Proliferating trichilemmal cyst is considered as a rare tumor that originates in the outer root sheath of hair follicle. Metastatic potential has not been yet fully established. Moreover, histological analysis does not allow precise malignancy prediction. Proliferating trichilemmal cyst glucose metabolism behavior was never previously described. Herein, we report the case of a 62-year-old patient with a left shoulder proliferating trichilemmal cyst showing an intense uptake of ¹⁸F-FDG on PET/CT examination. ¹⁸F-FDG PET/CT could be proposed to optimize diagnostic strategy of patients with proliferating trichilemmal cysts.
增殖性毛鞘瘤被认为是一种罕见的肿瘤，起源于毛囊外根鞘。其转移潜能尚未完全确定。此外，组织学分析也无法准确预测恶性程度。增殖性毛鞘瘤的葡萄糖代谢行为以前从未被描述过。在此，我们报告了一例 62 岁左肩部增殖性毛鞘瘤患者，¹⁸F-FDG PET/CT 检查显示其摄取明显增加。¹⁸F-FDG PET/CT 可用于优化增殖性毛鞘瘤患者的诊断策略。
