Abstract

Primary effusion lymphoma (PEL) is a B‑cell non‑Hodgkin's lymphoma that is usually characterized by lymphomatous effusions in the body cavity without any detectable tumor masses. According to the World Health Organization (WHO) schema for tumor classification, PEL is defined by the presence of human herpesvirus 8 (HHV8) in malignant lymphoid cells. However, a subset of effusion‑based B‑cell lymphoma is not HHV8‑positive and exhibits different clinicopathological characteristics. The 2017 WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues does not list HHV8‑negative effusion‑based lymphoma, which remains an underappreciated B‑cell lymphoma, as an individual entity. The present study reports a case of this rare type of lymphoma with indolent clinical behavior in a 75‑year‑old male patient receiving only symptomatic treatment. Additionally, a review of similar cases reported in the English literature is presented.
