Abstract:
We report the first known case of a metastatic thymic tumor arising from spermatic cord leiomyosarcoma, occurring in a 35-year-old man. He had undergone an orchiectomy 24 months previously and a surgical excision of a subcutaneous metastasis 4 months prior to his current presentation. Computed tomography revealed a 1.5-cm, round-shaped anterior mediastinal mass. A thymectomy was performed and the diagnosis of metastatic leiomyosarcoma was made.

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...
