Objective: De novo CD5-positive (CD5+) diffuse large B-cell lymphoma (DLBCL) has different clinical characteristics compared with CD5-negative (CD5-) DLBCL. However, few studies have been reported in Chinese cohorts. We investigated the clinical features and prognosis of patients with CD5+ DLBCL and summarized the related literature.
Methods: Data from 245 patients with newly diagnosed DLBCL were retrospectively assessed.
Results: Thirty-one and 214 patients were diagnosed with CD5+ DLBCL or CD5- DLBCL, respectively. In the CD5+ DLBCL group, there were significantly higher proportions of patients with older age (≥60 years), International Prognostic Index (IPI) ≥3, Eastern Cooperative Oncology Group (ECOG) scores ≥ 2, bone marrow involvement, positive B-cell lymphoma 2 expression, and positive MYC expression. Survival analysis showed that CD5+ DLBCL had a markedly poorer 2-year progression-free survival than CD5- DLBCL (18.2% vs. 56.2%). Univariate analysis indicated that age ≥60 years, ECOG score ≥ 2, IPI ≥ 3, B symptoms, and no rituximab-based treatment were poor predictive factors for overall survival (OS). Multivariate analysis revealed that B symptoms and no rituximab-based treatment, but not positive CD5 expression, were independent factors for OS.
Conclusions: Patients with CD5+ DLBCL had heterogeneous clinical characteristics and poor survival. The development of more targeted and effective therapies is needed.

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.
