Von Recklinghausen’s disease is an autosomal dominant disease characterized by café au lait spots and neurofibroma of the skin. It may be accompanied by nervous system, bone, eye, or gastrointestinal tract symptoms. In addition to neurofibroma, benign tumors, such as leiomyomas, non-epithelial tumors accompanied by gastrointestinal stromal tumor, smooth muscle sarcoma, and epithelial malignant tumors like colon cancer or esophageal cancer have been reported in the gastrointestinal tract. There are many reports of leiomyoma in the small intestine, but reports of leiomyoma in the gastrointestinal tract above the stomach are rare. We report a case of leiomyoma of the tongue in a patient with von Recklinghausen’s disease.
