Background: CD5-positive diffuse large B-cell lymphoma (CD5+ DLBCL) is a rare subtype of DLBCL with invasive clinical features and poor prognosis. Current clinical variables based on prognostic systems for DLBCL are inadequate to accurately stratify the prognosis of CD5+ DLBCL.
Methods: A total of 195 CD5+ DLBCL patients were retrospectively recruited from nine centers in Huaihai Lymphoma Working Group. MaxStat analysis was used to identify optimal cutoff points for continuous variables; univariable and multivariable Cox analyses were used for variable selection; Kaplan-Meier curve was used to analyze the value of variables on prognosis; and C-index, Brier score, and decision curve analysis were measured for predicting model performance.
Results: The derivation and validation cohorts consisted of 131 and 64 patients. Of the whole cohort, median age at diagnosis was 61 years, of whom 100 (51.28%) were males and the 5-year overall survival rate was 42.1%. MYC, BCL-2, and the coexpression of MYC/BCL-2 could distinguish the survival of CD5+ DLBCL. Multivariable analysis showed that age, IPI, red blood cell count, neutrophil count, MYC expression, and hepatosplenomegaly were independent predictors, and the prognostic nomogram was developed. The C-index of the nomogram was 0.809 in the derivation and 0.770 in the validation cohort. Decision curve analysis proved that compared with IPI, the specific nomogram showed a better identification in CD5+ DLBCL.
Conclusion: The proposed nomogram provided a valuable tool for prognosis prediction in patients with CD5+ DLBCL.

CD5 expression is seen in 5%-10% of de novo diffuse large B-cell lymphomas (DLBCLs). Primary large B-cell lymphoma of the central nervous system (PCNS-LBCL) also exhibits CD5 expression in a minority of cases, however, clinicopathological and molecular features remain largely unclarified. Here we present the clinical, molecular, and pathological features of 11 CD5-positive () PCNS-LBCL cases, occupying 6.

Introduction: Erythema nodosum (EN) is the most common form of panniculitis. EN can be idiopathic or secondary to an underlying systemic disease, infection, drug use, or tumor. CD5-positive diffuse large B-cell lymphoma (CD5+ DLBCL) is a relapsed and refractory lymphoma, and further understanding of its pathology is required.

Lymphoma is a common malignancy in children. It is the second most common malignancy in children older than 1 year of age. Most extranodal non-Hodgkin lymphoma (NHL) in the head and neck is usually caused by diffuse large B-cell lymphoma (DLBCL), but pediatric DLBCL with cluster of differentiation (CD)5 expression is rarely discussed in the literature.
