Paratesticular rhabdomyosarcoma. A case report

The authors report a case of paratesticular rhabdomyosarcoma in a 21-year-old patient. The clinical features were dominated by left loin pain, inguinoscrotal pain and scrotal swelling. Transillumination was negative. Laboratory markers (alpha-foetoprotein, beta HCG) were normal. Testicular ultrasound showed an enlarged testis, comprising heterogeneous nodules with infiltration of the spermatic cord. Abdominal ultrasonography and CT scan showed a latero-aortic retroperitoneal lymph node mass and a large left kidney. Chest x-ray was normal. Treatment consisted of radical orchidectomy. Histological examination of the operative specimen confirmed the diagnosis of paratesticular rhabdomyosarcoma. The patient was treated by chemotherapy and subsequently developed recurrence with metastases.
