Paratesticular region tumors are uncommon and include epithelial, mesothelial, and mesenchymal derived lesions. While adenomatoid tumor is the most common benign paratesticular tumor, malignant mesothelioma is a very rare but well documented occurrence. Liposarcoma and rhabdomyosarcoma are the most common malignant paratesticular tumors in adults and children, respectively. Other primary epithelial tumors that can arise from this area include benign and malignant rete testis lesions and ovarian-type epithelial tumors. We report a case of SCC arising from the tunica vaginalis in the context of chronic hydrocele. To the best of our knowledge, SCC in paratesticular region has been reported twice in the English literature.
