Paratesticular embryonal rhabdomyosarcoma; report of a case

Paratesticular rhabdomyosarcoma is the most common pediatric soft-tissue sarcoma, often presenting in the first two decades after birth. Paratesticular embryonal rhabdomyosarcoma [RMS] is a rare tumor arising from the mesenchymal tissues of the spermatic cord, epididymis, testis and testicular tunics. It represents only 7% of all patients entered in the Intergroup Rhabdomyosarcoma Study [IRS] and 17% of all malignant intrascrotal tumors in children less than 15 years old. We report a case of a 14-year-old boy with a left paratesticular tumor, who undergone inguinal surgery and misdiagnosed as being inguinal hernia. During operation, the surgeon realized that the mass was not an inguinal hernia, it seemed like a testicular tumor. A urologist was consulted. The patient underwent left high inguinal orchiectomy. His serum markers for oc-fetoprotein, [3-human chorionic gonadotropin and lactate dehydrogenase were normal. In the result of further investigation, the patient was diagnosed as having paratesticular embryonal rhabdomyosarcoma with retroperitoneal lymph node mass. We referred him to the oncology department. The patient was followed up post-operatively with chemotherapy. Vincristine, doxorubicin and cyclophosphamide [VAC] regimen was used. One year after completion of chemotherapy there was no evidence of the disease. In the patients with testicular and paratesticular mass, ultrasound should be considered the imaging modality of choice for evaluating intra-scrotal pathologies in adolescents

Hemangioma of the spermatic cord: a case report

Hemangioma of the spermatic cord is a benign, extremely rare tumor. We report a case of spermatic cord hemangioma presenting with a painless mass in the left hemiscrotum. Physical examination revealed a non-tender nontransilluminating irregular mass in the left hemiscrotum, above and clearly separate from the left testis. After surgical removal of the mass arising from the spermatic cord, histologic examination showed a benign vascular tumor consistent with cavernous hemangioma. To our knowledge, only a few cases of spermatic cord hemangioma have been previously reported in the literature

Embarazo con espermatozoides testiculares / Pregnacy with testicular spermatozoa

En un paciente con diagnóstico de agenesia de vías espermáticas se propuso afectuar una aspiración epididimaria asociada a FIV (fertilización in vitro). En la exploración excrotal no se encontró epidídimo (debido probablemente a antecedente quirúrgico de biopsia epididimaria) por lo que se efectuó una biopsia testicular. Este material fue procesado obteniéndose escasos espermatozoides (algunos cientos). Estos espermatozoides fueron inyectados en el citoplasma de los ovocitos de la esposa (técnica de ICSI).De los 18 ovocitos inyectados, 3 se dañaron durante el procedimiento y a las 16 horas se observaron signos de fertilización normal en 6 de ellos, prosiguiendo el desarrollo 4 de embriones que fueron transferidos al útero por vía transcervical, 3 en estado de 8 células y uno de 6 células, habiéndosele efectuado previamnete en la zona pelúcida de cada uno de los embriones un orificio de 20 micrones con solución ácida de Tyrode. A los 15 días de la transferencia (2-1-95) el resultado de la subunidad beta de HCG fue positiva, detectándose al mes (2-2-95) por ecografía un embrión de 19 mm, cursando un embarazo normal
