title: Lingual squamous cell carcinoma surrounded by granular cell tumor.
abstract: The granular cell tumor (GCT) is an uncommon, benign lesion with a preference for subcutaneous sites. In the head and neck, the tongue is the most common site, followed by the larynx. We experienced a case of a 27-year-old woman with lingual squamous cell carcinoma (SCC) surrounded by GCT. The pathological findings established that the lesion was SCC covered by GCT in the midline of the tongue. The size of the mass was very small, however, so we excised it in a diamond shape. There is an interesting association between GCTs and other malignant neoplasms. However, no causal relationship between GCT and these other carcinomas has been established. Here we report on an SCC coexisting with GCT at the same site as a median tongue lesion and review the literature.
