Multicentric Castleman disease (MCD) is a lymphoproliferative disorder associated with human herpesvirus 8 (HHV-8) infection among persons with human immunodeficiency virus (HIV) infection. Treatment often includes chemotherapy, and progression to non-Hodgkin lymphoma frequently occurs. MCD is characterized in part by active HHV-8 replication, and many of the symptoms of MCD may be attributable to viral gene products. We describe the effect of ganciclovir on the clinical and virologic course of MCD in a series of 3 case reports. Two patients experienced a reduction in the frequency of episodic flares of MCD and detectable HHV-8 DNA with intravenous or oral ganciclovir, whereas the third patient recovered from an acute episode of renal and respiratory failure with intravenous ganciclovir therapy. These data provide in vivo evidence for the utility of antiviral agents against HHV-8 in the management of MCD.

The beneficial role of corticosteroid therapy for the treatment of methotrexate-induced pneumonia remains controversial. We report two cases of acute severe interstitial pneumonia induced by methotrexate in patients with non-Hodgkin lymphoma given a polychemotherapy protocol (M'BACOD). The first signs appeared on the eleventh day of the first cycle in patient one and on the tenth day of the third cycle in patient two. The causal implication of methotrexate was based on the history, the clinical and radiological presentation, and the negative tests in both patients: lymphocyte alveolitis with granulomatous lesions on the transbronchial biopsy in patient one and positive leukocyte migration test in the presence of methotrexate in patient two. Early acute respiratory failure required high flow rate oxygen therapy with positive expiratory pressure ventilatory assistance. The course was rapidly favorable both for blood gases and radiographic presentation without corticosteroids. These two cases illustrate that pulmonary disease can be cured without corticosteroids despite severe respiratory failure at onset. This provides a further argument on reservations about using corticosteroids for suspected methotrexate-induced pneumonia.

Microsporidia are ubiquitous obligate eukaryotic intracellular parasites that are now felt to be more akin to degenerate fungi than to protozoa. Microsporidia can be highly pathogenic, causing a broad range of symptoms in humans, especially individuals who are immunocompromised. The vast majority of human cases of microsporidiosis have been reported during the past 20 years, in patients with HIV/AIDS, while only relatively rare cases have been described in immunocompetent individuals. However, microsporidia infections are being increasingly reported in patients following solid-organ transplanation, where the main symptom has been diarrhea. The authors report the first case of pulmonary microsporidial infection in an allogeneic bone marrow transplant recipient in the United States and only the second case in the world. The patient, with a history of Hodgkin disease followed by acute myelogenous leukemia received a T-cell-depleted graft, but succumbed to respiratory failure 63 days post transplantation. An open lung biopsy, taken just before death, was originally thought to show toxoplasmosis. The correct diagnosis of microsporidiosis was made postmortem by light and electron microscopy. DNA polymerase chain reaction analysis confirmed the diagnosis and furthermore revealed it to be the dog strain of the microsporidia species Encephalitozoon cuniculi. Although to date rarely diagnosed, microsporidial infection should also be considered in the differential diagnosis of, e.g., unexplained pulmonary infection in bone marrow transplant patients.

Disseminated strongyloidiasis is a rare manifestation in patients on immunosuppressive drugs. We report two cases of fatal disseminated Strongyloides stercoralis infestation. The first was in a patient of pemphigus vulgaris who developed an exacerbation of symptoms, one year after diagnosis and was given intravenous dexamethasone and azathioprine and in the third week of hospitalization developed features of septicemia, respiratory failure and petechial hemorrhages which were proven to be due to disseminated strongyloidiasis. The second patient was diagnosed to have stage IV diffuse large cell type of non-Hodgkin lymphoma and after the second cycle of chemotherapy, developed generalized symptoms of septicemia, respiratory failure, purpuric macules and patches. This was also proven to be disseminated strongyloidiasis.

We report an extremely rare case of interdigitating dendritic cell sarcoma/tumor (IDCS). A 52-year-old man presented with a 2-week history of fever in January 2002. Physical examination revealed enlarged, painless right axillary lymph nodes, and hepatosplenomegaly. Whole-body computerized tomography showed enlarged lymph nodes in mediastinal, right axillary, abdominal para-aortic, ileum, and inguinal regions. Hepatosplenomegaly was also detected. In addition to abnormal liver function tests, serum levels of soluble interleukin-2 receptor and ferritin were elevated. Excisional biopsy of right axillary lymph node was performed in February 2002. Histological examination showed a diffuse proliferation of medium-to large-sized cells with round or oval nuclei and abundant cytoplasm. Spindle shape cells and Hodgkin-like giant cells were also seen. Immunohistochemically, the tumor cells expressed S-100 protein, CD 68, and CD 45 RO. They were negative for CD 1, CD 3, CD 15, CD 20, CD 21, CD 23, FDC, DRC, and p80. These findings were compatible with the diagnosis of IDCS. The patient was treated with polychemotherapy consisting of doxorubicin,cyclophosphamide, vincristine, and prednisone. However, he developed fungal pneumonia and died of respiratory failure 1 month after the start of treatment.

Paraneoplastic pemphigus (PNP), also called paraneoplastic autoimmune multiorgan syndrome, is a rare disorder associated with underlying neoplasia. The common underlying neoplasms include non-Hodgkins lymphoma, chronic lymphocytic leukemia, and Castlemans disease. Though B-cell lymphoma is the most common underlying malignancy, only one case associated with splenic B-cell lymphoma has been recognized. The prognosis of PNP is very poor, and PNP-associated bronchiolitis obliterans (BO) is not uncommon. Herein, we report a 44-year-old woman who initially presented with multiple oral ulcers, conjunctivitis, and numerous cutaneous blisters. Serial workup established the diagnosis of PNP and revealed an underlying splenic B-cell lymphoma. Although the mucocutaneous lesions gradually healed after splenectomy and chemotherapy, deteriorating respiratory function developed 7 months later with pathologically proven BO. She finally succumbed to respiratory failure 12 months after presentation despite intensive respiratory care.

With Hodgkin lymphoma (HL), other (autoimmune) diseases may occasionally occur or associate, whereas as a late treatment-complication, second tumour may develop. In our patient HL was diagnosed in 1996 and consequently received COPP/ABV and mantle irradiation. Due to the residual mediastinal tumour CRu was declared but later on no progression/relapse could be proved by PET. In 2000 Graves's disease, in 2001 myasthenia gravis was diagnosed, which showed resistance for immunosuppressant drugs, thus plasmapheresis, intravenous immunoglobulin treatments were applied. In 2005, the residual mediastinal tumour started progressive growth, which leads to thoracotomy in which the tumour was removed, it was malignant peripheral nerve sheath tumour. The disease showed progression despite the chemotherapy applied and the patient died in 2007 due to respiratory failure. Not even the postmortem histopathologic examination revealed the relapse of HL. Association of Hodgkin lymphoma, and two antibody-mediated autoimmune diseases, Graves' disease and myasthenia gravis, is rare and has not yet been reported in the literature. The etiologic role of genetic predisposition and immune regulatory disorder must definitely be thought of, as the possibility of mere coincidence is extremely small. Malignant peripheral nerve sheath tumour is a rare complication of irradiation, which underlines the importance of the risk or/and response adapted therapy of HL.

A 58-year-old man was submitted to our intensive care ward with respiratory failure due to pneumonitis. He had previously been treated for non-Hodgkin lymphoma by autologous stem cell transplantation, as a result of which bone marrow function was reduced. Further analysis showed infection with new influenza A(H1N1); typing revealed an oseltamivir-resistant subpopulation (H275Y). The patient was treated with oseltamivir and intravenously with zanamivir, but died of respiratory disease progression. This is the first published case of oseltamivir-resistant new influenza A(H1N1) infection in the Netherlands.

Paraneoplastic pemphigus is an autoimmune blistering disease associated with an occult or previously diagnosed tumor. Its clinical, histological, and immunological features have been clearly defined. It is characterized by the presence of polymorphic skin lesions and by erosions of the oral and genital mucosas that are refractory to conventional treatments. The histology can be variable and includes acantholysis or lichenoid dermatitis. Circulating autoantibodies are a constant feature and confirm the diagnosis. We describe 2 girls with paraneoplastic pemphigus associated with Hodgkin lymphoma in one and Castelman disease in the other. Both children had oral and genital lesions that did not respond to conventional treatments. Biopsy revealed acantholysis in one and a lichenoid reaction in the other, and immunoassays confirmed the diagnosis. Chemotherapeutic treatment of the underlying disease was performed in both cases, together with high-dose corticosteroids for the skin and mucosal lesions. Both patients died due to respiratory failure. We suggest that paraneoplastic pemphigus, although rare in childhood and adolescence, should be included in the differential diagnosis of periorificial erosive dermatitis; this may assist in the detection of an occult neoplasm.

Radiotherapy may lead to late-onset, rare, but sometimes life-threatening complications that need to be recognized for timely management. We report the case of a 39-year-old man who presented with a 20-kg weight loss with severe dysphagia and respiratory failure. His medical history was noticeable for Hodgkin's lymphoma that was treated 20 y previously. The physical examination and electroneuromyography indicated vagal and phrenic neuropathies. We concluded that the patient had late-onset esophageal motor disorder and bilateral phrenic paralysis secondary to the radiotherapy received 20 y previously for the lymphoma. The patient's management included long-term nutritional support. Although late-onset vagal and phrenic nerve injuries have been described separately after radiotherapy, we report the first case of paralysis at both sites. Another striking feature of this observation is the subsequent severe malnutrition that accompanied these paralyses.
