CIC fusion-positive sarcoma of the spermatic cord.

In addition to germ cell tumors and tumors of the sex cord stroma, the WHO classification of testis and paratesticular tumors also contains malignant soft tissue tumors. Among them, liposarcomas of the spermatic cord are the most common entities. Other mesenchymal tumors with smooth muscle, skeletal muscle, fibroblastic/myofibroblastic, or nerve sheath differentiation are rare.

Ovarian-type epithelial tumours of the testis: immunohistochemical and molecular analysis of two serous borderline tumours of the testis.

Tumours of ovarian-epithelial type of the testis, including serous borderline tumours, represent very rare entities. They are identical to the surface epithelial tumours of the ovary and have been reported in patients from 14 to 68 years of age. We describe two cases of a 46- and a 39-year old man with incidental findings of intratesticular masses of the left respectively right testis.
