Abstract
ABSTRACT Immunodeficiency-associated lymphoproliferative disorders are associated with latent infection by Epstein-Barr virus (EBV). Most cases of EBV-positive immunodeficiency-associated lymphoproliferative disorders arise from B cells, although some are of T-cell or natural killer origin. Cutaneous involvement is unusual and sporadically reported in the literature. We describe a rare case of an EBV-positive T-cell lymphoma presenting in the skin of a 32-year-old woman using adalimumab for neurosarcoidosis.

Abstract
T-cell or natural killer (NK)-cell posttransplant lymphoproliferative disorder (T-PTLD) is a rare but severe complication after transplant. Here we present the clinicopathological features of a single-center series of nine cases. Additionally, we summarize the clinicopathological findings of 147 cases of T/NK-cell PTLD reported in the literature in an attempt to define subtype-specific characteristics. T/NK-cell PTLD occurs in patients of all ages, usually extranodally, and most frequently after kidney transplant. Organ specific incidence, however, is highest following heart transplant. Approximately one-third of T-cell PTLDs are Epstein-Barr virus (EBV)-related, with peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) being the most prevalent EBV-associated T-cell PTLD. A male predominance is observed, which is most striking in the EBV(+) group, particularly in PTCL, NOS. With a median posttransplant interval of 72 months, T-cell PTLDs are among the late-occurring PTLDs. Of the most common T-cell PTLDs, anaplastic large cell lymphoma (ALCL) has the best prognosis, whereas PTCL, NOS and hepatosplenic T-cell lymphoma (HSTCL) have the worst prognosis. EBV(+) cases seem to have a longer survival than EBV(-) cases, suggesting a different pathogenetic mechanism.

Abstract
A joint working group established by the Haemato-oncology subgroup of the British Committee for Standards in Haematology (BCSH) and the British Transplantation Society (BTS) has reviewed the available literature and made recommendations for the diagnosis and management of post-transplant lymphoproliferative disorder (PTLD) in adult recipients of solid organ transplants. This review details the risk factors predisposing to development, initial features and diagnosis. It is important that the risk of developing PTLD is considered when using post transplant immunosuppression and that the appropriate investigations are carried out when there are suspicions of the diagnosis. These must include tissue for histology and computed tomography scan to assess the extent of disease. These recommendations have been made primarily for adult patients, there have been some comments made with regard to paediatric practice.

Abstract
PURPOSE Bexarotene is a retinoic X receptor agonist that has been shown in vitro to inhibit growth and induce differentiation of myeloid leukemic cell lines. We therefore conducted a phase I dose escalation study to assess the maximum tolerated dose, toxicities, and activity of bexarotene in patients with non-M3 acute myeloid leukemia (AML). EXPERIMENTAL DESIGN We enrolled patients with active non-M3 AML who had either relapsed or refractory disease or were not eligible for standard cytotoxic chemotherapy. Cohorts of three to six patients received escalating doses of daily oral bexarotene ranging from 100 to 400 mg/m(2) until evidence of disease progression or unacceptable adverse events occurred. RESULTS Twenty-seven patients, with median age of 69 years (range, 51-82 years), were treated. Twenty-four (89%) patients had undergone prior chemotherapy. At the highest dose level tested (400 mg/m(2)), three of six patients had to reduce their dose of bexarotene due to grade 3 adverse events. The maximum tolerable dose of bexarotene was determined to be 300 mg/m(2). Clinical activity was manifested by 4 (15%) patients with reduction in bone marrow blasts to <or=5%, 11 (41%) patients with improved platelet counts, and 7 (26%) patients with improved neutrophil counts. Three patients with relapsed AML survived >1 year while taking bexarotene. Leukemic blast differentiation was suggested by the presence of the leukemic cytogenetic abnormality in mature circulating granulocytes and the occurrence of differentiation syndrome. CONCLUSIONS The recommended dose of bexarotene for future studies is 300 mg/m(2)/d. Bexarotene is well tolerated in patients with non-M3 AML and has evidence of antileukemic activity.

Abstract
Hepatosplenic T-cell lymphoma (HSTL) is an aggressive lymphoma. In post-transplant immunosuppressed patients, HSTL is usually rapidly fatal. We report successful treatment of post-transplant HSTL in a 50-year-old renal allograft recipient by reducing immunosuppression and using intensive chemotherapy consisting of alternating cycles of HyperCVAD (cyclophosphamide, vincristine, doxorubicin, and dexamethasone) and MTX/HiDAC (methotrexate, Ara-C). Remission is ongoing at 8+ years. Literature review identified another 20 cases of HSTL in solid organ transplant recipients: median survival was 4 months; no other patients survived beyond 12 months. Bone marrow involvement was universal, but changes were often subtle: 6 of 12 cases had nondiagnostic examinations earlier on. High index of suspicion may lead to more timely diagnosis of this uncommon form of post-transplant lymphoproliferative disorder, and treatment with intensive chemotherapy such as HyperCVAD may be curative.

Abstract
Atopic dermatitis is a chronic, highly pruritic, and frequently recurring inflammatory skin disease that can be burdensome to affected individuals as well as to their family members, the health care system, and society as a whole. Immunomodulatory agents, such as topical corticosteroids and topical calcineurin inhibitors (TCIs), target the underlying immunopathology of atopic dermatitis and are the foundation of pharmacologic treatment for disease exacerbations. Recent recommendations from the United States Food and Drug Administration prompted the addition of a black-box warning and medication guide for tacrolimus ointment and pimecrolimus cream (both TCIs). The recommendations were based on a theoretical risk of malignancy derived from safety profiles, animal data, and reported cases of malignancy from clinical trials and postmarketing safety surveillance of oral calcineurin inhibitors. We know of no data that suggest that TCI use increases the risk of malignancy. Several dermatologic associations have issued statements supporting the safety of TCIs, and independent oncology experts have concluded that reported lymphomas were not related to TCI use. The black-box warning added to the TCI prescribing information also states that no causal link has been established. Effective treatment of atopic dermatitis can help alleviate the burden this disease imposes, and TCIs remain important treatment options.

Abstract
Posttransplantation lymphoproliferative disorders (PTLDs) of T-cell or natural killer (NK)-cell origin are an uncommon heterogeneous group of lymphoid proliferations that fulfill the criteria for one of the T- or NK-cell lymphomas/leukemias. This report summarizes 130 T/NK-cell PTLDs reported in the literature or presented at the Society for Hematopathology/European Association for Haematopathology Workshop on T/NK-cell malignancies. The T/NK-cell PTLDs occur at a median of 66 months following transplantation and are usually extranodal. The most common types reported are peripheral T-cell lymphoma, unspecified, and hepatosplenic T-cell lymphoma. Approximately one third are Epstein-Barr virus (EBV)+. The median survival is 6 months. EBV+ cases have a significantly longer survival than EBV- cases, even when indolent T-cell large granular lymphocytic leukemias are included among the EBV- cases. Many T/NK-cell PTLDs have been treated with chemotherapy, often together with decreased immunosuppression, but there are infrequent patients who have done well without chemotherapy or radiation.

Abstract
It is uncertain whether tumors arising in transplant patients resemble ones that develop de novo in pathogenesis, morphology, and behavior. This study sought to investigate some clinical, morphological, and immunohistochemical features of several posttransplantation malignancies compared with similar de novo tumors. The study group consisted of 40 malignant tumors encountered in 1350 transplant patients (1229 kidneys, 113 livers, 8 hearts) between 1986 and 2006. Tumors with 3 or more examples were compared with randomly selected controls. These included Kaposi's sarcoma (n=14); extranodal lymphoma (n=9); squamous cell carcinoma (n=6); and nodal lymphoma (n=3). The variables that were analyzed were the localization, predisposing lesions, degree of differentiation, and host response. For lymphomas, we also determined histological subtype, origin, and Ki-67 proliferation index. Most tumors (36/40, 90%) occurred in patients with renal transplants. However, the relative frequency was higher among liver transplant cases (3.53% vs 2.92% for kidney transplants). No malignancy was seen in heart transplant cases. Squamous cell carcinomas were better differentiated (P<.05) compared with controls and they were more frequently associated with precursor lesions (P<.05). Kaposi's sarcomas involved internal organs more frequently in posttransplant patients, and the Ki-67 proliferation index was higher in posttransplantation nodal lymphomas. However, these factors were not significantly different (P>.05). Our findings suggested that certain posttransplantation malignancies display unique characteristics compared with their de novo counterparts.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) following solid organ transplantation is an important form of post-transplant malignancy. PTLD is typically associated with Epstein-Barr virus (EBV) and occurs in the setting of profound immunosuppression resulting in a deficiency of EBV-specific cytotoxic T lymphocytes (CTL). Predisposing factors include EBV mismatch between donor and recipient, use of immunosuppression especially T-cell depletive therapies and genetic predisposition of recipients. The standard approach has been to reduce immunosuppression but is often insufficient to induce tumour regression. Further understanding of the immunobiology of PTLD has resulted in improved monitoring techniques (including EBV viral load determined by polymerase chain reaction) and newer treatment options. Recent work has highlighted a potential role for dendritic cells in both the pathogenesis and treatment of PTLD. Current treatment modalities include adoptive immunotherapy using ex vivo generated autologous EBV-specific CTL or allogeneic CTL, cytokine therapies, antiviral agents, and more recently, rituximab and dendritic-cell based therapies. This review focuses on the developments and progress in the pathogenesis, diagnosis and treatment of PTLD.

Abstract
A 58-year-old lung transplant patient developed worsening shortness of breath and indurated erythematous plaques on the lower left leg. A skin biopsy specimen revealed a dense angiocentric and angioinvasive infiltrate in the mid to reticular dermis and panniculus containing large, atypical lymphocytes with convoluted nuclei and prominent nucleoli. Immunohistochemical stains showed that the atypical cells were of B-cell origin, and that Epstein-Barr virus was present. Molecular studies demonstrated B-cell clonality. The patient was successfully treated with rituximab. The clinical and pathologic features in this case represent posttransplantation lymphoproliferative disease with features of lymphomatoid granulomatosis. The case also highlights the importance of clinical and pathologic examination of cutaneous lesions in the evaluation of lymphoproliferative disorders for patients undergoing transplantation.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is an increasingly recognized complication of solid organ and hematopoietic stem cell transplantation. PTLD represents a spectrum of polyclonal and monoclonal lymphoproliferation, generally of B cells. Prompt diagnosis is key and requires a high index of suspicion. An increasing variety of highly effective therapies, including immune modulation via reduction in immunosuppression, monoclonal antibodies, and cellular therapy, have dramatically improved the cure rates of this once devastating disease.

Abstract
Atopic dermatitis (AD) is a chronic or chronically relapsing inflammatory skin condition that primarily affects children. Topical corticosteroids have been the mainstay of treatment since the late 1950s. While providing excellent short-term efficacy, topical corticosteroid usage is limited by potential adverse effects, including impairment of the function and viability of Langerhans cells/dendritic cells. The recently introduced topical calcineurin inhibitors pimecrolimus cream 1% (Elidel) and tacrolimus ointment 0.03 and 0.1% (Protopic) exhibit a more selective mechanism of action and do not affect Langerhans cells/dendritic cells. For the immune system of young children 'learning' to mount a balanced Th1/Th2 response, this selective effect has particular benefits. In clinical experience, topical calcineurin inhibitors have been shown to be a safe and effective alternative to topical corticosteroids in almost 7 million patients (>5 million on pimecrolimus; >1.7 million on tacrolimus). Topical pimecrolimus is primarily used in children with mild and moderate AD, whereas tacrolimus is used preferentially in more severe cases. None of the topical calcineurin inhibitors have been associated with systemic immunosuppression-related malignancies known to occur following long-term sustained systemic immunosuppression with oral immunosuppressants (e.g., tacrolimus, cyclosporine A, and corticosteroids) in transplant patients. Preclinical and clinical data suggest a greater skin selectivity and larger safety margin for topical pimecrolimus.
