The granular cell tumor or Abrikossoff's tumor is a rare tumor, most often benign in evolution. Malignant forms are exceptional. We report, here, a very rare case of granular cell tumor, localized in the perianal region, in a 54-year-old woman with lung metastases. CT and MRI with contrast showed a locally advanced tumor process in the right para-anal region associated with multiple "balloon release" lung lesions. The diagnosis was confirmed by immunostaining after surgical biopsy. Very few cases of malignant granular cell tumors with lung metastasis have been reported in the literature.
颗粒细胞瘤或阿布里科索夫瘤是一种罕见肿瘤，病程大多为良性。恶性形式极为罕见。在此，我们报告一例非常罕见的颗粒细胞瘤病例，发生于一名54岁女性的肛周区域，并伴有肺转移。增强CT和MRI显示右肛门旁区域有局部进展性肿瘤病变，伴有多个肺部“气囊样”病变。手术活检后通过免疫染色确诊。文献中报道的伴有肺转移的恶性颗粒细胞瘤病例极少。
