Abstract:
Salivary gland tumors are a rare, histologically heterogeneous group of tumors which constitute approximately 4–6 % of all head and neck neoplasms. In 2/3 of cases they are benign, especially in the parotid gland. We report about a rare tumor of the parotid gland presenting as an extraskeletal chondroma. Histologically there were multiple S 100 protein-positive nests of chondrocytes. The externally completed cytology suspected a pleomorphic adenoma, nevertheless, the final histopathological findings showed another tumor entity.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
