    [A case of paratesticular rhabdomyosarcoma]. Nishida A,Masuda F,Suzuki H,Kurauchi H,Mitani H,Kawahara M Hinyokika kiyo. Acta urologica Japonica A case of paratesticular rhabdomyosarcoma in an 18-year-old male is reported. The patient was admitted for swelling of the right scrotum and right inguinal pain. Malignant tumor of the right testis was suspected and a high inguinal orchiectomy was performed. The pathological diagnosis was paratesticular rhabdomyosarcoma. Following retroperitoneal lymph node extirpation, chemotherapy, so-called CYVADIC therapy, consisting of cyclophosphamide, vincristine, adriamycin and dacarbazine was employed in 3 regions. The patient is in good health without recurrence 16 months after the surgery.
    Embryonal rhabdomyosarcoma of the epididymis presenting as epididymitis: A case report. Wang Hong-Liang,Liu Ling-Yun,Tian Run-Hui,Li Fu-Biao,Guo Kai-Min Molecular and clinical oncology Paratesticular rhabdomyosarcoma (RMS) is an extremely rare malignancy in adults, accounting for 7% of all RMS cases and 6% of all non-germinal intrascrotal tumors. The clinical signs are similar to those of a hydrocele or testicular tumor, typically presenting as a unilateral, painless mass in the inguinal canal or scrotum. No specific serum markers are currently available for this tumor. RMS of the epididymis is extremely rare. Particularly when it is associated with epididymitis, this malignancy is usually overlooked. We herein present a case of epididymal embryonal RMS, manifesting an painful scrotal edema, misdiagnosed as epididymitis. The patient received 3 cycles of adjuvant chemotherapy postoperatively and remained disease-free after 4 years of follow-up. 10.3892/mco.2016.733
    A case of pediatric paratesticular rhabdomyosarcoma with epididymitis. Kim Young-Joo,Huh Jung-Sik,Hyun Chang Lim,Kim Sung Dae The world journal of men's health Paratesticular rhabdomyosarcoma is a rare malignancy arising from the mesenchymal tissues of the spermatic cord, epididymis, testis, and testicular tunica, and accounts for approximately 7% of all rhabdomyosarcomas. It often occurs in children but is known to have a better prognosis than disease at other urogenital sites. Patients typically present with painless unilateral scrotal swelling like a solid testicular tumor. However, we report an unusual case of delayed diagnosis of paratesticular rhabdomyosarcoma accompanied by epididymitis manifesting an painful scrotal swelling. 10.5534/wjmh.2012.30.2.146
    Alveolar paratesticular rhabdomyosarcoma mimicing epididymitis: Case report and literature review. Lei W-H,Wu Wen-Feng,Zhen Jin-Yang,Li Yang-Hui,Li Jie,Xin Jun Medicine RATIONALE:Most patients with paratesticular rhabdomyosarcoma may typically present as a unilateral, painless palpable scrotum mass. However, only a few cases of RMS presenting as painful edema of the scrotum mimicing epididymitis. We herein report an unusual case of alveolar paratesticular rhabdomyosarcoma misdiagnosed as epididymitis. PATIENT CONCERNS:A 19-year-old adolescent, presented to urologist with painful swelling of the scrotum on the left side over the preceding several days. Antibiotics were administered by physician for two months and the pain improved, but the swelling did not fade. DIAGNOSES:Alveolar praratesticular rhabdomyosarcoma. INTERVENTIONS:A left, soft tissue mass in the scrotum without definite metastasis or lymphadenopathy was confirmed by computed tomography (CT) and magnetic resonance imaging. A radical left orchiectomy via the inguinal approach was performed successfully. OUTCOME:The patient received 8 cycles of adjuvant chemotherapy, the patient remains recurrence- and metastasis-free at 13 months after surgery. LESSONS:When paratesticular RMS is presenting with symptoms of epididymitis, this malignant tumor is usually overlooked. When patients complain of painful scrotal swelling, RMS arise from paratesticular tissue should be considered. 10.1097/MD.0000000000011164
