Littoral cell angioma (LCA) is a rare benign tumor originating exclusively from the venous sinus lining cells of the splenic red pulp. These cells are unique in having a distinctive hybrid endothelial/histiocytic phenotype. Also, there are reports of the association of LCA with internal malignancies. We present a case report highlighting an unusual association of LCA with conventional renal cell carcinoma (RCC), masquerading as a metastatic lesion. Knowledge of such an association is necessary to avoid misdiagnosis and prevent potential overtreatment.
血管外皮细胞瘤(LCA)是一种罕见的良性肿瘤,仅起源于脾红髓静脉窦衬里细胞。这些细胞具有独特的混合性内皮/组织细胞表型。此外,有报道称 LCA 与内脏恶性肿瘤有关。我们报告 1 例病例,突出显示 LCA 与常规肾细胞癌(RCC)的不常见关联,表现为转移病变。了解这种关联对于避免误诊和防止潜在的过度治疗是必要的。
