Primary effusion lymphoma (PEL) is a Kaposi's sarcoma herpes virus (KSHV)–induced lymphoma that typically arises in body cavities of HIV-infected patients. PEL cells are often co-infected with Epstein-Barr virus (EBV). “PEL-like” lymphoma is a KSHV-unrelated lymphoma that arises in body cavities of HIV-negative patients. “PEL-like” lymphoma is sometimes EBV positive. The derivation of PEL/“PEL-like” cells is unclear.

体腔积液淋巴瘤的间皮起源的证据

原发性渗出性淋巴瘤（PEL）是由卡波西氏肉瘤疱疹病毒（KSHV）诱导的淋巴瘤，通常发生在感染HIV的患者的体腔中。PEL细胞通常与爱泼斯坦-巴尔病毒（EBV）共同感染。“ PEL样”淋巴瘤是与KSHV不相关的淋巴瘤，出现在HIV阴性患者的体腔中。“ PEL样”淋巴瘤有时是EBV阳性。PEL /“类PEL”细胞的来源尚不清楚。
