Evolución natural del carcinoma embrionario

objective: we report a rare case of advanced testicular cancer that describes the natural progression of testicular cancer without medical treatment. this study also describes the effectiveness of chemotherapy, which was the approach used for treatment. methods: 37 year old male with history of mental retardation, presented to the emergency room with an ulcer on his right scrotum that had been present for a few months. he was diagnosed of pt4 embryonal carcinoma by biopsy. ct scan showed multiple lung nodes. he was treated with five cycles of bleomycin/etoposide/cisplatin with complete response after treatment. results: testicular tumors are the most frequent solid tumors in males between the ages of 20 and 39 years old. testicular tumors represent 1% of all neoplasias diagnosed in males and 0.1% of all male deaths due to cancer. several studies have reported the current real incidence rate of testicular tumors has increased to 3%, which accounts for the diagnosis of 450 new cases of testicular cancer a year in spain. conclusions: the cure rate for patients with intermediate risk non-seminoma is around 70% following a conventional treatment approach of four cycles of bep. the present case is noteworthy because, in our experience, testicular tumors are diagnosed at an early stage without extensively affecting the skin or simulating another type of epithelial tumor. as a result, the present study describes the natural progression of testicular cancer.
