involvement of the central nervous system (CNS) causing herpes encephalitis (Whitley et al., 1980a, b; Andersen, 1987). Primary laryngeal HSV infection is extremely uncommon. We present a case of acute neonatal stridor secondary to such localized disease and discuss its management.

7/257. Post transplant CD8 gammadelta T-cell lymphoma associated with human herpes virus-6 infection.

    Gammadelta T-cell lymphoma is a rare T-cell lymphoproliferative disorder that has been reported in both immunocompetent and immunocompromised persons. This report describes a forty eight year old patient who developed gammadelta T-cell lymphoma four years after undergoing living-related kidney transplantation. The lymphoma expressed CD2, CD3, CD7, CD8 and CD56, and the gammadelta T-cell receptor and did not express CD5, CD4 and the alphabeta T-cell receptor. In addition, HHV-6 was cultured from the patient's bone marrow, marking the first time that this virus has been associated with gammadelta T-cell lymphoma. Since all patients with gammadelta T-cell lymphoma described to date have responded poorly to standard combination chemotherapies, the patient was treated with the purine analogue 2-chlorodeoxyadenosine. While he responded transiently to treatment, long term remission was not achieved indicating that additional therapeutic approches still need to be developed, for the management of this disorder.

8/257. Kaposi's sarcoma-associated herpesvirus infection in the lung in multicentric Castleman's disease.

    A 32-year-old female was admitted for evaluation of multiple infiltrates on a chest radiograph. A diagnosis of multicentric Castleman's disease was made on the basis of typical clinical manifestations. Transbronchial lung biopsy (TBLB) revealed histological findings reported in lymphocytic interstitial pneumonia. Both the polymerase chain reaction and in situ hybridization with a probe specific for Kaposi's sarcoma-associated herpesvirus (KSHV) sequences demonstrated the presence of KSHV in the TBLB sample.

9/257. Temporally-specific retrograde amnesia in two cases of discrete bilateral hippocampal pathology.

    The role of the hippocampus in retrograde amnesia remains controversial and poorly understood. Two cases are reported of discrete bilateral hippocampal damage, one of which was a rare case of limbic encephalitis secondary to the human herpes virus 6. Detailed memory testing showed marked anterograde memory impairment, but only mild, temporally-limited retrograde amnesia that covered a period of several years in both autobiographical and factual knowledge domains. The absence of extensive retrograde amnesia in these two cases points to a time-limited role for the hippocampus in the retrieval of retrograde memories, and suggests that entorhinal, perirhinal, parahippocampal, or neocortical areas of the temporal lobe may be more critical than the hippocampus proper for long-term retrograde memory functioning. Our findings offer general support to theories of memory consolidation that propose a gradual transfer of memory from hippocampal to neocortical dependency.

10/257. Sudden unexpected death associated with HHV-6 in an adolescent with tuberous sclerosis.

    A 14-year-old female with tuberous sclerosis and history of seizures was found dead in bed at home 3 days after she had been assessed as doing well at a routine neurology clinic appointment. She had been treated with an antiepileptic drug, felbamate, for 36 months and had been seizure-free except for one seizure episode 5 months before death. Postmortem examination revealed cerebral edema, with uncal and tonsillar herniation, and pulmonary edema, consistent with seizure-induced apnea. Multiple microglial nodules with mature perivascular lymphocytic cuffing and diffuse infiltrates were identified around subependymal tuberous sclerosis giant cell nodules. Immunostaining and electron microscopy revealed human herpesvirus-6-infected macrophages, astrocytes, lymphocytes, and endothelial cells in the subependymal tuberous sclerosis lesions and choroid plexus. Subacute human herpesvirus-6 encephalitis is postulated to have precipitated a seizure and thus sudden unexpected death in epilepsy in this otherwise stable adolescent patient.
