Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening disorders. The incidences, mortality and cost of SJS and TEN in US adults are not well-characterized. We analyzed data from the 2009-2012 Nationwide Inpatient Sample, containing a representative 20% sample of all hospitalizations in the US. SJS, SJS/TEN and TEN were identified by a validated algorithm using ICD-9- CM codes. The mean incidences of SJS, SJS/TEN and TEN were 9.3, 1.6, and 1.9 per million people per year, respectively...

Estella Matutes, Carlos Montalban
Extranodal mucosa associated lymphoid tissue (ENMALT) marginal zone lymphomas may arise at any site of the body. The most frequent localizations other than gastrointestinal and eye are salivary gland, skin, lung and thyroid. These lymphomas usually arise in a setting of inflammation due to a persistent infection or autoimmune diseases such as Sjogren syndrome in salivary MALT lymphomas and Hashimoto's thryroiditis in thyroid lymphomas. They affect middle-aged patients with a female predominance when lymphoma arises in certain locations...

Maurilio Ponzoni, Andrés J M Ferreri
In the last decades some bacteria have been associated with a various extent with marginal zone (extra nodal, nodal and splenic types) lymphomas are frequently associated with chronic infections, with important clinical, molecular, biological, and therapeutic implications. The well-known correlation between Helicobacter pylori and gastric MALT-lymphoma, the recently reported links between Chlamydia psittaci and ocular adnexal MALT-lymphoma and Borrelia burgdorferi and cutaneous MALT lymphoma constitute the most studied examples; in addition, Campylobacter jejuni and some more recent associations encompassing Achromobacter xylosoxidans and Haemophilus influenzae will be further reported...

Ocular adnexal marginal zone lymphoma (OAML) represents 1-2% of all non Hodgkin lymphomas. In the last few years many advances in understanding the pathogenesis and the molecular basis involved in its development have been done. Many potential risk factors have been proposed; a dysregulation of immune response in association with a chronic antigenic stimulation, have been hypothesized as possible pathogenic mechanism. In particular, Chlamydia psittaci infection has been related to OAML arising, and eradicating antibiotic therapy has been addressed as a safe and cost-effective approach...

INTRODUCTION: Ocular adnexal lymphoproliferative disorders (OALDs) are almost exclusively of B-cell origin, with the majority being extra-nodal marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT). The comparative efficacy of involved field radiation therapy (IFRT) in MALT vs. non-MALT OALDs is not known. MATERIALS AND METHODS: We present a single-center, large cohort, retrospective study of the efficacy of IFRT in OALDs. Failure-free survival (FFS), complete remission, and local, regional, and distant failure were determined for 112 patients with MALT OALDs (n = 71) and non-MALT OALDs (n = 41) cohorts...

Lymphoproliferative diseases of the central nervous system are rare, diagnostics and treatment are accordingly challenging. Since the introduction of the 2008 WHO lymphoma classification, primary CNS DLBCL - also covering the associated primary ocular (vitreoretinal) lymphoma - is a separate entity. The special localization is related with a series of newly recognized genetic, genomic and immunologic features directing to the strong interaction between transformed lymphoma cells, neural tissue components and the local immune response...

Human T cell leukemia virus type 1, also known as human T lymphotropic virus type 1 (HTLV-1), is a retrovirus that encodes a reverse transcriptase, which translates viral RNA into a DNA provirus that is integrated into the host genome. The virus was found to be a causative agent of adult T cell leukemia/lymphoma (ATL) in the early 1980s, and was also found to cause the neurological disorder tropical spastic paraparesis (TSP)/HTLV-1-associated myelopathy (HAM) and the inflammatory disorder HTLV-1 uveitis in the mid 1980s and early 1990s, respectively...

Ocular marginal zone lymphoma is a common type of low-grade B-cell lymphoma. To investigate the genomic changes that occur in ocular marginal zone lymphoma, we analyzed 10 cases of ocular marginal zone lymphoma using whole-genome and RNA sequencing and an additional 38 cases using targeted sequencing. Major genetic alterations affecting genes involved in nuclear factor (NF)-κB pathway activation (60%), chromatin modification and transcriptional regulation (44%), and B-cell differentiation (23%) were identified...

BACKGROUND/PURPOSE: To describe a case of histopathologic clinical correlation of sarcoidosis-related multifocal chorioretinitis in an elderly individual. METHODS: This is a single case report and review of the pertinent literature. A 72-year-old white woman with a history of asthma was referred with bilateral asymmetric low-grade chronic panuveitis with advancing peripheral punched-out chorioretinal lesions despite systemic corticosteroid treatment. RESULTS: Coalescent chorioretinal punched-out lesions on fundus examination in the more severely affected right eye did not respond to corticosteroid treatment, and the refractory nature resulted in a suspicion of intraocular lymphoma despite a previous inconclusive diagnostic vitrectomy result...

Exophthalmos is a common and important symptom in orbital consultation. It can be either uni- or bilateral. A wide spectrum of benign and malignant diseases has to be considered and evaluated for differential diagnosis, in order to maintain complete ocular function and to lead the patient to adequate therapy. Exophthalmos can be accompanied by variable symptoms, ranging from neurogenic or myogenic to corneal alterations. Symptoms at presentation depend on the underlying disease and may manifest systemically...

Primary Sjögren's syndrome (SS) is a common chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands, mainly salivary and lacrimal, resulting in oral and ocular dryness, although virtually any organ system can be affected. SS-related systemic manifestations are classified as either related to the presence of periepithelial infiltrates in exocrine and parenchymal organs or resulting from immunocomplex deposition due to B cell hyperactivity with increased risk for B cell lymphoma development...

BACKGROUND: Vitreoretinal lymphoma (VRL), the most common lymphoma of the eye, is a rare form of primary CNS lymphoma (PCNSL). Most frequently a high-grade diffuse large B cell lymphoma, VRL can cause vision loss and its prognosis remains dismal: the overall survival time is 3 years after diagnosis. Radiotherapy and chemotherapy are used but remain frequently ineffective, and no standardized treatment regimen exists. Furthermore, no biologically targeted treatments, based on the genetic profile of the tumor, are available, as VRL has hitherto not comprehensively been profiled...

CLINICAL CASE: A 49-year-old woman experienced a local relapse of a primary follicular lymphoma (FL) of the conjunctiva. She received 4 weekly intra-lesional injections followed by 6 monthly injections of rituximab (6mg/ml). A clinical response was achieved after first injection. No adverse ocular event or signs of lymphoma relapse were seen after 10 months of follow-up. DISCUSSION: Intralesional administration of rituximab for treating primary FL of the conjunctiva was an effective and safe therapeutic option; therefore it could be an alternative to other conventional treatments, such as radiotherapy or chemotherapy...
