Malignant granular cell tumor variant is rare and even more if lower extremities are involved. We present a rare case with images of 18F-FDG PET/CT showing 2 hypermetabolic lesions on the right tight with an elevated SUVmax value of 7.50 and 2 adenopathies with an SUVmax almost as high as the lesions. Histopathologic sample after complete excision confirmed malignant granular cell tumor with lymph node metastases.
恶性颗粒细胞瘤变异型较为罕见，尤其是下肢受累的情况更为罕见。我们报告了一例罕见病例，其 18F-FDG PET/CT 图像显示右侧臀部有 2 个高代谢病灶，SUVmax 值为 7.50，2 个淋巴结转移病灶 SUVmax 值几乎与病灶一样高。完全切除后的组织病理学样本证实为恶性颗粒细胞瘤伴淋巴结转移。
