Intravascular accumulation of atypical large lymphoid cells is a rare condition that necessitates a differential diagnosis of intravascular lymphoma (IVL). Recently, a non-neoplastic condition known as benign atypical intravascular CD30+ T-cell proliferation (BAITP) has been identified. This condition is characterized by CD30+ and CD3+ or CD4+ atypical T-cells and is often associated with trauma and chronic inflammation. This case highlights atypical intravascular lymphoid cells of the uterine cervix that are positive for CD30 and CD56 and can mimic IVL.
非典型大淋巴细胞的血管内积聚是一种罕见情况，需要对血管内淋巴瘤（IVL）进行鉴别诊断。最近，一种被称为良性非典型血管内CD30+ T细胞增殖（BAITP）的非肿瘤性疾病已被识别。这种疾病的特征是CD30+以及CD3+或CD4+非典型T细胞，并且常与创伤和慢性炎症相关。本病例突出了子宫颈的非典型血管内淋巴样细胞，这些细胞CD30和CD56呈阳性，可酷似IVL。
