Testicular Metastasis of Gastrointestinal Stromal Tumor of the Jejunum

Gastrointestinal stromal tumors (GIST) are neoplasm of mesenchymal origin that usually begins in cells of the wall of the gastrointestinal tract. It can be benign or malignant. In this report, we have presented a case of malignant GIST with uncommon site of metastasis. This is of interest because of three reasons. Firstly, metastases to the testis are extremely rare. However, metastases to distally localized organs are not commonly associated with GIST, and finally, to our knowledge this is the first case of malignant GIST metastasis to the testis reported in the world.
