Lipomas are encapsulated benign tumors typically found in the integument, central nervous system or gastrointestinal tract and represent the most common benign mesenchymal neoplasm in adults. Bladder lipoma is a rare tumor that has been reported in a handful of cases in medical literature. A literature review from PubMed, MEDLINE, EMBASE and Cochrane databases of bladder lipoma yielded less than 20 cases. We report a case of a 69 year-old Moroccan male patient with hematuria as a chief symptom. The diagnosis of bladder lipoma was suspected by flexible fibroscopy and assessed by transurethral resection. Macroscopic and histological examination revealed a lipomatous tumour with no sign of malignancy. There was no recurrence after one year of follow-up. Although bladder lipomas are rare entities, they must be considered in the differential diagnosis of bladder tumor. However, we should always keep in mind that any bladder tumor is malignant until proven otherwise.
脂肪瘤是一种包膜良性肿瘤，通常见于皮肤、中枢神经系统或胃肠道，是成人中最常见的良性间叶性肿瘤。膀胱脂肪瘤是一种罕见的肿瘤，在医学文献中仅报道过少数几例。我们通过 PubMed、MEDLINE、EMBASE 和 Cochrane 数据库对膀胱脂肪瘤的文献进行了回顾，结果不到 20 例。我们报告了一例 69 岁的摩洛哥男性患者，以血尿为主要症状。通过软性纤维镜检查怀疑为膀胱脂肪瘤，并通过经尿道切除术进行评估。大体检查和组织学检查显示为无恶性迹象的脂肪瘤肿瘤。随访 1 年后无复发。尽管膀胱脂肪瘤较为罕见，但在膀胱肿瘤的鉴别诊断中仍需考虑。然而，我们应始终牢记，任何膀胱肿瘤在未确诊之前均被视为恶性。
