Comparsion of staining characteristics of Toto bodies.
Toto bodies are eosinophilic structures that resemble the cells of the superficial cell layer of the oral epithelium. Toto bodies commonly are associated with inflammatory gingival and other mucosal lesions including pyogenic granuloma, irritational fibroma, epulis fissuratum, peripheral giant cell granuloma and inflammatory hyperplastic gingivitis. We evaluated staining characteristics of Toto bodies to establish their origin and to identify their significance in lesions. We investigated pyogenic granuloma, fibroma and leukoplakia with epithelium that exhibited Toto bodies after hematoxylin and eosin (staining. Sections were stained with Alcian blue, periodic acid-Schiff and Ayoub-Shklar stains to evaluate staining intensity and distribution. More Toto bodies were found in pyogenic granuloma than in fibroma and leukoplakia. PAS and Alcian blue staining exhibited mild intensity and did not establish the origin of Toto bodies. High staining intensity and diffuse distribution of stain was observed using Ayoub-Shklar staining, which indicated that Toto bodies originate from keratin.

Juvenile hyaline fibromatosis. A histologic and histochemical study.
Histochemical and routine light microscopic studies were performed in nodular skin lesions excised from one patient with juvenile hyaline fibromatosis. The lesions had different times of evolution. Recent lesions showed a high density of fibroblastlike cells embedded in an amorphous matrix of glycoproteins, hyaluronic acid, and small amounts of chondroitin sulfates A and C and of dermatan sulfate. The progressive enlargement of the lesions was due to an increase in the amount of intercellular matrix produced by the cells that progressively displayed a pattern of peripheral stratification. In the older lesions, the matrix was mainly composed by chondroitin sulfates A and C. We suggest that juvenile hyaline fibromatosis represents a disease of the connective tissue with progressive abnormal differentiation to chondroid tissue.
