Figure 3

(a) An histological section of lingual mass demonstrating a raised, broad-based polypoid lesion covered with stratified keratinizing epithelium with a central core of smooth muscle (hematoxylin and eosin stain, 2x original magnification). (b) An histological section of lingual mass demonstrating smooth muscle with the salivary gland and duct tissue with intervening adipocyte clusters (hematoxylin and eosin stain, 10x original magnification). (c) An histological section of lingual mass demonstrating smooth muscle with small, thick-walled vessels present (hematoxylin and eosin stain, 10x original magnification). (d) An histological section of lingual mass demonstrating transition between smooth muscle of leiomyomatous lesion and skeletal muscle of dorsal tongue (hematoxylin and eosin stain, 10x original magnification). (e) An histological section of lingual mass with smooth muscle actin stain (2x original magnification).
