Erythema Nodosum Secondary to CD5-Positive Diffuse Large B-Cell Lymphoma as a Paraneoplastic Symptom: A Case Report.

ABSTRACT:

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. We report a case of newly diagnosed CD5+ DLBCL with concomitant EN. Within the scope of our search, there were no reports of CD5+ DLBCL complicated with EN.

Case presentation

A 79-year-old woman experienced swelling, warmth, redness, and pain in both legs and a mass lesion on the right side of the back at almost the same time. The respective lesions were diagnosed as EN and CD5+ DLBCL by biopsy. With chemotherapy, the lymphoma and EN improved in parallel
