The clinical characters of paratesticular rhabdomyosarcoma in children

Objective To explore the clinical characters and treatment of paratesticular rhabdomyosarcoma (RMS) in children. Methods The clinical data of a child patient with paratesticular RMS was retrospectively analyzed and the related literatures were reviewed. Results The patient presented with a progressively enlarging mass in left scrotum. Biochemical test, immunologic test, tumor marker showed no abnormalities. Ultrasound demonstrated a solid lesion in the left scrotum with rich blood supply signals inside. Enhanced magnetic resonance showed the same result as ultrasound. Radical left testicular resection was performed. Pathological diagnosis was paratesticular RMS with positive result of Desmin and Myogenin. A painless mass was found in the left scrotum on the third day after operation, then left scrotum resection was performed. VAC chemotherapy was used after operation. Follow-up for 8 months, the patient survived with tumor free. Conclusions The paratesticular RMS can present as a mass in scrotum and is easily considered to be carcinoma of testis because of its location. Correct diagnosis and reasonable treatments can be made by pathologic examination after radical resection. Key words: Child; Rhabdomyosarcoma; Paratesticular; Diagnosis
