Given the patient's presentation of generalized lymphadenopathy, B symptoms, fatigue (probably from anemia), hepatosplenomegaly, immunophenotyping results of flow cell cytometry, and central nervous system (CNS) involvement, blastoid mantle cell lymphoma (MCL) is the most likely diagnosis. Although small lymphocytic lymphoma (SLL)/chronic lymphocytic leukemia (CLL) and diffuse large B-cell lymphoma (DLBCL) most often occur in men 60-70 years old with similar clinical findings, an initial presentation with a stage IV involvement is rare; moreover, SLL/CLL and DLBCL are typically CD23 positive. Pleomorphic MCL displays larger and more pleomorphic cells with irregular nuclei, prominent nucleoli, and pale cytoplasm, resembling DLBCL.

MCL is a rare type of mature B-cell lymphoma that was first described in 1992 and was recognized by World Health Organization in 2001. MCL represents 3%-10% of all non-Hodgkin lymphoma cases, with an incidence between 0.50 and 1.0 per 100,000 population. Men are more likely than women to present with MCL by a ratio of 3:1, with a median age at presentation of 67 years. Clinical presentation includes advanced disease with B symptoms (eg, night sweats, fever, weight loss), generalized lymphadenopathy, abdominal distention associated with hepatosplenomegaly, and fatigue. MCL usually affects the lymph nodes, with the spleen and bone marrow being significant sites of the disease. Stage IV disease is present in 70% of patients; the gastrointestinal tract, lung, pleura, and CNS are also frequently affected. 

Besides classic MCL, several variants have been described that exhibit specific morphologic features, including small cell variant mimicking SLL marginal zone-like MCL (resembling marginal zone lymphoma), in situ mantle cell neoplasia (associated with indolent course), and two aggressive variants, including blastoid and pleomorphic MCL. These blastoid and pleomorphic variants are defined by cytomorphologic features; the criteria are somewhat subjective, but both are characterized by highly aggressive features and a dismal clinical course. In clinical cohorts, the frequency of these subsets varies widely but probably represents ∼10% of all cases.

Diagnosing MCL requires a multipronged approach. Lymph node biopsy and aspiration with immunophenotyping in MCL reveal monoclonal B cells expressing surface immunoglobulin, immunoglobulin M, or immunoglobulin D that are characteristically CD5+ and pan B-cell antigen positive (eg, CD19, CD20, CD22) but lack expression of CD10 and CD23 and overexpress cyclin D1. Bone marrow aspirate and biopsy are used more for staging than diagnosis. Blood studies commonly reveal anemia and cytopenias secondary to bone marrow infiltration (with 20%-40% of cases showing lymphocytosis > 4000 cells/μL), abnormal liver function tests, and elevated lactate dehydrogenase when tumor burden is high. The term "blastoid mantle cell lymphoma" describes a morphologic subgroup of lymphomas with blastic features that morphologically resemble the lymphoblasts found in lymphoblastic lymphoma/leukemia (roundish nuclei, a narrow rim of cytoplasm, and finely dispersed chromatin).

MCL is associated with a poor prognosis; patients generally experience disease progression after chemotherapy, even with initial treatment response rates ranging from 50% to 70%. The 5-year survival rate is about 50% in the overall population, 75% in persons younger than 50 years, and 36% in those aged 75 years or older. A poorer prognosis is also associated with the presence of the blastoid variant, commonly associated with TP53 mutations. Median survival can vary by as much as 5 years, depending on the expression of cyclin D1 and other proliferation signature genes.

Key clinical point: Comparable prevalence rates of non-alcoholic fatty liver disease (NAFLD) in patients with moderate-to-severe atopic dermatitis (AD) and those with in situ melanoma suggest that AD is not a risk factor for NAFLD.

Major finding: The prevalence rate of NAFLD was similar in patients with AD (24.1%) and those with in situ melanoma (23.2%), but it was significantly higher in patients with moderate-to-severe chronic plaque psoriasis (49.8%) compared with the other two groups (both P < .01). AD was not independently associated with NAFLD (adjusted odds ratio 1.02; 95% CI 0.78-1.26).

Study details: Findings are from a retrospective cross-sectional study including adult patients with moderate-to-severe AD (n = 144), moderate-to-severe chronic plaque psoriasis (n = 466), or in situ melanoma (n = 99).

Disclosures: This study was funded by European Union-Next Generation EU-NRRP M6C2-Investment 2.1 Enhancement and Strengthening of Biomedical Research in the National Health Service. The authors declared no conflicts of interest.

Key clinical point: Atopic dermatitis (AD) negatively affects the prognosis, quality of life (QoL), and work life in young workers with occupational contact dermatitis (OCD).

Major finding: The prevalence of previously diagnosed AD was 41.8%. A higher proportion of workers with vs without AD experienced eczema during the last 3 months of response submission (adjusted odds ratio [aOR] 1.7; P < .001) and reported that OCD had negatively affected their choice of jobs and occupations (aOR 1.4; P < .001). Workers with vs without AD had significantly higher mean scores in the emotions (P < .01) and symptoms (P < .001) subscales of the Skindex-29 assessment of QoL.

Key clinical point: Atopic dermatitis (AD) negatively affects the prognosis, quality of life (QoL), and work life in young workers with occupational contact dermatitis (OCD).

Major finding: The prevalence of previously diagnosed AD was 41.8%. A higher proportion of workers with vs without AD experienced eczema during the last 3 months of response submission (adjusted odds ratio [aOR] 1.7; P < .001) and reported that OCD had negatively affected their choice of jobs and occupations (aOR 1.4; P < .001). Workers with vs without AD had significantly higher mean scores in the emotions (P < .01) and symptoms (P < .001) subscales of the Skindex-29 assessment of QoL.

Key clinical point: Xyloglucan and pea protein (XG-PP)-based topical treatment shows safety and efficacy outcomes comparable with those of hydrocortisone in pediatric patients with atopic dermatitis (AD).

Major finding: At 8 and 15 days of treatment, both XG-PP and hydrocortisone led to significant decreases in the AD Severity Index (ADSI) score (all P = .00001). Both treatment arms showed similar decrease in ADSI scores at 8 (P = .91) and 15 (P = .92) days. No adverse events were reported in the XG-PP treatment arm.

Study details: Findings are from a prospective multicenter study including 42 pediatric patients with mild-to-moderate AD (age 6 months-12 years) who were randomly assigned to receive either topical XG-PP-based cream or hydrocortisone twice daily for 14 consecutive days.

Disclosures: This study was sponsored by Novintethical Pharma SA. The authors declared no conflicts of interest.

Key clinical point: Patients with atopic dermatitis (AD) have an increased risk for multiple neuropsychiatric conditions; however, the risk profiles for specific neuropsychiatric conditions differ with AD severity.

Major finding: Adults with AD (of any severity level) vs without AD had a higher risk for anxiety (adjusted hazard ratio [aHR] 1.14, 95% CI 1.13-1.15), depression (aHR 1.14, 95% CI 1.13-1.15), and obsessive-compulsive disorder (aHR 1.48, 95% CI 1.38-1.58); the risk for autism increased in patients with mild (aHR 1.55; 95% CI 1.26-1.89) and moderate (aHR 1.40; 95% CI 1.07-1.83) AD and that for attention-deficit/hyperactivity disorder increased in those with mild AD (aHR 1.27; 95% CI 1.03-1.55].

Study details: This population-based cohort study included 625,083 adults with AD who were matched with 2,678,888 control adults without AD.

Key clinical point: Both ciclosporin and methotrexate were effective against severe atopic dermatitis (AD) in children, but ciclosporin resulted in a more rapid response whereas methotrexate led to more sustained disease control even after treatment discontinuation.

Major finding: At 12 weeks, a significantly higher proportion of patients achieved 50% improvement in Objective Severity Scoring of Atopic Dermatitis scores (o-SCORAD-50) with ciclosporin vs methotrexate (P = .012). However, at 60 weeks, the proportion of patients who achieved o-SCORAD-50 was higher with methotrexate vs ciclosporin (P = .022). Adverse event rates were comparable in both groups.

Study details: The TREatment of severe Atopic Eczema Trial included 103 children with severe AD (age 2-16 years) who were unresponsive to topical treatments and were randomly assigned to receive ciclosporin or methotrexate.

Disclosures: This study was funded by the UK Medical Research Council/National Institute for Health Research (NIHR). Some authors, including the lead author, declared receiving consulting fees, advisory fees, or research funding from various sources, including UK NIHR.
