Testicular cavernous hemangioma presenting as an ipsilateral lesion in a child with multicystic dysplastic kidney

Childhood malignant testicle tumors are very rare. In the literature to date, it has been reported that there are only 24 cavernous hemangioma cases existing in English literature. In this study, we discuss a testicular mass case which was diagnosed as cavernous hemangioma. The patient, who followed for left multicystic dysplastic kidney since his birth, was admitted to our clinic with complaints of left testicular mass and pain at 1-year of age. Histopathological investigation revealed cavernous hemagioma. Even if it has its characteristic ultrasonographic findings, radiology is too far beyond to eliminate the malignancy, final diagnosis can only be made after orchiectomy.
