A 12-year review of granular cell tumors at Howard University Hospital is reported. Sixty-one cases were studied (56 patients). A female preponderance was clearly established and multicentricity of lesions constituted a higher percentage than previously reported in other series. Malignant transformation was not found. Electron microscopic studies tended to support the Schwann cell origin theory for the tumor but no conclusion could be drawn as to whether or not the lesion is neoplastic, degenerative, or metabolic in nature.
本文报道了霍华德大学医院对颗粒细胞瘤进行的一项为期12年的回顾性研究。共研究了61例病例（56名患者）。明确显示女性居多，且病变的多中心性比例高于其他系列先前报道的比例。未发现恶性转化。电子显微镜研究倾向于支持肿瘤起源于施万细胞的理论，但对于该病变本质上是肿瘤性、退行性还是代谢性的，无法得出结论。
